Problems solved by technology

[0003] At present, the commonly used cleaning agents for such oily dirt are alkaline aqueous solution, but most of them are poor in removing mineral oil dirt, so they can only be used as daily degreasers; organic solvents, commonly used petroleum solvents, halogenated hydrocarbon solvents and alcohol solvents etc. Although it has good solubility to oil stains, it is flammable, volatile and toxic, so it should be used with caution
Surfactant solution has unique functions of reducing surface tension, wetting and penetrating, emulsifying, dispersing and solubilizing, etc. It has good ability to remove liquid oil stains, but poor ability to remove solid oil stains

Embodiment

[0028] Embodiment: A kind of preparation method of high-efficiency pollution-free ethylene oil-based cleaning agent, adopts following steps to make:

[0029] A Weigh the raw materials according to the mass ratio of 35% tetramethoxypropane, 35% dimethoxyethane, 25% diethylene glycol octyl ether, 2% surfactant, 2% sodium carbonate, and 1% sodium silicate. use;

[0030] B uniformly mix the tetramethoxypropane, dimethoxyethane and diethylene glycol octyl ether taken by weighing;

[0031] C adds the weighed surfactant into the mixed solution prepared in step B and mixes evenly;

[0032] D Add the weighed sodium carbonate and sodium silicate into the mixed solution prepared in step C in sequence, stir evenly, and mix well to prepare a high-efficiency and pollution-free vinyl oil-based cleaning agent.

[0033] Further, the surfactant is a mixture of fatty alcohol polyoxyethylene ether and sorbitan oleate, wherein in the mixture, fatty alcohol polyoxyethylene ether accounts for 65% ...

Abstract

The invention relates to a high-efficiency pollution-free ethylene oil-base detergent which is composed of the following components in percentage by mass: 30-45% of tetramethoxypropane, 30-45% of glycol dimethyl ether, 20-35% of diethylene glycol octyl ether, 1-5% of surfactant, 2-5% of sodium carbonate and 1-3% of sodium silicate. The detergent has the advantages of high cleaning power, no generation of wastewater or waste liquid, no problem in wastewater treatment, less equipment corrosion, lower load for operating personnel, high efficiency, no harm to the human body, no corrosion to the equipment, no secondary pollution, simple application method and no need of great technique regulation; and the cleaning waste oil can be mixed with heavy oil to perform reprocessing and reutilization.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a high-efficiency and environment-friendly cleaning agent with high efficiency, no pollution, simple operation process, and reusable waste oil after cleaning. Background technique [0002] With the progress of the overall technology of my country's ethylene plants, the scale of my country's ethylene plants has been continuously expanded, and the start-up period has been continuously extended. At the same time, higher requirements have been put forward for the safety of plant shutdown and maintenance. As we all know, in the cracking process, a certain amount of ethylene oligomers will be produced. These ethylene oligomers contain unquenched free radicals. At the same time, the quenching oil system has complex and heavy components, which will accumulate heavy components, polymers, coke powder and other substances in the packing or flow dead zone. [0003] At present, the commonly used cleaning ...
