GAS CHEMICAL COMPLEX Russian patent published in 2019 - IPC B01D53/00 

FIELD: chemistry.

SUBSTANCE: gas chemical complex providing processing of natural hydrocarbon gases of various deposits can be used in gas industry under conditions of its intensive development. Gas-chemical complex includes a gas processing plant, a gas-chemical plant, a methanol and mineral fertilizer production plant, a natural gas liquefaction plant and a gas transport network which joins the plants to each other, part of the methane-hydrogenous fraction extracted at the gas chemical plant plants and / or part of the hydrogen extracted from the methane-hydrogen fraction is supplied to the methanol synthesis plant of the methanol and mineral fertilizer production plant, CO₂ extracted from natural hydrocarbon gas at a gas processing plant is fed to synthetic gas production plant and / or carbamide synthesis plant of methanol and mineral fertilizers production plant, wherein raw material for methanol synthesis is additionally used is extracted from flue gases of tubular furnaces of plants of gas-chemical plant CO₂, wherein synthetic gas production plant of methanol and mineral fertilizer plant is combined with methanol synthesis unit to provide several process lines using different sources of raw material.

EFFECT: claimed invention solves problem of development of high-efficiency gas chemical complex for processing of natural hydrocarbon gases of one or several deposits of gas producing region with production of maximally diverse assortment of fuel, gas-chemical and chemical commercial products with simultaneous reduction of environmental pollution by carbon dioxide due to its processing into gas-chemical products.
