Types of combustible gases and their properties

Gazes that can maintain combustion are called combustible. In most cases, they are also explosive, that is, with a large concentration, they can lead to an explosion. Most combustible gases are natural, but there are also obtained by artificially, in the process of certain technological processes.

Methane

This main component of natural gas is burning perfectly, which is widely used in various fields of human activity. With its help, boiler rooms, household gas stoves, cars and other mechanisms work with it. A feature of methane is its lightness. It is lighter than air, so it rises when it leaks, rather than pooling in lowlands like many other gases.

Methane is odorless and colorless, making it extremely difficult to detect a leak. Considering the explosive nature, the gas supplied to consumers is enriched with aromatic additives. As they are used sharp-smelling substances, introduced in very small quantities and giving methane a weak, but unambiguously recognizable aromatic shade.

Propane

It is the second most common combustible gas and is also part of natural gas. Along with methane, it is widely used in industry. Propane is odorless, so in most cases it contains special aromatic additives. Highly flammable and may accumulate in explosive concentrations.

Butane

This natural gas is also combustible. Unlike the first two substances, it has a specific smell and does not need additional aromatization. Butane has harmful effects on human health. In particular, it depresses the nervous system, and with an increase in inhaled volume leads to lung dysfunction.

Types of combustible gases and their properties

coke oven gas

This gas is obtained by heating coal to a temperature of 1,000 degrees without air. It has a very wide composition, from which many useful substances can be isolated. After purification, coke oven gas can be used for industrial needs. In particular, it is used as fuel for individual blocks of the same furnace where coal is heated.

Shale gas

In fact, this is methane, but produced in a slightly different way. Shale gas is released during the processing of oil shale. They are a mineral that, when heated to a very high temperature, releases a resin that is similar in composition to oil. By-product is shale gas.

Petroleum gas

This type of gas is initially dissolved in oil and represents disparate chemical elements. During production and processing, oil is subjected to various influences (cracking, hydrotreating, etc.).d.), resulting in the release of gas. This process takes place directly on the oil rigs, and the classic way to remove it is burning. Those who have ever seen a working oil pumping tower must have noticed a fire torch burning nearby.

Now more and more often petroleum gas is used for production purposes, for example, it is pumped into underground reservoirs to increase internal pressure and simplify the lifting of oil from the well.

Petroleum gas burns well, so it can be supplied to factories or mixed with natural gas.

Blast furnace gas

It is released during the smelting of iron in special industrial furnaces blast furnaces. When using capture systems, blast-furnace gas can be accumulated and used later as fuel for the same furnace or other equipment.
