Abstract
The invention discloses a closed recovery system and method for volatile organic compounds in a gas gathering station, and the method comprises the following steps: firstly, a gas gathering station dehydration skid tail gas treatment system adopts a gas-liquid separation and pressurization combined triethylene glycol dehydration device tail gas treatment total process to treat the dehydration skid tail gas, and then enters a produced water flash evaporator recovery system; dehydration skid tail gas entering the produced water flash steam recovery system is separated through a first-stage inlet separator, separated gas enters a first-stage outlet separator, separated sewage enters a flash evaporation liquid separation tank, a dehydration skid flash evaporator and a produced liquid buffer tank are added into the first-stage outlet separator for gas feeding, then separation is conducted, and the separated gas enters a second-stage outlet separator. The separated sewage enters a flash evaporation liquid separation tank, the separated gas enters a multi-stage outlet separator and is emptied to enter an emptying liquid separation tank and the multi-stage outlet separator for gas-liquid separation, the separated sewage enters a produced liquid buffer tank, and the separated gas enters a raw material gas pipe network; according to the whole system, organic matter volatile gas is recovered while the organic matter volatile gas is treated according to standard requirements, and precious oil and gas resources are saved.
