Embodiment Construction

[0015] In order to understand the technical solution of the present invention more clearly, the present invention will be further described below in conjunction with specific examples.

[0016] A kind of oil refinery grease cleaning agent of the present invention is made of following components, and the mass ratio of each described component is tripolyglycerol diisostearate 35%, and described trimethylol propane is 65%.

[0017] A preparation method of an oil refinery oil dirt cleaning agent, the preparation method adopts the following steps:

[0018] A is tripolyglycerol diisostearate 35% according to mass percentage, and trimethylolpropane 65% measures raw material, checks mixer;

[0019] B tripolyglycerol diisostearate is added in the blender, and the stirring time is recorded, and the required time from turning on the mixer to the completion of feeding of tripolyglycerol diisostearate is 5-10 minutes;

[0020] C. Slowly add trimethylolpropane into the stirrer and stir, t...

Abstract

The invention discloses a full cleaning agent for an oil refining device and a preparation method of the full cleaning agent. The full cleaning agent is prepared from 30 to 40 percent by mass of tripolyglycerol diisopstearate and 60 to 70 percent by mass of trimethylopropane. The full cleaning agent has the beneficial effects that cleaning capability is strong; the disadvantages of the traditional method, such as incomplete shut-down purging effect, high mechanical cleaning strength and large workload are overcome; the shut-down time is effectively shortened, and consumption of steam, oil and manpower can be remarkably reduced in the case of shut down; the cover opening rate of maintenance equipment is reduced, maintenance cost is lowered, and erosion of high-pressure washing to heat-exchange equipment is avoided; and good environmental friendliness is achieved and difficulty and workload of maintenance field purging can be reduced.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a cleaning agent for oil dirt in an oil refinery. Background technique [0002] With the continuous improvement of clean production and environmental protection requirements of refining and chemical enterprises, oil refining equipment has the characteristics of a lot of grease and high viscosity, and it is difficult to achieve ideal cleaning results by conventional methods. Traditional shutdown and purging are not thorough, and mechanical cleaning is intensive and heavy workload. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a total cleaning agent for oil refining equipment and a preparation method thereof. The total cleaning agent is efficient, easy to clean, and does not corrode equipment. The preparation method of the total cleaning agent is simple. [0004] The technical solu...
