摘要：Oil concentration in gas varies widely and has a serious effect on filters in natural gas pipelines. In order to study effects of oil concentration in gas on pressure drop and liquid content of filters and the feasibility of applying different filter layers for different concentrations, a filter evaluation device was used to study pressure drop with different filter layers under different oil concentrations (0.07~1.00 g·m^-3). The results show that oil concentration in gas can change channel numbers, which has significant effects on channel pressure drop of filters. The channel number and liquid contents in each layer increase with the increase of oil concentration, and the channel formation time decreases. Furthermore, the channel pressure drop increases nonlinearly with the increase of oil concentration in gas, while whether the liquid content in filters reaches saturation is a key factor in sharp rise of channel pressure. In addition, filter layer affects the growth trend of pressure drop by changing channel numbers. Increase of filter layer number can decrease channel pressure drop when oil concentration in gas is 0.2~0.4 g·m^-3. A model of relationship among oil concentration in gas, filter layer and channel pressure drop can help the optimization of filter structure and prediction of channel pressure drop under different oil concentrations.
