Description
Technical field
The present invention relates to a kind for the treatment of process of recirculated water, relate in particular to a kind of leakage of oil circulating water treatment method.
Background technology
Oil leak often can occur in circulating water system, and 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 hydrocarbon mixture of the about 50-350 of boiling spread ℃.In petroleum refining industry, it can refer to light ends oil, also can refer to clean or white.The former comprises cut and the topses such as gasoline (or petroleum naphtha), pyrolysis gasoline, kerosene (or rocket engine fuel), solar oil (or atmospheric gas oil), raffinates oil etc., and they are mainly from devices such as crude distillation, catalytic cracking, thermally splitting, petroleum coking, hydrocracking and catalytic reforming; The latter is the oil product that light ends oil obtains after treating process.Wax oil refers to the heavy component oil of the content of wax, is the intermediate product of oil refining process, is liquid under normal temperature, and not soluble in water, viscosity is larger.Oil leak is the common one of distillation system's material from leakage.
Oil product can produce following harm while leakage: 1) make microorganism grow in a large number, and water quality severe exacerbation, its characteristic slowly discharging makes system water blame to recover; 2) oil product that enters water cooling tower is easily attached on filler, reduces radiating effect and also makes the heavy burden of filler support increase, and when serious, can cause collapsing of filler; 3) oil product is attached on pipeline, can make corrosion-mitigation scale-inhibition medicament not play a role, and causes serious underdeposit corrosion; 4) oil product and the biological clay grown in a large number can adhere in a large number in heat exchange manifold, have a strong impact on heat transfer effect, even can blocking pipe time of a serious nature.
The circulating water treatment of revealing for oil product, large chemical complex takes the treatment process of large excretion and large complement conventionally, first adds adhesive mud remover, peels off rear a large amount of draining, then adds corrosion inhibiting and descaling agent.The method has consumed a large amount of fresh waters and has produced the sewer of equivalent, has wasted water treatment agent, and after blowdown, needs again to improve cycles of concentration, and treatment effect is unsatisfactory.
Chinese patent application CN1193609A discloses the cleaning prefilming agent that waits dirt in a kind of circulating water system for cleaning system microorganism dirt, clean prefilming agent and be made up of biological enzyme scavenging agent, biostats, inorganic salt complex agent and the conventional water quality stabilizer that is made up of inhibiter and dispersion agent, 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 recirculated water by the certain concentration of always possessing the water yield respectively, and maintain this concentration 15-60 days.Chinese patent application CN1125697A discloses the using method of a kind of biological cleanser in circulating water system, and biological enzyme scavenging agent is added in circulating water system, and biological enzyme scavenging agent is fat hydrolase.In circulating water system, can add conventional water quality stabilizer.Adopt the method the greasy dirt in recirculated water can be removed, make leaked substance degraded.Its shortcoming is and has used expensive biological enzyme scavenging agent.
