Filter Separator

Filter separators are usually made of two parts: the first part consists of the filter element and the second part usually includes a vane, cyclone, or wire mesh. As the gas passes through the filter element, the liquid droplets join each other and become larger. After leaving the filter element, it enters the second part where the liquid particles in the previous section are separated. The second part mainly consists of wire mesh or vane. The filter generally has a smaller chamber for the storage of separated liquid. Separation of oil, water, hydrocarbons, and solid particles in the gas stream is necessary for the protection of downstream equipment and can prevent huge damage to equipment such as compressors and valves in downstream units. Because of the very tiny pores in the filter elements, this equipment also acts as a filter for solid particles. An important point in the operation of filter elements is to pay attention to their replacement time. For this purpose, it is necessary for operators to regularly inspect the pressure drop of the filter element before the pressure drop reaches the maximum limit. The use of quick opening closures helps operators to quickly and safely replace filter elements. At the bottom of the filter separators, a small chamber is used to collect liquid droplets and solid particles. This section is equipped with a level indicator (Level Gauge) to inform the operator of the accumulation rate of impurities and to discharge the collection chamber by opening valves.
