The cyclonic desanding separator is a liquid or gas-solid separation equipment. It uses the cyclone principle to separate solids, including sediment, fracturing sand, rock debris, corrosion chips, scale, and product crystals, from fluids (liquids, gases, or gases-liquid mixture). It will make the production safe with removing efficiently the highly solids content in well stream, after the unit been installed 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.
