Description
Technical field
The present invention relates to a kind of recirculated water greasy filth 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, a kind of to be suitable for oil leak circulation, the greasy filth with excellent stripping, cleaning and dispersion performance is clear
Lotion is urgently developed.
The content of the invention
It is an object of the invention to overcome to solve water resource waste in circulation oil product leakage method in the prior art
Greatly, adding of agent concentration is big and cleans halfway weakness, and due to solving the leakage of circulation oil product in the prior art
Method be mostly the operation of low cycles of concentration, first, waste substantial amounts of fresh water, second, oily substance can be remained in circulation,
A kind of the defects of corrosion and unfavorable heat transfer for being brought to circulation and heat exchanger surface, there is provided greasy filth cleaning agent combination
Thing and its application method.
The present invention provides a kind of greasy filth cleansing composition, wherein, said composition contains D- limonenes and polyethylene glycol,
And the weight ratio of the D- limonenes and the polyethylene glycol is 1：0.25-1.5.
Present invention also offers a kind of application method of greasy filth cleansing composition, which is：
（1）Will the greasy filth cleansing composition add circulation in circulate 6-24 it is small when after add aquae hydrogenii dioxidi
Solution, and not blowdown；
（2）By the circulation circulation 12-48 it is small when after blowdown, and mend with fresh water until the circulation oil
The difference of oil content value before content value and the addition greasy filth cleansing composition is between ± 10%.
The greasy filth cleansing composition and its application method provided according to the present invention, it is of the invention by D- limonenes and poly- second two
Alcohol compounds together, it is mutually played cooperative effect, cleans the heat exchanger of water circulating system tube wall influenced by oil leak, clearly
It is good to wash effect, cost is low, and dosage is few, adds aqueous hydrogen peroxide solution, hydrogen peroxide and the ferrous iron in water after the washing
Ion, can form Fenton reagent, the oily substance that accelerated degradation washes down, avoids secondary pollution.By the greasy filth cleaning agent and
Application method according to the invention is applied to that, there are in the recirculating cooling water system of oil product leakage, circulation can be not being reduced
On the basis of cycles of concentration, reduce oil product and be leaked to corrosion and the scale problems that circulation is brought, there is higher economy
Benefit and social benefit.
Other features and advantages of the present invention will be described in detail in subsequent specific embodiment part.
