高含铁清罐原油脱铁净化技术的工业实践OA

The industrial application of the SOTU(Slop Oil Treatment Unit)technology is introduced to solve the challenge of high-iron-content slop oil generated during mechanical cleaning of storage tanks in an enterprise.Compared with the problems of catalyst metal poisoning and equipment corrosion caused by conventional direct blending methods,SOTU technology enables efficient removal of iron impurities and effective three-phase separation of oil,water,and solids.Industrial implementation results demonstrate that the treated oil contains less than 0.9%water and less than 0.1%ash,making it suitable for direct re-refining.The oil concentration in the separated wastewater is below 110 mg/L,complying with municipal sewage discharge standards.The solid residue has a moisture content of less than 21%and is designated for off-site disposal.The iron removal efficiency exceeds 75%,yielding an annual comprehensive economic benefit of over 10 million yuan.This technology provides a reliable and economically viable solution for the resource recovery and treatment of waste oil in petroleum refining facilities.
