The Research And Preparation Of High Efficient Waterbased Crude Oil Cleaning Agent In Metal Surface

In the oil field, oil refining, drilling platform and other industries in the crude oil pipeline,containers, and equipment, storage tanks, machinery, assignments, wash filter material andsome down hole tools, oil sludge, heavy asphalt crude dirt, oil coke and cleaning oil dirt ofmetal surface,which is one of the issues need to be studied in the petrochemical industry.Industrial cleaning industry is facing more and more strict regulations and policies whichmain is to protect our environment for survival. The traditional cleaning agents on theenvironment generated the destruction of the ingredients. The chemical cleaning technologydevelopment has made some progress, and has resolved some production problems in thepractice, but the current chemical technology in general is decay trend.We need to protect thenature environment, chemical cleaning technology trends is bound to develop integrated,refined, environment-friendly and functional.We have developed a high-performance water-based metal cleaning which agent formetal surface. This paper introduces the cleaning agent is comprised of surface active agent,compound corrosion inhibitor and help lotion compounded synergistic effect, which can beused in cleaning surface of wellbore in oil wells homework project, and cleaning oil casingwall in crude oil and dirt, and can remove the bottom of the asphalt and dead oil, also can beused for cleaning the oil dirt of underground working tools, machinery and equipment, andcan to relieve congestion and pollution effect.This paper describes the development of the cleaning agent is the observation of somesurfactants dissolve the crude oil, and determination and surfactant cloud point, first choosebetter, and relatively cloud point is higher, and the known HLB value in the reasonable scope(8and14) between six kinds of surfactant:690#, OP-10, NP-10, KE-1,1227, EL-5.From thescreening of the the six kinds of surfactant mixtures, and do a lot of orthogonal experiment todetermine the quality of water base metal crude oil formula.This paper studies the effect that the efficient cleaning water base metal crude oilwashing agents under static conditions the skim temperature and the skim time for cleaningoil, and the cleaning agent performance is valued. Results show that this cleansing agentshave higher decontamination ability and better wetting role of industrial dirt bettersolubilization, emulsification after cleaning the metal surface no oil film; The cleaning agentto metal have a higher rust resistance,as the metal is clean, for a period of time without antirust processing; Non-corrosive to metal surface, after cleaning the metal surface can keepthe original metal luster; The cleaning agent,there are some technological properties, such asroom temperature can be used, and cleaning effect is very good, the operation is simple, easyto be dehydrated oil off, to the operation of the health of workers also no harm, in "threewastes" treatment is easy, pollution to the environment are also small, in the cost of makingthe price also is cheap, etc. This paper developed water-based oil metal cleaning agent,mainlyfor the metal outer surface of the crude oil to the development of different cleaning agents toclean it.
