GAS-CHEMICAL CLUSTER Russian patent published in 2018 - IPC B01D53/00 

FIELD: mining.

SUBSTANCE: invention relates to the rational use of natural resources and development of marginal regions and can be used in gas production, gas processing, gas-chemical and other industries. Gas-chemical cluster includes a gas production unit, a gas processing unit, a gas-chemical unit and a gas transporting link. Extracted natural gases with an ethane content of less than 3–4 % by volume are combined into a commercial fuel gas stream. Extracted natural gases with an ethane content of more than 3–4 % by volume are combined in a stream of ethane-containing hydrocarbon gas entering gas processing plants or channeled under pressure into a separate gas pipeline corridor of the gas pipeline's main gas pipeline. At the enterprises of the gas processing unit, the ethane-containing hydrocarbon gas stream is subjected to fractionation with separation into methane, ethane, propane and a wide fraction of light hydrocarbons. At the same time methane is fed to the gas production unit for mixing with the flow of commodity fuel gas. Ethane, propane and a wide fraction of light hydrocarbons are sent under pressure to separate gas pipelines in the corridor of gas pipeline main pipelines or used as raw materials in pyrolysis units of the gas-chemical unit. After the pyrolysis furnaces the reaction products are subjected to separation into ethylene and propylene, fed further as feedstock to petrochemical synthesis units of the gas chemical unit.

EFFECT: claimed invention ensures the optimal utilization of extracted natural gas and the complex economic development of several regions.
