Embodiment 1

[0046]Oily sludge modification: Mix and stir oily sludge with a water content of 60% and a modifier, specifically: mix and stir oily sludge with a water content of 60% and an oily sludge modifier to obtain a mixture, and the oily sludge accounts for the modified The mass percentage of oil sludge is 70wt%, and the mass percentage of the oil sludge modifier in the modified oil sludge is 30wt%.

[0047] Among them, the oil sludge modifier is used to change the component structure of the oily sludge and reduce the activation energy. When the modified sludge clean fuel is burned, the sludge modifier plays a role in eliminating smoke.

[0048] The oil sludge with moisture content is directly mixed with the oil sludge modifier to make the modified oil sludge. The modification process is that the petroleum components in the oil sludge are polymerized to cause new groups in the flame retardant long-chain compounds such as asphaltene and colloid. Reduce the activation energy and convert...

Abstract

The embodiment of the invention discloses a modified oil sludge clean fuel and a preparation method of the modified oil sludge clean fuel. According to the method, oil sludge and an oil sludge modifier are mixed and stirred, the activation energy of the oil sludge is reduced, and petroleum coke powder, biomass fuel, a desulfurizing agent and an adhesive are added to the uniformly stirred oil sludge. The petroleum coke powder improves the combustion heat value of the modified oil sludge; pulverized biomass improves the burn-off rate of the modified oil sludge fuel; the desulfurizing agent removes sulfide in the fuel and reduces the pollution to the air during the burning of the fuel; the adhesive is beneficial to the increasing of the molding rate of the fuel. The modified oil sludge clean fuel can be sufficiently burnt in a combustion boiler, the combustion heat value is guaranteed, the molding rate of the fuel is high, and both flue gas emission and ash emission reach the standard.

Description

technical field [0001] The application relates to the technical field of petroleum sludge treatment, in particular to a modified oil sludge clean fuel and a preparation method of the modified oil sludge clean fuel. Background technique [0002] Oilfield oily sludge (hereinafter referred to as oily sludge) is a kind of waste produced in the production process of oilfields. It has a wide range of sources and a huge amount. Oily sludge refers to oily sludge produced in oilfield production activities, mainly from workover operations, crude oil gathering and transportation and processing processes. The mixture of mud, sand and water polluted by crude oil and other organic substances, the sludge of various oil tanks, the sludge produced by production and accidents, and the bottom sludge and scum produced by oilfield produced water treatment facilities. [0003] The physical and chemical composition of oil sludge is very complex. It not only contains a large amount of crude oil, as...
