含油污泥热解处理技术研究进展

Review on Research Progress of Pyrolysis Treatment of Oily Sludge

原油的开采和运输过程中会产生大量含油污泥,为了达到资源化,无害化的目标,需要对含油污泥进行处理来达到节约资源保护环境的目的。含油污泥等固体废弃物可以通过热解、填埋、焦化、固化、微生物处理等多种处理技术。含油污泥热解处理技术可以使含油污泥中的原油成分再次利用,不造成资源浪费,并且对含油污泥处理彻底。本文主要讲解热解含油污泥技术,通过改变反应温度、反应时间、升温速率、控制氮气流量和添加催化剂来对含油污泥资源化回收利用进行总结。

A large amount of oily sludge will be generated in the process of crude oil exploitation and transportation.In order to achieve the goal of resource recovery and innocuity,oily sludge needs to be treated to achieve the purpose of resource conservation and environmental protection.Oily sludge and other solid wastes can be treated by pyrolysis,landfill,coking,curing,microbial treatment and other treatment technologies.The pyrolysis treatment technology of oily sludge can reuse the crude oil in oily sludge,avoid resource waste,and thoroughly treat oily sludge.This paper mainly explains the pyrolysis oily sludge technology,and summarizes the recycling and utilization of oily sludge by changing reaction temperature,reaction time,heating rate,controlling nitrogen flow and adding catalyst.
