Application of On-line Airtight Micro-pressure Recovery Technology for Oil Tank Volatile Gas
Through the construction of the on-line airtight micro-pressure recovery system of oil tank volatile gas,Shengtuo Union Station could reduce the oil and gas volatile loss and realize the airtight collection and transportation of oil and gas,and the recovery of light hydrocarbon resources.The calculation of respiratory losses for five crude oil tanks of Shengtuo Union Station proved that it was necessary to build an on-line airtight micro-pressure recovery system for volatile gas from oil tanks.The composition,principle,information construction,production operation,protection system and advantages of the system were introduced.The field application situation was described and the effect and benefit analysis were carried out.The system has the characteristics of simple process flow,convenient operation and maintenance,perfect safety protection system,high gas collection efficiency,energy saving and consumption reduction,less investment,fast cost recovery,high degree of automation,wide adaptability,safety and reliability.
