Development and Application of a New Type of Inlet Filter Separator
In the dehydration process of natural gas field,the natural gas treatment system adopting triethylene glycol dehydration process needs to remove solid impurities,heavy hydrocarbon components and free water droplets through the inlet filter separator to reduce the downstream dehydration load.In daily production,the traditional inlet filter separator has problems such as unstable liquid level in the chamber,freezing and blocking of pipeline throttling,and natural gas flowing into the flare tank.The main reasons for the unstable liquild level of the traditional inlet filter separator are the large pressure difference of the liquid level regulating valve and the small volume of the liquid collecting chamber,are a new inlet filter separator device is innovatively proposed to solve this problem.The on-site field application shows that the device can effectively increase the back pressure of the liquid level regulating valve of the inlet filter separator,buffer the impact of the upstream liquid to ensure the stability of its liquid level,reduce the venting of the flare,and achieve good results in energy conservation and emission reduction.It can be widely used in the triethylene glycol dehydration process system of natural gas fields.
