Description
Technical field
The present invention relates to a kind of treatment process of recirculated water, relate in particular to a kind of leakage of oil circulating water treatment method.
Background technology
In circulating water system, through regular meeting oil leak takes place, the oil product that is leaked to circulating water system generally comprises lightweight oil and wax oil.Lightweight oil is generally made a general reference the about 50-350 of boiling spread ℃ hydrocarbon mixture.In petroleum refining industry, it can refer to light ends oil, also can refer to clean or white.The former comprises gasoline (or petroleum naphtha), pyrolysis gasoline, kerosene (or rocket(engine)fuel), solar oil cuts such as (or atmospheric gas oils) and tops, raffinates oil etc., and they are mainly from devices such as crude distillation, catalytic cracking, thermally splitting, petroleum coking, hydrogen cracking and CRs; The latter is the oil product of light ends oil through obtaining after the treating process.Wax oil is meant the heavy component oil of the content of wax, is the intermediate product of oil refining process, and for liquid, not soluble in water, viscosity is bigger down for normal temperature.Oil leak is the common a kind of of distillation system's material from leakage.
Oil product can produce following harm when revealing: mikrobe is grown in a large number, and the water quality severe exacerbation, its characteristic that slowly discharges is blamed to recover system water; 2) oil product of entering water cooling tower is attached on the filler easily, reduces radiating effect the heavy burden of filler support is increased, and can cause collapsing of filler when serious; 3) oil product is attached on the pipeline, and the corrosion-mitigation scale-inhibition medicament can not be played a role, and causes serious underdeposit corrosion; 4) oil product and the biological clay grown in a large number can adhere in heat exchange manifold in a large number, have a strong impact on the heat exchange effect, when of a serious nature even can blocking pipe.
For the circulating water treatment that oil product is revealed, large chemical complex takes the big treatment process of mending of big row usually, promptly adds adhesive mud remover earlier, peels off a large amount of drainings in back, adds corrosion inhibiting and descaling agent again.This method has consumed a large amount of fresh waters and has produced the sewer of equivalent, has wasted water treatment agent, and need improve cycles of concentration again after the blowdown, and treatment effect is unsatisfactory.
One Chinese patent application CN1193609A discloses the cleaning prefilming agent that is used for dirts such as cleaning system mikrobe dirt in a kind of circulating water system; Clean prefilming agent and constitute by biological enzyme scavenging agent, biostats, inorganic salt complex agent with by the conventional water quality stabilizer that inhibiter and dispersion agent are formed, wherein inorganic salt complex agent is made up of silicate, manganate, carbonate, orthophosphoric acid salt.Purging method is under the normal operating condition of circulating water regiment commander thermal load; Biological enzyme scavenging agent, biostats, inorganic salt complex agent and conventional water quality stabilizer are joined in the recirculated water by the certain concentration of always possessing the water yield respectively, and kept this concentration 15-60 days.One Chinese patent application CN1125697A discloses the method for use of a kind of biological cleanser in circulating water system, and biological enzyme scavenging agent is added in the circulating water system, and biological enzyme scavenging agent is a fat hydrolase.Can add conventional water quality stabilizer in the circulating water system.Adopt this method can the greasy dirt in the recirculated water be removed, make the leaked substance degraded.Its shortcoming is has used expensive biological enzyme scavenging agent.
