Combustible gases are substances with a low calorific value. This is the main component that is used to supply cities with gas, in industry and other areas of life. The physicochemical characteristics of such gases depend on the presence of non-combustible components and harmful impurities in their composition.

Types and origin of combustible gases

Combustible gases contain methane, propane, butane, ethane, hydrogen, and sometimes with impurities of hexane and pentane. They are obtained in two ways - from natural deposits and artificially. origin - fuel, the result of a natural biochemical process of organic decomposition. Most of the deposits are located at a depth of less than 1.5 km and consist mainly of methane with small admixtures of propane, butane and ethane. As the depth of occurrence increases, the percentage of impurities increases. It is extracted from natural deposits or as associated gases of oil fields.

Most often, natural gas deposits are concentrated in sedimentary rocks (sandstones, pebbles). The covering and underlying layers are dense clayey rocks. The soles are mainly oil and water. Artificial - combustible gases obtained as a result of thermal processing of various types of solid fuels (coke, etc.) and derivative products of oil refining.

The main component of natural gases produced in dry fields is methane with small amounts of propane, butane and ethane. Natural gas is characterized by the constancy of composition, belongs to the category of dry. The composition of the gas obtained during oil refining and from mixed gas-oil deposits is not constant and depends on the value of the gas factor, the nature of the oil and the conditions for the separation of oil and gas mixtures. It includes a significant amount of propane, butane, ethane, as well as other light and heavy hydrocarbons contained in oil, up to kerosene and gasoline fractions.

The extraction of combustible natural gases consists in extracting it from the bowels, collecting, removing excess moisture and preparing it for transportation to the consumer. The peculiarity is that at all stages from the reservoir to the end user, the entire process is sealed.

Combustible gases and their properties

Heat output - the maximum temperature released during the complete combustion of dry gas in a theoretically required amount of air. In this case, the generated heat is spent on heating. For methane, this parameter in ° C is 2043, butane - 2118, propane - 2110.

Ignition temperature - the lowest temperature at which a spontaneous ignition process occurs without the influence of an external source, spark or flame, due to the heat released by the gas particles. This parameter is especially important for determining the permissible surface temperature of devices used in hazardous areas, which must not exceed the ignition temperature. For such equipment, a temperature class is assigned.

The flash point is the lowest temperature at which enough vapor (on the surface of a liquid) is released to ignite from the smallest flame. This property should not be generalized to the ignition temperature, since these parameters can vary greatly.

Gas/steam density. It is determined in comparison with air, whose density is 1.< 1 - растет, >1 - falls. For example, for methane this indicator is 0.55.

Combustible gas hazard

Combustible gases are dangerous because of their three properties:

1. Flammability. There is a risk of fire associated with uncontrolled gas ignition;
2. Toxicity. Risk of poisoning by gas or its combustion products (carbon monoxide);
3. Suffocation due to lack of oxygen, which can be replaced by another gas.

The combustion process is a chemical reaction that involves oxygen. In this case, energy is released in the form of heat, flame. The flammable substance is a gas. The process of gas combustion is possible in the presence of three factors:

• Source of ignition.
• combustible gases.
• Oxygen.

The goal of fire protection is to eliminate at least one of the factors.

Methane

It is a colorless, odorless, flammable gas. Non-toxic. Methane makes up 98% of all natural gases. It is considered the main one that determines the properties of natural gas. It is 75% carbon and 25% hydrogen. Mass cube. meters - 0.717 kg. It liquefies at a temperature of 111 K, while its volume decreases by 600 times. Possesses low reactivity.

Propane

Propane gas is a flammable gas, colorless and odorless. It is more reactive than methane. The content in natural gas is 0.1-11% by weight. Up to 20% in associated gases from mixed gas and oil fields, up to 80% in solid fuel processing products (lignite and black coal, coal tar). Propane gas is used in various reactions to produce ethylene, propylene, lower olefins, lower alcohols, acetone, formic and propionic acids, and nitroparaffins.

Butane

Flammable gas without color, with a peculiar smell. Butane gas is easily compressible and volatile. Contained in petroleum gas up to 12% by volume. They will also be obtained as a result of cracking of petroleum fractions and in the laboratory by the Wurtz reaction. The freezing point is -138 ° C. Like all hydrocarbon gases, it is flammable. Harmful to the nervous system, if inhaled causes dysfunction of the respiratory apparatus. Butane (gas) has narcotic properties.

Ethane

Ethane is a colorless and odorless gas. representative of hydrocarbons. Dehydrogenation at 550-650 0 C leads to ethylene, above 800 0 C - to acetylene. Contained in natural and associated gases up to 10%. It is distinguished by low-temperature distillation. Significant volumes of ethane are released during oil cracking. Under laboratory conditions, it is obtained by the Wurtz reaction. It is the main raw material for the production of vinyl chloride and ethylene.

Hydrogen

Clear, odorless gas. Non-toxic, 14.5 times lighter than air. Hydrogen is similar in appearance to air. It is highly reactive, has wide flammability limits, and is highly explosive. Included in almost all organic compounds. The most difficult gas to compress. Free hydrogen is extremely rare in nature, but it is very common in the form of compounds.

Carbon monoxide

Colorless gas, odorless and tasteless. Weight 1 cu. m - 1.25 kg. It is found in high-calorie gases along with methane and other hydrocarbons. Increasing the proportion of carbon monoxide in the combustible gas lowers the calorific value. It has a toxic effect on the human body.

Application of combustible gases

Combustible gases have a high calorific value, and therefore are highly economical energy fuels. They are widely used for domestic needs, at power plants, in metallurgy, glass, cement and food industries, as automotive fuel, and in the production of building materials.

The use of combustible gases as raw materials for the production of such organic compounds as formaldehyde, methyl alcohol, acetic acid, acetone, acetaldehyde is due to the presence of hydrocarbons in their composition. Methane, as the main component of combustible natural gases, is widely used for the production of various organic products. To obtain ammonia and various kinds of alcohols, synthesis gas is used - a product of the conversion of methane with oxygen or steam. Pyrolysis and dehydrogenation of methane produces acetylene, along with hydrogen and soot. Hydrogen, in turn, is used to synthesize ammonia. Combustible gases, and primarily ethane, are used in the production of ethylene and propylene, which are later used as raw materials for the production of plastics, artificial fibers and synthetic rubbers.

Liquefied methane is a promising type of fuel for many areas of the national economy. The use of liquefied gases in many cases provides great economic benefits, making it possible to reduce material costs for transportation and solve problems of gas supply in certain areas, and allows you to create stocks of raw materials for the needs of the chemical industry.

Solvents, lighter fluid, petroleum, pesticides, paint, kerosene, propane, butane, gasoline, cleaning products are all flammable liquids. These products are used everywhere, especially the various types of fuels and cleaning products that everyone has in the house. When moving or working with any of them, you must follow the safety rules.

If the profession involves working with combustible substances, then it is necessary to know all the issues related to the protection of one's own life and others in the event of a fire. This article describes all the necessary requirements for flammable liquids.

General safety requirements

Any flammable liquid can present a serious health hazard or fire risk if used improperly. If the concentration of the vapor cloud reaches a certain temperature, the liquid will ignite. The substance itself, which is in a calm state, cannot catch fire. Flammable liquids have a high flash point, flammable liquids have a low one, so they are more dangerous to humans.

What to do in case of a spill of any product?

If spilled, immediately open all windows and ventilate the room. Turn off all electrical equipment, as it is a source of sparks that can lead to an explosion. If something gets on clothes - remove it, on the skin - rinse with water as soon as possible. If a large amount of flammable substance has spilled, it is advisable to evacuate all employees and call the fire department.

When a fire spreads, do not try to put it out with water, in the case of such liquids, it will only aggravate the situation. A fire extinguisher is best. It must be stored near the work area.

Always read the label carefully before using any product. To make sure you know how to properly use flammable and combustible liquids.

List of tips:

Do not talk on the phone, listen to music or be distracted by anything else while working with combustible substances.

Working with flammable liquids requires a well-ventilated area. Since the fumes are unsafe, and harmful chemicals can enter the body through the respiratory tract. Many of them are odorless.

Caution is the first rule. Make sure that the product you are working with does not get on your skin or clothes.

If there is a leak, report it to the manager.

Whenever you leave a room where a flammable liquid is stored, inspect it before closing the door.

Never smoke cigarettes where such substances are present. They must be kept away from open flames.

Be aware that there are many hidden sources of ignition, such as in machinery.

When using metal drums, hoses, tubing, make sure they are grounded to prevent buildup of static charge which can be a source of ignition.

Ensure that all containers, faucets, canisters, pumps and other equipment used for storage are suitable for the use of flammable liquids.

Try to avoid flammable substances

The best way to reduce the risk of fire is to avoid such products. If possible, you can replace it with another, less flammable substance. Take a look at your current view and see if there are ways you can do the job more safely.

Take note of the following tips to help you handle flammable liquids properly.

Firstly, you need to take special courses in which the instructor will tell you all the nuances of working with combustible substances.

Secondly, when it comes to safety, the health of others is very important. Follow the requirements for labor protection and do not risk other people's lives.

flashes and spontaneous combustion?

A flammable liquid is the minimum level at which a liquid will release vapor to a surface to ignite. Liquids themselves do not burn. A mixture of fumes and air burns.

Gasoline, with a flash point of -43 °C, is a flammable liquid. Even at low temperatures, it gives off enough vapor to form a combustible mixture with air.

Phenol is a flammable liquid. It has a flash point of 79°C (175°F). Therefore, its level must exceed 79 °C before it can ignite in air.

The autoignition temperature of most common liquids ranges from 300°C (572°F) to 550°C (1022°F).

Flammable limits for explosives

The lower flammable limit is the proportion of vapors in the air above which a fire cannot occur because there is not enough fuel. Vapors with a higher density than air tend to be more dangerous because they can flow along the floor and accumulate in low places.

The upper flammable limit is the proportion of vapor in the air when there is not enough air to ignite.

Flammable liquids are explosive, and these limits give a range between the lowest and highest vapor concentrations in the air. That is, using the ignition limits, you can determine which substance will burn and which can explode.

For example, the lower explosive limit of gasoline is 1.4%, and the upper limit is 7.6%. This means that this liquid can ignite when in air at levels between 1.4% and 7.6%. Vapor concentrations below the explosive level are too low to ignite, more than 7.6% may cause an explosion.

Flammable limits serve as guides to hot spots.

Why are these substances dangerous?

At normal room temperature, flammable liquids can release quite a lot of vapors that form flammable mixtures with air. As a result, they can pose a serious fire hazard. Flammable liquids burn very quickly. They also emit large amounts of thick, black, poisonous smoke.

Flammable liquids at temperatures above their flash point can also cause serious fires.

Spraying flammable and combustible liquids into the air will result in a fire if there is an ignition source. Pairs of substances are usually invisible. They are difficult to detect unless special tools are used.

Flammable and flammable liquids are easily absorbed into wood, fabric and cardboard. Even after removing them from clothing or any other coverings, they can still be dangerous, giving off harmful fumes.

What danger do such liquids pose to the body?

Such substances bring great harm during a fire and explosion. They are hazardous to health. Flammable liquids can cause irreparable damage to the human body, depending on the specific material and method of exposure:

1. Vapor inhalation.
2. Contact with eyes or skin.
3. Swallowing liquid.

Most flammable liquids, flammable substances are dangerous to humans. Many of them are stored incorrectly and undergo incompatible chemical reactions, which can harm even more.

The information given on labels and containers should tell you about all the hazards for the flammable substances with which the person works.

For example, propanol (also known as isopropanol or isopropyl alcohol) is a colorless liquid with a pungent odor that resembles a mixture of ethanol and acetone. Vapors are heavier than air and can travel long distances. High levels of vapors can cause headache, nausea, dizziness, drowsiness, incoordination. The substance may also cause respiratory or eye irritation.

How to properly store substances in production areas, workshops, laboratories and similar workplaces

It should be recognized that for practical purposes where liquids are used, it will most likely be necessary to store them in the workshop. Only a minimal amount of such substances can be placed in the work area, but even they should be used during the day or changed location. Actual storage time figures will depend on work activities, organizational arrangements, fire risks in the workshop and work area. The storage of flammable liquids in large quantities at home is prohibited. All responsibility will lie with the owners.

Containers for flammable liquids must be closed. They should be placed in specially designated areas, away from the immediate processing area and not endangering the workshop and work area.

Flammable liquids must be stored separately from other hazardous substances that may increase the risk of fire or compromise the integrity of the container or cabinet (drawer), such as oxidizers and corrosive materials.

What if the quantity exceeds the set maximum?

materials must be stored or handled in the work area;

the size of the workshop and the number of people working there should be taken into account;

the amount of liquid processed in the workshop should not exceed the norms established by the enterprise;

The workshop should be well ventilated.

Must be from a workshop where they work with explosives.

A lot of pathological changes occurring in the body accompany the pain syndrome. To combat such symptoms, NSAIDs, or remedies, have been developed. They perfectly anesthetize, relieve inflammation, reduce swelling. However, the drugs have a large number of side effects. This limits their use in some patients. Modern pharmacology has developed the latest generation of NSAIDs. Such drugs are much less likely to cause unpleasant reactions, but they remain effective drugs for pain.

Impact principle

What is the effect of NSAIDs on the body? They act on cyclooxygenase. COX has two isoforms. Each of them has its own functions. Such an enzyme (COX) causes a chemical reaction, as a result of which it passes into prostaglandins, thromboxanes and leukotrienes.

COX-1 is responsible for the production of prostaglandins. They protect the gastric mucosa from unpleasant effects, affect the functioning of platelets, and also affect changes in renal blood flow.

COX-2 is normally absent and is a specific inflammatory enzyme synthesized due to cytotoxins, as well as other mediators.

Such an action of NSAIDs as inhibition of COX-1 carries many side effects.

New developments

It is no secret that the drugs of the first generation of NSAIDs had an adverse effect on the gastric mucosa. Therefore, scientists have set themselves the goal of reducing undesirable effects. A new release form has been developed. In such preparations, the active substance was in a special shell. The capsule was made from substances that did not dissolve in the acidic environment of the stomach. They began to break down only when they entered the intestines. This allowed to reduce the irritating effect on the gastric mucosa. However, the unpleasant mechanism of damage to the walls of the digestive tract still remained.

This forced chemists to synthesize completely new substances. From previous drugs, they are fundamentally different mechanism of action. NSAIDs of the new generation are characterized by a selective effect on COX-2, as well as inhibition of prostaglandin production. This allows you to achieve all the necessary effects - analgesic, antipyretic, anti-inflammatory. At the same time, NSAIDs of the latest generation make it possible to minimize the effect on blood clotting, platelet function, and the gastric mucosa.

The anti-inflammatory effect is due to a decrease in the permeability of the walls of blood vessels, as well as a decrease in the production of various inflammatory mediators. Due to this effect, irritation of the nerve pain receptors is minimized. The influence on certain centers of thermoregulation located in the brain allows the latest generation of NSAIDs to perfectly lower the overall temperature.

Indications for use

The effects of NSAIDs are widely known. The effect of such drugs is aimed at preventing or reducing the inflammatory process. These drugs give an excellent antipyretic effect. Their effect on the body can be compared with the effect. In addition, they provide analgesic, anti-inflammatory effects. The use of NSAIDs reaches a wide scale in the clinical setting and in everyday life. Today it is one of the most popular medical drugs.

A positive impact is noted with the following factors:

1. Diseases of the musculoskeletal system. With various sprains, bruises, arthrosis, these drugs are simply irreplaceable. NSAIDs are used for osteochondrosis, inflammatory arthropathy, arthritis. The drug has an anti-inflammatory effect in myositis, herniated discs.
2. Strong pains. The drugs are quite successfully used for biliary colic, gynecological ailments. They eliminate headaches, even migraines, kidney discomfort. NSAIDs are successfully used for patients in the postoperative period.
3. Heat. The antipyretic effect allows the use of drugs for ailments of a diverse nature, both for adults and children. Such medicines are effective even in fever.
4. thrombus formation. NSAIDs are antiplatelet drugs. This allows them to be used in ischemia. They are a preventive measure against heart attack and stroke.

Classification

About 25 years ago, only 8 groups of NSAIDs were developed. Today, this number has increased to 15. However, even doctors cannot name the exact number. Having appeared on the market, NSAIDs quickly gained wide popularity. Drugs have replaced opioid analgesics. Because they, unlike the latter, did not provoke respiratory depression.

The classification of NSAIDs implies a division into two groups:

1. Old drugs (first generation). This category includes well-known drugs: Citramon, Aspirin, Ibuprofen, Naproxen, Nurofen, Voltaren, Diklak, Diclofenac, Metindol, Movimed, Butadion.
2. New NSAIDs (second generation). Over the past 15-20 years, pharmacology has developed excellent drugs, such as Movalis, Nimesil, Nise, Celebrex, Arcoxia.

However, this is not the only classification of NSAIDs. New generation drugs are divided into non-acid derivatives and acids. Let's look at the last category first:

1. Salicylates. This group of NSAIDs contains drugs: Aspirin, Diflunisal, Lysine monoacetylsalicylate.
2. Pyrazolidins. Representatives of this category are drugs: Phenylbutazone, Azapropazone, Oxyphenbutazone.
3. Oxycams. These are the most innovative NSAIDs of the new generation. List of drugs: Piroxicam, Meloxicam, Lornoxicam, Tenoxicam. Medicines are not cheap, but their effect on the body lasts much longer than other NSAIDs.
4. Derivatives of phenylacetic acid. This group of NSAIDs contains funds: Diclofenac, Tolmetin, Indomethacin, Etodolac, Sulindac, Aceclofenac.
5. Anthranilic acid preparations. The main representative is the medicine "Mefenaminat".
6. Propionic acid agents. This category contains many excellent NSAIDs. List of drugs: Ibuprofen, Ketoprofen, Benoxaprofen, Fenbufen, Fenoprofen, Thiaprofenic acid, Naproxen, Flurbiprofen, Pirprofen, Nabumeton.
7. Derivatives of isonicotinic acid. The main medicine "Amizon".
8. Pyrazolone preparations. The well-known remedy "Analgin" belongs to this category.

Non-acid derivatives include sulfonamides. This group includes drugs: Rofecoxib, Celecoxib, Nimesulide.

Side effects

NSAIDs of the new generation, the list of which is given above, have an effective effect on the body. However, they practically do not affect the functioning of the gastrointestinal tract. These drugs are distinguished by another positive point: NSAIDs of the new generation do not have a devastating effect on cartilage tissue.

However, even such effective means can provoke a number of undesirable effects. They should be known, especially if the drug is used for a long time.

The main side effects can be:

• dizziness;
• drowsiness;
• headache;
• fatigue;
• increased heart rate;
• increase in pressure;
• slight shortness of breath;
• dry cough;
• indigestion;
• the appearance of protein in the urine;
• increased activity of liver enzymes;
• skin rash (spot);
• fluid retention;
• allergy.

At the same time, damage to the gastric mucosa is not observed when taking new NSAIDs. The drugs do not cause an exacerbation of the ulcer with the occurrence of bleeding.

Phenylacetic acid preparations, salicylates, pyrazolidones, oxicams, alkanones, propionic acid and sulfonamide drugs have the best anti-inflammatory properties.

From joint pain most effectively relieve medications "Indomethacin", "Diclofenac", "Ketoprofen", "Flurbiprofen". These are the best NSAIDs for osteochondrosis. The above drugs, with the exception of the drug "Ketoprofen", have a pronounced anti-inflammatory effect. This category includes the tool "Piroxicam".

Effective analgesics are Ketorolac, Ketoprofen, Indomethacin, Diclofenac.

Movalis has become the leader among the latest generation of NSAIDs. This tool is allowed to be used for a long period. Anti-inflammatory analogues of an effective drug are the drugs Movasin, Mirloks, Lem, Artrozan, Melox, Melbek, Mesipol and Amelotex.

The drug "Movalis"

This drug is available in the form of tablets, rectal suppositories and a solution for intramuscular injection. The agent belongs to the derivatives of enolic acid. The drug has excellent analgesic and antipyretic properties. It has been established that in almost any inflammatory process, this medicine brings a beneficial effect.

Indications for the use of the drug are osteoarthritis, ankylosing spondylitis, rheumatoid arthritis.
