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
In circulating water system, often oil leak can occur, the oil product being leaked to circulating water system generally comprises lightweight oil and wax oil.The hydrocarbon mixture that boiling spread is about 50-350 DEG C generally made a general reference by lightweight oil.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, 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, and be liquid under normal temperature, 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 when revealing: 1) make microorganism grow in a large number, water quality severe exacerbation, the characteristic of its slow releasing makes system water blame to recover; 2) oil product entering water cooling tower is easily attached on filler, reduces radiating effect and the heavy burden of filler support is increased, can cause collapsing of filler time serious; 3) oil product is attached on pipeline, corrosion-mitigation scale-inhibition medicament can be made not play a role, cause 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.
For the circulating water treatment that oil product is revealed, large chemical complex takes the treatment process of large excretion and large complement usually, namely first adds adhesive mud remover, a large amount of draining after peeling off, then adds corrosion inhibiting and descaling agent.The method consumes a large amount of fresh waters and produces the sewer of equivalent, wastes water treatment agent, and needs after blowdown again to improve cycles of concentration, and treatment effect is unsatisfactory.
Chinese patent application CN1193609A discloses in a kind of circulating water system and waits the cleaning prefilming agent of dirt for microorganism dirt in cleaning system, cleaning prefilming agent is 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, and 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 maintains this concentration 15-60 days.Chinese patent application CN1125697A discloses the using method of a kind of biological cleanser in circulating water system, adds in circulating water system by biological enzyme scavenging agent, and biological enzyme scavenging agent is fat hydrolase.Conventional water quality stabilizer can be added in circulating water system.The method is adopted by the oily waste degradation in recirculated water, leaked substance to be degraded.Its shortcoming is and employs expensive biological enzyme scavenging agent.
