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 turned into 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, maximally effective water-saving method to improve cycles of concentration.But if recirculated water
System leak material not only wastes substantial amounts of fresh water, and 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 suspension and material in the bacterium and recirculated water of growth form biological clay, are deposited on
In heat transmission equipment, heat transfer effect is influenceed, causes corrosion；Second, leakage material cause bactericide to fail, material directly and chlorine
Reacted with non oxidizing bactericide, the effect of bactericide is influenceed, 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 the inhibition of system and scale inhibition effect.
At present, the method for solving the leakage of circulation oil product is mostly low cycles of concentration operation, large excretion and large complement, is added simultaneously
Peeling off cleaning agent reduces the various adverse effects that oil leak is brought to circulation and heat exchanger surface.Low cycles of concentration
Operation can waste a large amount of fresh waters, the oily substance remained 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 applied to oil leak circulation, have excellent stripping, cleaning and the stripping of dispersive property clear
Lotion is urgently developed.
The content of the invention
When solving the leakage of circulation oil product it is an object of the invention to overcome in the prior art water resource waste it is big and
The halfway weakness of cleaning performance, and the method revealed due to solving circulation oil product in the prior art is mostly low concentration
Multiple is run, first, substantial amounts of fresh water is wasted, second, the oily substance and biological clay of heat exchanger surface residual, 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 invention provides one kind peel off cleansing composition, wherein, said composition contain D- limonenes, polyethylene glycol and
Anion surfactant, and the weight ratio of the D- limonenes, the polyethylene glycol and the anion surfactant is
1：0.25-3：0.1-1.5, the anion surfactant are aliphatic alcohol polyoxyvinethene phosphate salt anionic surfactant activity
Agent.
Present invention also offers a kind of application method for peeling off cleansing composition, the application method is：By the stripping
Cleansing composition adds blowdown after circulation 12-48 hours in circulation, and mends with fresh water until the circulation
Turbidity value and add it is described peel off cleansing composition before turbidity value difference between ± 10%.
According to stripping cleansing composition provided by the invention and its application method, on the one hand, the inventors discovered that D- lemons
Though lemon alkene is not soluble in water, can be dissolved each other after anion surfactant is added with water with arbitrary proportion, it is possible thereby to apply
In aqueous phase, the greasy filth of clean cycle water system heat exchanger surface, the circulation that oil product leakage be present, solution are especially applicable in
The problems such as corrosion and unfavorable heat transfer that certainly heat exchanger surface oil product is adhered to and brought；On the other hand, it is of the invention by D- limonenes, fat
, can be with loose heat exchanger surface together with fat alcohol polyoxyethylene ether phosphate salt anion surfactant compounds with polyethylene glycol
Foundry loam, and it is taken away by current, solve corrosion and scaling and microbial growth that biological clay is brought to circulation
The problems such as.
Other features and advantages of the present invention will be described in detail in subsequent specific embodiment part.
