METHOD FOR COLLECTING AND PREPARING HYDROCARBON GAS FOR TRANSPORTING Russian patent published in 2017 - IPC B01D53/02 B01D53/26 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the collection and treatment of natural hydrocarbon gas by the absorption drying technology, and can be used in field preparation processes for transporting gas fields products. According to the method for collecting and preparing hydrocarbon gas to the transporting by the absorption drying method for gas from the wells cluster of the plants of the gas preliminary preparation plants, the primary and additional separation is carried out, absorbent is introduced into gas, absorbent is withdrawn from gas. After that gas is withdrawn from gas preliminary preparation plants and transported to plant of complex gas preparation, secondary and additional secondary separation of gas from gas preliminary preparation plants is carried out. Gas from the wells cluster of the gas complex preparation plant passes the separation and the additional separation, the absorbent is introduced into the gas, the absorbent is withdrawn from the gas, gas is compressed and cooled, gas of installation of gas complex preparation with gas of gas preliminary preparation plants is mixed. After that mixed gas is compressed and cooled, absorbent is introduced into mixed gas, absorbent is withdrawn from gas, mixed gas is withdrawn from the plant. At that gas of gas preliminary preparation plants after removal of absorbent from it is compressed and cooled, after transportation and separation the gas of gas preliminary preparation plants is introduced into gas of complex preparation plant after compression and cooling.

EFFECT: prevention of gas production due to mutual effect of wells and provision of efficient use of formation energy of gas pool.
