Abstract
The invention discloses an environmental protection treatment method for recovery treatment and reutilization of wastewater in an oil refining process. The environmental protection treatment method comprises: 1, classification recovery of wastewater; 2, classification treatment of the wastewater, wherein cooling water, emulsifying water, boiler wastewater, and alkali-acid-containing wastewater are conveyed to corresponding treatment equipment and treatment is performed, the emulsifying water is filtered through a filtration device, the boiler wastewater is treated by a precipitation and filtration device, the alkali-acid-containing wastewater is conveyed into a neutralization chamber and is neutralized, and finally the obtained treated wastewater is introduced into a free state oil-containing wastewater collection pool; and 3, utilization of the wastewater, wherein oil field produced water is mixed in the free state oil-containing wastewater collection pool. According to the present invention, various wastewater production sources are subjected to individual classification recovery, and after the preliminary pretreatment is performed, the pre-treated wastewater is mixed with the oil field produced water according to a certain ratio, such that the water quality achieves the corresponding standard, and the treatment method is environmental protection and energy saving.
Description
Technical field
The present invention relates to a kind of oil refining energy-saving and emission-reduction method, and in particular to the environment-friendly treatment method that waste water recycling device is recycled in a kind of oil refining process, belong to energy-conserving and emission-cutting technology field.
Background technology
Energy-saving and emission-reduction are the important subjects of current oil refining industry, and by correlational study for many years, related oil refining process is optimized, and in environmental protection and energy saving technical elements certain optimization and lifting has been obtained；In recent years, crude oil in China processing total amount increased 49.5%, and refine oil comprehensive energy consumption and have dropped 12.1%, illustrate that oil refining process energy saving optimizing played an important role；Currently, the optimization of oil refining process energy saving optimizing technology and reform mainly from reduce oil refining process always with can, low temperature exhaust heat recycle and waste water management three in terms of；Wherein, existing enterprise always has been carried out deep technological improvement to reducing oil refining process with energy and low temperature exhaust heat recycling, but due in oil refining process, the cost of water is than relatively low, and its management equipment needs to take considerable time that human cost goes research and development, therefore, existing enterprise is deep not enough for waste water management research.
The content of the invention
（One）The technical problem to be solved
To solve the above problems, the present invention proposes the environment-friendly treatment method that waste water recycling device is recycled in a kind of oil refining process, its method is simple, take after preliminary pretreatment when main, being mixed into oil field extracted water according to corresponding ratio carries out mixed processing, so that water quality reaches corresponding standard, realize that the environmental protection and energy saving to oil refining process optimize after reaching using standard.
（Two）Technical scheme
The environment-friendly treatment method that waste water recycling device is recycled in the oil refining process of the present invention, methods described comprises the steps：
The first step, classification of waste is reclaimed, and according to the difference of the waste water quality for producing, by different reclaimers free state oily waste water, cooling water, emulsified water, boiler wastewater, the waste water containing alkali, acid is reclaimed；And deliver in respective handling pond；
Second step, classification of waste process, above-mentioned cooling water, emulsified water, boiler wastewater, the waste water containing alkali, acid are delivered to alignment processing equipment and are processed, and wherein emulsified water is filtered by defecator, boiler wastewater is processed by precipitation and defecator, and the waste water containing acid, alkali sends into neutralization chamber neutralization；During it finally to be imported to free state oily waste water collecting pit；
3rd step, water reuse；Free state oily waste water collecting pit is mixed into into oil field extracted water.
Further, the waste water in the free state oily waste water collecting pit：Oil field extracted water is 1:5.
（Three）Beneficial effect
Compared with prior art, the environment-friendly treatment method that waste water recycling device is recycled in the oil refining process of the present invention, each classification is carried out using each waste water generating source to reclaim, and do after preliminary pretreatment, deliver at free state oily waste water, and be sufficiently mixed with free state oily waste water, being mixed into oil field extracted water then according to ratio carries out mixed processing, so that water quality reaches corresponding standard, its processing method environmental protection and energy saving.
Specific embodiment
A kind of environment-friendly treatment method that waste water recycling device is recycled in oil refining process, methods described comprises the steps：
The first step, classification of waste is reclaimed, and according to the difference of the waste water quality for producing, by different reclaimers free state oily waste water, cooling water, emulsified water, boiler wastewater, the waste water containing alkali, acid is reclaimed；And deliver in respective handling pond；
Second step, classification of waste process, above-mentioned cooling water, emulsified water, boiler wastewater, the waste water containing alkali, acid are delivered to alignment processing equipment and are processed, and wherein emulsified water is filtered by defecator, boiler wastewater is processed by precipitation and defecator, and the waste water containing acid, alkali sends into neutralization chamber neutralization；During it finally to be imported to free state oily waste water collecting pit；
3rd step, water reuse；Free state oily waste water collecting pit is mixed into into oil field extracted water.
Wherein, the waste water in the free state oily waste water collecting pit：Oil field extracted water is 1:5.
Found by studying, the main generation link of waste water comes from the straight run distillation production link of crude oil, and the refining process of the distillation in heavy oil, cracking and some fractions can also produce waste water；When environmentally friendly optimization processing is carried out to waste water, mainly carry out each classification using each waste water generating source to reclaim, and do after preliminary pretreatment, deliver at free state oily waste water, and be sufficiently mixed with free state oily waste water, being mixed into oil field extracted water then according to ratio carries out mixed processing so that water quality reaches corresponding standard, realizes that the environmental protection and energy saving to oil refining process optimize after reaching using standard.
Embodiment described above is only that the preferred embodiment of the present invention is described, and not the spirit and scope of the present invention are defined.On the premise of without departing from design concept of the present invention; various modifications and improvement that this area ordinary person makes to technical scheme; protection scope of the present invention all should be dropped into, the technology contents that the present invention is claimed all have been recorded in detail in the claims.
