In order to meet daily oil discharge, the gas field stations in sulfur-containing oil and gas fields generally choose to use the gravity flow to discharge the waste oil from each device point to the pit recovery tank. When the recovery tank reaches the upper limit level, the waste oil from the recovery tank is transported to the downstream storage tank by the way of manualoil pressurization.This method has such issues as longoperation time, highfrequency, andseriouspotentialsafetyhazard. This paper mainly introduces the use of the automatic oil pressurizingoperationinstead of manual method, so as to reduce the frequency ofgettinginto the pitby staff, to reduce the risk.
