Abstract

The invention discloses an oil sludge demulsifier and a preparation method thereof. The oil sludge demulsifier comprises the following components: trisodium nitrilotriacetate, ethylenediamine tetraacetic acid, an emulsifier, a penetrating agent, inorganic salt, diatomite, alkali and water. The oil sludge demulsifier comprises the following components in percentage by mass: 6.5%-12% of trisodium nitrilotriacetate, 10%-15% of ethylenediamine tetraacetic acid, 3.5%-8% of an emulsifier, 20%-40% of a penetrating agent, 1.5%-5% of inorganic salt, 5%-15% of diatomite, 0.5%-5% of alkali and the balance of water. The oil sludge demulsifier disclosed by the embodiment of the invention is simple in proportioning process, reasonable in proportioning components and convenient to prepare and operate. Moreover, the oil sludge demulsifier is used for oil sludge treatment, and the effective utilization rate of petroleum hydrocarbon is greatly increased, so that oil sludge recycling is improved, and technical reserves are provided for soil remediation in the future.

Description

technical field [0001] The embodiment of the present application relates to the technical field of the petroleum industry, in particular to an oil sludge demulsifier and a preparation method. Background technique [0002] Oil sludge is a large amount of black solid and semi-solid waste containing oil that will be produced in the process of oil extraction, gathering and transportation, refining and oily sewage treatment. The main components of oil sludge are oil, mud and water. In addition to a large amount of aged crude oil, waxy, and colloidal substances, the oil sludge contains a large amount of toxic and harmful substances such as benzene series, phenols, polychlorinated biphenyls, and dioxins, and the oil sludge also contains a large number of pathogenic bacteria and parasites. If it is not treated reasonably and effectively, it will not only waste oil resources, but also cause serious pollution to the environment. [0003] At present, the technologies for sludge treat...
