What substances are part of the natural gas
at 80-98% natural gas consists of methane (CH4).It physicochemical properties determine the characteristics of methane gas.Apart from methane in natural gas composition are compounds of the same structural type - ethane (C2H6), propane (C3H8) and butane (C4H10).In some cases, small quantities, 0.5 to 1% of the natural gas found: pentane (S5N12), hexane (S6N14), heptane (S7N16) octane (S8N18) and nonane (S9N20).Also
gas includes compounds sulfide (H2S), carbon dioxide (CO2), nitrogen (N2), helium (He), water vapor.The composition of natural gas depends on the characteristics of the fields, where it is mined.Natural gas produced in pure gas fields, consists mainly of methane.
Features components of natural gas
All chemical compoun
ds that are part of the natural gas, possess a number of properties that are useful in various spheres of industry and everyday life.
methane - a flammable gas is colorless and odorless, it is lighter than air.It used in industry and everyday life as fuel.Ethan - flammable gas is colorless and odorless, it is slightly heavier than air.Basically, ethane prepared from ethylene.Propane - poison gas is colorless and odorless.He was on the properties similar butane.Propane is used, for example, during welding, the processing of scrap metal.Liquefied propane and butane lighters and fill with gas cylinders.Butane is used in refrigeration.
pentane, hexane, heptane, octane and nonane - colorless liquid.Pentane and hexane in small amounts are included in motor fuels.Hexane was used as the extraction of vegetable oils.Heptane, hexane, octane and nonane are good organic solvents.
Hydrogen sulfide - a poisonous, colorless heavy gas has an odor of rotten eggs.This gas even in small concentrations causes paralysis of the olfactory nerve.But due to the fact that hydrogen sulfide has good antiseptic properties, it is used in small doses in medicine for hydrogen sulfide baths.
Carbon dioxide - non-flammable, colorless and odorless gas with a sour taste.Carbon dioxide is used in the food industry: in the production of carbonated beverages for the saturation of carbon dioxide for freezing, refrigerating cargo in transit, etc.
Nitrogen - a harmless gas is colorless, odorless and tasteless.It is used in the production of fertilizers used in medicine, etc.
Helium - one of the lightest gases.It is colorless and odorless, non-flammable, non-toxic.Helium is used in various industries - welding, for cooling nuclear reactors, filling stratosphere.
