Method for treating oily sludge by using corex furnace

Abstract

The invention discloses a method for treating oily sludge by using a corex furnace. The method comprises the steps that firstly, the oily sludge is collected, the oily sludge and an emulsifying viscosity reducer are added into a mechanical stirring device according to the mass ratio of 20 to 1 for stirring for 30 minutes, so that the viscosity of the oily sludge is reduced, then the oily sludge enters an oily sludge tank, finally, the oily sludge with reduced viscosity is sprayed into an arch top area of the gasification furnace through a pressurization pump and a liquid injection nozzle for combustion decomposition, and the spraying pressure at the position of the liquid injection nozzle is 2 atmospheres; and the oily sludge is converted into coal gas for secondary utilization after beingsubjected to decomposition at the arch top of the corex furnace, and part of the material which cannot be decomposed enters furnace slag and is used as a building material for secondary utilization.

Description

technical field [0001] The invention relates to a method for treating oily sludge with an Ouye furnace. Background technique [0002] With the development of the petroleum industry, the environmental pollution problem of the petroleum industry is also becoming more and more serious. Among them, the treatment of oily sludge is a big problem in the treatment of solid waste in the petroleum industry. Taking oil exploration and development as an example, its output is 0.5% to 1% of crude oil output. Especially, many large oil fields in my country have entered the middle and late stages of development, and the output of oily sludge and oil sands is greater than this figure. The oil trap bottom sludge, flotation tank scum, and crude oil tank bottom sludge produced in the sewage treatment plant are commonly known as "three muds". It is estimated that my country's annual output of oily sludge is nearly 3 million tons, and the annual waste of oil resources can up to about 600,000 ton...

AI Technical Summary

Problems solved by technology

[0003] A large amount of oil sludge discharged every year not only occupies a large amount of land, wastes precious crude oil resources, but also encroaches on a large amount of arable land

The composition of oily sludge is complex, which contains a large number of toxic substances such as pathogenic bacteria, parasites, and dioxins, as well as heavy metals such as copper, chromium, zinc, and mercury, and refractory substances such as radionuclides, which pollute the surrounding environment , not only seriously affect the normal production of the oil field, but also cause harm to the normal life of the staff and nearby residents

At present, the treatment technology of oily sludge is relatively backward. In order to solve the discharge problems such as reasonable disposal of oily sludge and environmental compliance, various petrochemical enterprises, research institutes and related universities have carried out some basic research experiments on oily sludge, but in actual industry There are still some problems in the application, and the truly mature process technology has not yet been realized
