Embodiment Construction

[0019] In order to understand the technical solutions of the present invention more clearly, the present invention will be further described below with reference to specific embodiments.

[0020] The ethylene cracking cleaning agent of the present invention is made of Tween 80, citric acid, sodium persulfate, potassium permanganate and secondary deionized water, wherein the mass percentage of each component is Tween 80 15-25%, citric acid 0.4-0.6%, sodium persulfate 15-25%, cinnamaldehyde 4-6%, potassium permanganate 1-2%, secondary deionized water 40-50%, the aforementioned The total amount of each component is 100%.

[0021] Preferably, the mass percentage of each component is Tween 80 20%, citric acid 0.5%, sodium persulfate 20%, cinnamaldehyde 5%. Potassium permanganate 1%, secondary deionized water 46.5%.

[0022] A preparation method of an ethylene cracking cleaning agent, characterized in that: the preparation method adopts the following steps:

[0023] A is Tween 80...

Abstract

The invention discloses an ethylene cracking and cleaning agent and a preparation method thereof. The ethylene cracking and cleaning agent is prepared from Tween 80, citric acid, sodium persulfate, potassium permanganate and secondary deionized water, wherein the percentage by weight of each component is as follows: the Tween 80 accounts for 15-25%, the citric acid accounts for 0.4-0.6%, the sodium persulfate accounts for 15-25%, cinnamaldehyde accounts for 4-6%, the potassium permanganate accounts for 1-2%, and the secondary deionized water accounts for 40-50%. The ethylene cracking and cleaning agent disclosed by the invention has the beneficial effects of high efficiency, no toxicity, no corrosion, no secondary pollution and fast passivation action against ferrous sulfide, and can effectively prevent spontaneous combustion of the ferrous sulfide; the using method is simple, large process adjustment is not required, and only small alteration is needed on the basis of an existing device; the ethylene cracking and cleaning time is 8-10 hours, more than 90% of the ferrous sulfide can be removed, and the shutdown time of the device is correspondingly reduced; a protective film can be formed on the surface of metal after cleaning, so that the surface of the metal can be effectively prevented from being further corroded; and a mixed solution after being treated by the cleaning agent can be directly discharged without the impact on a sewage treatment field.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to an ethylene cracking cleaning agent and a preparation method thereof. Background technique [0002] With the progress of the overall technology of China's ethylene cracking unit, the scale of my country's ethylene cracking unit has been continuously expanded, and the start-up period has been continuously extended. But at the same time, it also puts forward higher requirements for the safety of the device during shutdown and maintenance. In particular, how to prevent the spontaneous combustion of ferrous sulfide in the components and fillers in the quenching oil tower and the quenching water tower without prolonging the downtime for maintenance, so as to achieve the purpose of protecting equipment and eliminating potential safety hazards, has become our shutdown maintenance. a major problem. SUMMARY OF THE INVENTION [0003] In order to overcome the above-mentioned def...
