卧式气-油-水三相分离器工程设计探讨

On engineering design of horizontal gas-oil-water three-phase separator

卧式气-油-水三相分离器在煤化工领域的应用日益广泛,其性能的优劣、工作状态的稳定、效率的高低直接影响着整个装置的处理能力与稳定生产。为了完成对某煤化工典型装置的三相分离器的详细设计,分别按照传统行业标准及传统自由沉降理论2种方法进行了对比设计。由结果可知:传统行业标准并不适用于该装置三相分离器的设计,而根据自由沉降理论,对雷诺数、沉降速度、横向运行距离等参数进行了反复校核所得到的计算结果较为准确。对设计过程中遇到的问题与难点进行了剖析,最终确定了适宜的设计参数,按照该方法设计的三相分离器现场应用效果良好。文中也对未来的气-油-水三相分离器设计过程提出了建议。

Horizontal gas-oil-water three-phase separator is widely applied in the field of coal chemical industry, the pros and cons of its performance, stability and efficiency of the working state have a direct effect on the processing capacity and stability of the entire unit production. In order to complete the detailed design about three-phase separator of a typical device for coal chemical industry, the comparative design was performed according to both the traditional national standard calculation and the traditional free settling theory respectively. The result showed that the traditional national standard calculation was not applicable to the design of this typical device, however the result was relatively accurate when design process was carried out according to the three settling theory, by which Reynolds number, sedimentation velocity, lateral operation distance and other parameters were calculated and checked over and over again. The problems and difficulties were analyzed, and the appropriate design parameter was determined finally. And for the future gas-oil-water three-phase separator design process was proposed.
