Abstract

The invention relates to the technical field of deodorization, passivation and cleaning and discloses a compound environment-friendly type composition for deodorization, passivation and cleaning and apreparation method and application thereof. The compound environment-friendly type composition for deodorization, passivation and cleaning contains citric acid, urea, sodium p-hydroxybenzoate and secondary deionized water. The invention also discloses the preparation method and application of the compound environment-friendly type composition for deodorization, passivation and cleaning. The cleaning composition disclosed by the invention integrates multiple functions of cleaning and passivation, reduces pollution discharge amount, shortens cleaning time, and has the advantages of environmental friendliness, high efficiency and no corrosion to equipment; and the preparation method is simple.

Description

technical field [0001] The invention relates to the technical field of deodorization and passivation cleaning, in particular to a composite environment-friendly deodorization and passivation cleaning composition and its preparation method and application. Background technique [0002] With the increase in the amount of crude oil processed by refinery and chemical enterprises, the increase in sulfur content and the long-term, full-load operation of the device have resulted in the accumulation of foul-smelling mercaptan, hydrogen sulfide, and ferrous sulfide in the equipment. increase, which poses a great threat to the safety maintenance of the device during shutdown maintenance. At the same time, accidents of ferrous sulfide self-combustion damaging equipment, equipment internal packing, and downtime, stench and odor disturbing environmental protection accidents occurred in various manufacturers, which brought huge losses to the manufacturers. [0003] At present, the deodor...
