化学热洗处理含油污泥工程现状及发展

Current Status and Development of Chemical Hot Washing Process for Oily Sludge Treatment Engineering

针对采用“筛选流化—热化学清洗—离心脱水”处理工艺建设的含油污泥处理处置工程,分别调研了A油田、B油田以及C油田含油污泥处理站采用此技术处理含油污泥的现状、效果,指出了该工艺在不同油田应用中存在的问题,并分析总结了原因;提出开发高效、自动化程度高的预处理筛选设备;依托已建含油污泥处理站配套后续电化学、生物或者热解等深度处理技术,实现已建站高效、稳定、达标处理的同时,满足国家日益严格的要求。

Aiming at the oily sludge disposal project constructed upon“screening fluidization-thermochemical cleaning-centrifugal dewatering”treatment,this paper investigates the status quo of sludge treatment stations from three oilfields.The major problems during the application of such technology was summarized.Facing a more stringent requirement from national environmental protection,a pre-filtration device with high efficiency and automation level needs to be deve-loped.In the meantime,a following advanced treatment measures including electrochemical,biological,or pyrolysis was needed after the current treatment scheme,so as to achieve a highly efficient,stable discharge.
