The cyclonic desanding separator is a liquid-solid separation equipment. It uses the cyclone principle to separate solids, including sediment, rock debris, metal chips, scale, and product crystals, from fluids (liquids, gases, or gases-liquid mixture). It is used for removing those very fine particles (5 microns @98%) from the condensate which is separated from gas-liquid separator in which those solids went to the liquid phase and caused the blockage and erosion in the production system. Combined with SJPEE’s unique patented technologies, the filter element is made of high-tech ceramic wear-resistant (or called highly anti-erosion) materials or polymer wear-resistant materials or metal materials. High-efficiency solid particle separation or classification equipment can be designed and manufactured according to different working conditions, different fields and user requirements.
