2、目前对过滤器的气液分离性能研究较少b为此, 以癸二酸二辛酯( DOS)为实验介质,采用称重法对天然气过滤器的气液分离性能进行了实验研究b主要考察滤芯表面滤速a气体含液浓度和液滴平均粒径对滤芯压降及过滤效率等方面的影响b结果表明: 气液分离时滤芯的压降变化与气固分离时有较大的不同,气液过滤开始的一段时间里,滤芯的压降缓慢升高, 达到临界值后压降迅速升高到某一数值,之后压降基本保持稳定; ! 气液分离过程中,滤芯具有较好的聚结性能, 聚结得到的液体所占比例较大; 丝网对气流中夹带的液滴有一定收集作用, 但捕获的液滴所占比例较小; #随着滤芯表面滤速的增加, 滤芯的气液分离性能也随之提高; 液滴粒径
