Active matter and solvent bonded degumming oil displacement agent, method for preparing same and application of active matter and solvent bonded degumming oil displacement agent to chemical-process oil production

Abstract

The invention discloses an active matter and solvent bonded degumming oil displacement agent, a method for preparing the same and application of the active matter and solvent bonded degumming oil displacement agent to chemical-process oil production. The active matter and solvent bonded degumming oil displacement agent comprises surfactants, fatty alcohol, dichloromethane, benzyl alcohol, ethyleneglycol, ether of the ethylene glycol or poly-glycol and ether of the poly-glycol, water and the like. The method includes steps of (i), preparing the surfactants; (ii), preparing products; (iii), diluting the products. The active matter and solvent bonded degumming oil displacement agent, the method and the application have the advantages that the active matter and solvent bonded degumming oil displacement agent is applicable to scrubbing or is applicable to being sprayed on paint and printing ink by the aid of mist spray appliances or can be used for 'illegal advertisements' adhered by adhesive, is high in soaking and melting speed, large in applicable area, low in cost and free of environmental pollution, is harmless on the health of staffs and is an affordable 'illegal advertisement' cleaning agent, and thorough scrubbing effects can be realized by the active matter and solvent bonded degumming oil displacement agent; the active matter and solvent bonded degumming oil displacementagent further can be used for removing heavy grease stain of range hoods and is applicable to exploiting thick petroleum ore deposits with high gum contents.

[0002]Street "wild advertising", commonly known as urban "psoriasis", not only pollutes and destroys the city appearance, affects the view, but also misleads and confuses the citizens, which is extremely harmful big

Most of the "wild advertisements" are either sprayed with paint or pasted on conspicuous places such as walls, advertising carriers, and bus stop signs with glue. Detergents, decontamination powders, etc. are powerless

Although organic solvents can soak and dissolve paint in theory, organic solvents are generally more toxic. After volatilization and diffusion, they will seriously pollute the environment and cause great harm to the health of cleaning personnel. Moreover, the price of organic solvents is relatively high. "The cost is too high, and it is actually impossible to implement. At the same time, although organic solvents can dissolve colloids, the dissolved dirt has strong adhesion and is not easy to detach from the substrate, and it is still difficult to completely remove it.

The active substance type scavenger cannot dissolve the colloid and cannot be used alone as a scavenger for the colloid

In addition, at the beginning of this century, the simple surfactant sodium petroleum sulfonate was used as the oil displacement agent for poor residual oil recovery in the field of oil exploitation. Therefore, the oil layer at this stage is basically high in glue and asphalt content, and the molecular weight is too large to be viscous and difficult. Poor extraction effect
