Embodiment Construction

[0008] The present invention will be further described below:

[0009] The method is carried out on the basis of the oily waste treated with water-containing sludge. First, the oily waste is separated at normal pressure and at a temperature of 0 to 50°C by means of an oil-water separation pump. Add 0.03-0.05 parts of flocculant in the water, use the principle of different specific gravity between the separated water and the separated flocculent organic matter, use the pump to extract the oil, and the result is flocculent organic matter, use oil twister to grind and filter The above-mentioned flocculent organic matter is ground and filtered by the machine. After filtering, the particles with a mesh size of 50 to 100 are put into a kettle-type tank, and the particles with a mesh size of 0 to 50 are put into an atmospheric furnace, and then all are heated at a temperature of 100 to 300°C. Carry out heating treatment; the flocculent organic matter after the heating treatment in th...

Abstract

The preparation method of fuel oil by utilizing oil sludge is characterized by that firstly, using oil-water separation pump to separate effluent oil reject under the condition of normal pressure and0-50 deg.C; adding 0.03-0.05 portion of flocculant in separated portion of oily material, and using pump to extract petroleum, then using oil grinding mill and filter to grind and filter the flocculent organic material, and placing the filtered material whose grain size is 50-100 meshes into still type tank and placing the filtered material whose grain size is 0-50 meshes into normal pressure furnace to make heating treatment at 100-300 deg.C; finally, respectively placing the treated flocculent organic materials into normal pressure dispersion distillation tank and normal pressure dispersiondistillation tower, under the catalysis of defoaming agent making reaction to form fuel oil obtained by blending bas oil with heavy diesel oil.

Description

Technical field: [0001] The invention relates to a method for preparing fuel oil that can be combusted from sludge produced from oily sewage in oilfields, and belongs to a method for preparing fuel oil prepared by processing and blending sludge. Background technique: [0002] At present, with the gradual deepening of oil field development, especially since polymer flooding and ASP flooding, waste oil and sludge wastes are increasing, the chemical composition is also relatively complex, and the oil content is very small. After cleaning the operation tank , the recycling team tends to recycle the waste as oil, and returns it to the operation tank through the pipeline for recycling, which will inevitably cause a vicious cycle of sludge impurities in the sewage treatment system, which not only increases the difficulty of sewage treatment, but also affects the quality of effluent water , and even cause adverse consequences of blocking the formation; sometimes it is necessary to r...
