What can be manufactured from natural gas ? | |
Natural gas burns very well. Therefore, it is mostly used for generating electric or thermal energy. However, it can also be used to make fertilizers, fuel, paint, and many other items useful. | |
Green fuel | |
About one half of gas supplies in Russia fall on energy companies and public utilities. Even if there are no gas-powered stoves or water heaters in the house, electricity and hot water are most likely produced with the use of natural gas. Natural gas is the most environmentally friendly hydrocarbon fossil fuel. Only water and carbon dioxide result from its combustion, while the combustion of oil products and coal results in soot and ash. In addition, the emission of the greenhouse carbon dioxide while the combustion of natural gas is the lowest, due to which it is called “green fuel”. Gas is the most popular fuel in the power industry of large cities for its high environmental performance. |

Methanol (CH3OH) is produced from natural gas under a scheme similar to the Fischer-Tropsch process. It is used as an agent for preventing hydrate plugs that are formed in pipelines at low temperatures. Methanol can also become a feedstock for manufacturing more complex chemical substances: formaldehyde, insulation materials, varnishes, paints, glues, fuel additives, and acetic acid. Mineral fertilizers are produced from natural gas by means of several chemical conversions. At the first stage, it’s ammonia. The process of ammonia production is similar to the gas-to-liquid process, but different catalysts, pressure, and temperature are required. Ammonia as such is a fertilizer; it is also used as a coolant in refrigerating units and as a feedstock for production of nitrogen compounds, such as nitric acid, ammonia nitrate, and carbamide |

How ammonia is produced |
|
Natural gas is first cleaned from sulfur, and then mixed with heated water vapor and supplied to the reactor, where it passes through catalyst beds. This stage is called primary reforming or gas-vapor conversion. A gas mixture composed of hydrogen, methane, carbon dioxide (СО2), and carbon oxide (СО) exits from the reactor. Then, this mixture is sent to secondary reforming (gas-vapor conversion), where it is mixed with atmospheric oxygen, vapor, and nitrogen in proper proportions. At the next stage, CO and CO2 are removed from the mixture. Then, a mixture of hydrogen and nitrogen is sent to ammonia synthesis. | |
Significant volumes of gas are also used in the metallurgic industry. But here, natural gas is also used as an energy source for heating blast furnaces. | |
Compressed gas is produced at CNG filling stations by the compression of natural gas, supplied via the gas pipeline, to 20–25 MPa (200–250 atm). | |
Liquid hydrocarbons were first produced from synthesis gas by German chemists Franz Fischer and Hans Tropsch in 1923. They used coal as a source of hydrogen at that time, though. Currently, different modifications of the Fischer-Tropsch method are applied in many marketed processes for conversion of gas into liquid hydrocarbons. |
