一种新型卸油计量系统

我国石油工业经过几十年的发展,到今天又进入了一个新的发展时期,过去大的整装油田越来越少,油田发展难度越来越大,从近几年的情况来看,小断块、稠油、高凝油等难采油田越来越多,地面集输系统建设困难重重。为了降低地面建设投资,实现效益最大化,许多油田对一些地处边远且分散的单井、新开发的油井和试验井、远离集输管网或不具备建设管

采用增大凝结液滴方法的锥芯超音速旋流分离装置性能研究

To improve the separation performance of a supersonic gas separation device for the treatment of gas mixture with a single heavy component, a novel structure with shorter settlement distance was constructed and a method of droplet enlargement was applied. A series of experiments were carried out in the improved separation device under various conditions, using air-ethanol vapor as the medium and micro water droplets as nucleation centers. The effects of the inlet pressure, temperature and relative humidity, the swirling intensity, and mass flow rate of water on the separation performance were investigated. The separation was improved by increasing the inlet pressure and relative humidity. With the decrease of swirling intensity and mass flow rate of water, the separation efficiency increased first and then decreased. The inlet temperature had a slight effect on the separation. The results showed that the separation performance was effectively improved using the proposed structure and method, and the best separation in this study was obtained with the ethanol removal rate about 55% and dew point depression 27 K. The addition of water had little pollution to the air-ethanol vapor system since the water carry-over rate was within the range of %-0 in most cases.
