Description
Technical field
The present invention relates to a kind of recirculated water stripping cleansing composition and its application method.
Background technology
Water resource has become an important factor for restricting petroleum chemical enterprise's development, and water conservation is very urgent.Circulation is
One with water rich and influential family, at present, it is that recirculated water is most direct, most effective water-saving method to improve cycles of concentration.But if recirculated water
System leak material not only wastes substantial amounts of fresh water, but also the dosage of water treatment agent, it is necessary to the displacement of substantial amounts of fresh water
Also roll up, cost increases substantially.
Oil leak is a kind of situation that petroleum chemical enterprise's circulation often occurs.Performance of the oil leak in recirculated water
For：When the oil content increase of system, second, bacterial number is significantly exceeded.Its endanger have it is following some：First, it is bacterial growth
Nutrition is provided, makes bacterium raised growth, the suspended matter and material in the bacterium and recirculated water of growth form biological clay, are deposited on
In heat transmission equipment, heat transfer effect is influenced, causes corrosion；Second, leakage material cause fungicide to fail, material directly and chlorine
Reacted with non oxidizing bactericide, the effect of fungicide is influenced, so that bacterium raised growth；Third, some materials, such as heavy oil
Leakage, is adhered on tube wall, cooling tower or heat transmission equipment, influences to conduct heat and cool down；Fourth, bacterium raised growth, to inhibition, resistance
Dirty agent has degradation, so as to influence inhibition and the scale inhibition effect of system.
At present, the method for solving the leakage of circulation oil product is mostly low cycles of concentration operation, and large excretion and large complement, add at the same time
Peeling off cleaning agent reduces the various adverse effects that oil leak is brought to circulation and heat exchanger surface.Low cycles of concentration
A large amount of fresh waters can be wasted by running, and remaining oily substance in circulation, equally can give circulation and heat exchanger
Adverse effect is brought on surface, and circulation treatment effect cannot ensure.
Therefore, it is a kind of to be suitable for oil leak circulation, it is clear with excellent stripping, cleaning and the stripping of dispersion performance
Lotion is urgently developed.
The content of the invention
Solved in the prior art it is an object of the invention to overcome water resource waste during the leakage of circulation oil product it is big and
The halfway weakness of cleaning performance, and since the method for solving the leakage of circulation oil product in the prior art is mostly low concentration
Multiple is run, first, substantial amounts of fresh water is wasted, second, the remaining oily substance of heat exchanger surface and biological clay, can bring corruption
Lose, ineffective and microbial growth of conducting heat the defects of, there is provided one kind peels off cleansing composition and its application method.
The present invention provides one kind peel off cleansing composition, wherein, said composition contain D- limonenes, polyethylene glycol and
Nonionic/anionic surfactant mixture, and the D- limonenes, the polyethylene glycol and the nonionic/anion
The weight ratio of surfactant mixture is 1：0.25~3：0.1~1.5, the nonionic surfactant is polysorbate type
Nonionic surfactant, the anion surfactant are long-chain alkyl aryl sulfonate anionic surfactant.
Present invention also offers a kind of application method for peeling off cleansing composition, which is：By the stripping
Blowdown after cleansing composition is added when circulation 12~48 is small in circulation, and mend with fresh water until the circulation
Turbidity value and add it is described peel off cleansing composition before turbidity value difference between ± 10%.
The stripping cleansing composition and its application method provided according to the present invention, on the one hand, the inventors discovered that D- lemons
Though lemon alkene is not soluble in water, can be dissolved each other after nonionic/anionic surfactant mixture is added with water with arbitrary proportion, by
This can be applied in water phase, the greasy filth of clean cycle water system heat exchanger surface, can be applicable to there are oil product leakage circulation
The problems such as water system, the corrosion and ineffective heat transfer that solve the adhesion of heat exchanger surface oil product and bring；On the other hand, it is of the invention by D-
, can be with loose heat exchanger surface together with limonene, nonionic/anionic surfactant mixture and polyethylene glycol compound
Foundry loam, and make it be taken away by current, solves corrosion and scaling and microbial growth that biological clay brings to circulation etc.
Problem.
Other features and advantages of the present invention will be described in detail in subsequent specific embodiment part.
