Description
Technical field
The present invention relates to a kind of disposal of oily sludge medicament and preparation thereof, using method, especially to the treatment agent of the oily sludge that the tank bed mud produced in crude oil storage and transport process and refinery produce, belong to oilfield chemical technical field.
Background technology
Oily sludge is oil-field development, and one of principal pollutant of producing in oil storage and transportation and the refining course of processing, its main component is crude oil, water and silt particle, has the features such as oleaginousness is high, viscosity is large, particle is thin, dehydration is difficult.According to statistics, the oily sludge total amount that current China produces every year reaches more than 500 ten thousand tons, and the crude resources wherein contained is about about 1,000,000 tons, along with most of oil field enters middle and later periods mining phase, extraction Water in oil rate is more and more higher, and continuation also increases by the output of oily sludge.Sludge in Oilfields composition is extremely complicated, general containing heavy metal salts etc. such as a large amount of aged crude oil, wax, bituminous matter, colloid and suspended solid, bacterium, parasite, salt, sour gas, corrosion product and a small amount of mechanical impurity, copper, zinc, chromium, mercury, simultaneously also containing cacodorous toxic substances such as benzene homologues, phenols, anthracene, pyrenes; In addition, oil field also adds the water treatment agents such as a large amount of flocculation agent, inhibiter, Scale inhibitors, sterilant in process of production.If these compositions are not dealt carefully with, direct discharge can cause severe contamination to surrounding soil, water body, vegetation and air etc., worsens ecotope; In addition, in Sludge in Oilfields, also containing a large amount of petroleum substance, metal and inorganic mineral etc., there is very important petroleum vapor recovery and metallic ore material regeneration value, therefore oily sludge is again a kind of resource, if directly discharge the wasting of resources especially.Based on the needs of environment, society and Development of Economy, disposal of oily sludge has become each elephant enterprise problem in the urgent need to address.
From the phase at the beginning of the seventies in last century, researchists a large amount of both at home and abroad just takes up the research work of disposal of oily sludge, through the unremitting effort of decades, successively have developed multiple process for treating oil-containing sludge, but is also difficult to so far form suitability for industrialized production.The key of disposal of oily sludge process is oil removing and dehydration, only has the oil content effectively removing oily sludge surface attachment, the more effective removal moisture of ability, thus reaches the object of resource utilization, minimizing.Oily sludge Chemical treatment method conventional both at home and abroad is at present broadly divided into: the composite oil removing between the oil removing of tensio-active agent wash-out, emulsion splitter breaking milk and removing oil, soda lye wash oil removing, flocculation agent flocculation deoiling, various medicament.Lung biopsy can obtain good treatment effect to oily sludge to a certain extent, but often kind of method has respective relative merits and use range.Such as, although the oil removing of tensio-active agent wash-out shows higher oil removal rate, need higher concentration and treatment temp, this can make You Heshui dissolve each other, and in emulsified state, is not easy to former oil recovery; And biological degradability is poor, there is certain toxicity, seriously have impact on Environment-Ecosystem.In order to ensure the Sustainable development of environment for human survival, it is imperative to develop ecotope free of contamination disposal of oily sludge medicament.
Summary of the invention
For the deficiency of existing treatment agent, the invention provides a kind of disposal of oily sludge medicament and preparation thereof, using method.This oil-sludge treatment medicament demulsification is good, crude oil recovery rate is high, production cost is low, environmental protection and preparation method is simple, applied range.
