DiSep^® technology is based on the principles of nonlinear electric field theory- electrophoresis and dielectric electrophoresis, and the innovative technology optimizes the electromagnetic field gradient to strengthen adsorption, which can more effectively remove catalyst fine powder and metal impurities from heavy oil, and the solid content of the separated oil slurry (clarified oil) can reach below 50ppm for a long time according to customer needs, which meets the conditions of high value-added chemical raw materials.
