以海上气田天然气压缩机后置滑油聚结分离系统的现场实际设计运行数据为基础，研究相同气溶胶发尘条件下聚结分离系统中滤芯的过滤性能，考察温度、气量和气溶胶浓度等操作变量对滤芯过滤性能的影响。实验结果表明，滤芯过滤气量越大，过滤效率受浓度及温度影响越小，过滤效率的稳定性越好。过滤气量不变时，温度越低，过滤效率受气溶胶浓度变化的影响越小，运行越稳定；气溶胶浓度越高，过滤效率受温度变化的影响越小，运行越稳定。可为气田实际生产中聚结滤器的运行控制和优化提供参考。

Based on the on-site actual design and operation data of the post installed lubricating oil coalescence separation system of natural gas compressors in offshore gas fields. The filtration performance of the filter element in the coalescence separation system under the same aerosol dust generation conditions is studied， and the influence of operating variables such as temperature， gas volume， and aerosol concentration on the stability of the filter element filtration performance is examined. The experimental results show that the larger the air filtration capacity of the filter element， the less affected the concentration and temperature on the filtration efficiency， and the better the stability of the filtration efficiency. When the amount of filtered gas remains constant， the lower the temperature， the less affected the change in aerosol concentration on the filtration efficiency， and the more stable the operation; The higher the aerosol concentration， the less affected the temperature change on the filtration efficiency， and the more stable the operation. This article can provide references for the operation control and optimization of coalescence filters in actual production of gas fields.
