Abstract

The invention discloses an efficient acidic oil sludge decomposing agent, comprising the following component materials in percentages by weight: 1-15% of oxidant, 1-10% of coprecipitator, 5-30% of flocculating agent, 1-10% of surfactant, 0.5-10% of emulsion breaker, 1-10% of acidity regulator and 50-90% of water. The invention further discloses a preparation method of the efficient acidic oil sludge decomposing agent. The preparation method comprises the following steps of: 1, preparing sodium carboxymethylcellulose hydrosol; 2, dissolving all kinds of component materials; and 3, adding the sodium carboxymethylcellulose hydrosol prepared in the first step into the solution obtained in the second step so as to obtain the efficient acidic oil sludge decomposing agent. The invention further discloses application of the efficient acidic oil sludge decomposing agent. The efficient acidic oil sludge decomposing agent disclosed by the invention has the advantages of simple preparation process, low cost and easy industrialization; by means of chemical reaction, surface activation action, flocculation and salting-out emulsion breaking actions, the viscosity of the oil sludge is reduced, the oil phase, the water phase and the sludge phase are effectively separated, and the efficient acidic oil sludge decomposing agent can be used for recovering the crude oil from the oil sludge and quickly treating the petroleum pollution soil.

Description

technical field [0001] The invention relates to the fields of recovering crude oil from oil sludge and environmental protection, in particular to a preparation method and application of a medicament for realizing efficient three-phase separation of oil, water and mud in oil sludge sand. technical background [0002] Oil sludge is a mixture of various forms that may cause environmental pollution when crude oil or refined oil is mixed into mud sand or other media in the process of oilfield development, storage and transportation, and petrochemical industry production, and the oil in it cannot be directly separated and recovered. Oil sludge sand is not sludge in the general concept. These sludges generally have a certain oil content (generally, the oil content in sludge is 10% - 50%, and the water content is 40% - 90%), and the viscosity is large, the particles are fine, The composition is complex and belongs to the multi-phase system, generally composed of oil-in-water, water-...
