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.
