Description
Technical field
The present invention relates to a kind of recirculated water and peel off cleansing composition and using method thereof.
Background technology
Water resource has become the key factor of restriction petroleum chemical enterprise development, and water conservation is very urgent. Circulation is one and uses water rich and influential family, and at present, improving cycles of concentration is recirculated water water-saving method the most direct, maximally effective. But, if circulation leaked substance, it is necessary to replacing with substantial amounts of fresh water, not only waste substantial amounts of fresh water, and the consumption of water treatment agent also rolls up, cost would increase substantially.
Oil leak is a kind of situation that petroleum chemical enterprise's circulation often occurs. Oil leak in recirculated water show themselves in that one be system oil content increase, two is that bacterial number exceeds standard significantly. Its harm have following some: one is provide nutrition for bacterial growth, makes antibacterial raised growth, and float in the antibacterial of growth and recirculated water and material form biological clay, are deposited in heat transmission equipment, affect heat transfer effect, cause corrosion; Two is that the material of leakage causes that antibacterial lost efficacy, and material directly reacts with chlorine and non oxidizing bactericide, affects the effect of antibacterial, so that antibacterial raised growth; Three is some material, such as heavy oil spill, adheres on tube wall, cooling tower or heat transmission equipment, impact heat transfer and cooling; Four is antibacterial raised growth, and inhibition, antisludging agent are had Degradation, thus the inhibition of influential system and scale inhibition effect.
At present, the method solving the leakage of circulation oil product mostly is the operation of low cycles of concentration, large excretion and large complement, adds simultaneously and peels off the various adverse effects that abluent reduction oil leak brings to circulation and heat exchanger surface. Low cycles of concentration operation can waste a large amount of fresh water, the oily substance of residual in circulation, brings adverse effect, circulation treatment effect to can not get ensureing can to equally circulation and heat exchanger surface.
Therefore, a kind of suitable in oil leak circulation, the stripping abluent with excellent stripping, cleaning and dispersive property is urgently developed.
Summary of the invention
It is an object of the invention to overcome water resource waste when solving the leakage of circulation oil product in prior art big and the halfway weakness of cleaning performance, and the method owing to solving the leakage of circulation oil product in prior art mostly is low cycles of concentration and runs, one is waste substantial amounts of fresh water, two is oily substance and the biological clay of heat exchanger surface residual, the defects such as the burn into ineffective and microbial growth of heat transfer can be brought, it is provided that a kind of peel off cleansing composition and using method thereof.
The invention provides a kind of stripping cleansing composition, wherein, said composition contains D-limonene, Polyethylene Glycol and nonionic surfactant, and the weight ratio of described D-limonene, described Polyethylene Glycol and described nonionic surfactant is 1:0.25-3:0.1-1.5, described nonionic surfactant is Polysorbate type nonionic surfactant.
Present invention also offers a kind of using method peeling off cleansing composition, this using method is: described stripping cleansing composition adds in circulation blowdown after circulation 12-48 hour, and mends with fresh water until the difference of turbidity value before the turbidity value of this circulation and the described stripping cleansing composition of addition is between �� 10%.
According to stripping cleansing composition provided by the invention and using method thereof, on the one hand, though the inventors discovered that D-limonene is water insoluble, but can dissolve each other with arbitrary proportion with water after adding nonionic surfactant, thus can be applied in aqueous phase, the greasy filth of clean cycle water system heat exchanger surface, can be applicable to and there is the circulation that oil product is revealed, and solves heat exchanger surface oil product and adheres to and the corrosion that brings and the problem such as ineffective of conducting heat; On the other hand, the present invention is by together with composite with Polyethylene Glycol to D-limonene, Polysorbate type nonionic surfactant, can be loosened the foundry loam of heat exchanger surface, and makes it be taken away by current, solves the problems such as corrosion and scaling and microbial growth that biological clay brings to circulation.
