Abstract

The invention provides a comprehensive utilization method of oily sludge waste heat resources. Oily sludge, anthracite and activated carbon are used as main raw materials, supplemented by additives such as oxidant, calcium oxide, expanded graphite, etc., to prepare oil-coal modified fuel. The invention can reduce the ignition temperature of the modified fuel to about 490°C, and the calorific value still reaches 28000kJ / kg, which is close to anthracite coal. Compared with the direct combustion of oily sludge, the emission of harmful gases in the flue gas is also significantly reduced. The invention is a waste resource utilization technology, and has the advantages of easy availability of raw materials, simple production process, low cost, less exhaust gas emission and the like.

Description

technical field [0001] The invention relates to the field of solid waste treatment and resource comprehensive utilization, in particular to a method for preparing oil-coal modified fuel by using heavy oil waste sludge in oil exploitation. Background technique [0002] Oily sludge is sludge mixed with heavy oil such as crude oil, various refined oils, and residual oil. It is generally produced in the process of oil extraction, refining, storage and transportation, and oily sewage treatment. The composition of oily sludge is complex, except for 10%. In addition to ~50% heavy oil and water, it also contains a variety of additives, such as bentonite, caustic soda, anti-salt shearing agent, anti-salt, anti-temperature and fluid loss reducer, organic salt, inhibiting lubricant, weighting agent, sulfonated phenolic resin, etc. Heavy oil is the difficult part of oily sludge. The Second International Conference on Heavy Crude Oil and Tar Sands (Venezuela, 1982) defined heavy oil as:...
