oil-water separation hydrocyclones ** the eighties the development of a centrifugal oil-water separator.its basic principle of the conventional solid-liquid separation hydrocyclone similar to those that use centrifugal force generated by the bound vortex,forcing the oil-water separation in the centrifugal force field,the density of water near the downstream wall continued to rotate,from the lower reaches of export from,and the oil phase to the center of low pressure are part of,and reverse north korea cyclone outlet upstream movement of the liquid flow in the hydrocyclone with a very short duration,generally about a few seconds,rotating hydraulic oil-water separator current in multiples of a higher centrifugal force.the fluid in the hydrocyclone can be accelerated to 3000rpm,the centrifugal force of a multiple of 2000g,it ** mainly used in oil field produced water crude oil dehydration and low sewage treatment.oil-water separation hydrocyclones to simple structure,**all size,light weight,no moving parts and filter elements,low operating costs,s**ing energy,separation efficiency,short processing time ** being field advantage attention.
oil-water separation hydrocyclones development
liquid-liquid separation of the field of research and development work in england in 1967 from the coast of hainan"torreycanyon"tanker died after the incident began.at that time,a large number of crude oil leaked,resulting in a large area of sea pollution and the death of a large number of organi**s.in th** case the university of southampton professor martin thew and h** colleagues began a liquid-liquid hydrocyclone technology.after several years of efforts,the first liquid-liquid swirl oil remover in 1984 in the experimental success of the marine platform.commercial sales began in 1985.cspi company in 1989 from bwn vortoil pty ltd swirl vortoil purchased technology,and ** committed to improving the design of the cyclone,and finally in liquid-liquid hydrocyclone of the applications to gain a leading position.
at present,the hydrocyclone ** at home and abroad the most prom**ing solution-one liquid separation equipment,and its research and development work largely concentrated in three areas:
first,the importation of non-shear pump of choice and the special non-shear pump.
second,the system configuration.
third,the ability to better separation of **all droplets of the new cyclone development.
through research to make oil hydrocyclone used in offshore oil platform,will be liquid-liquid hydrocyclone used in medicine,food,chemical,petrochemical and mining industries.the solid-liquid hydrocyclone used in low-pulp,pharmaceutical,food and chemical industry.
in foreign countries,oil-water hydrocyclone separation after than ten years of technology development and product research,has become a new generation of centrifugal oil-water separator,were successfully used in oil field produced water treatment.th** separator ** simple in structure,**all size and performance advantages of multi-purpose,production and application in the field of great potential.in the course of oil field development,the development of almost all water-bearing period of experience,in particular,accompanied by strong water-drive technology of large-scale applications,see the water as early as crude oil,growing faster than the mo**ture content.stable development period,the mo**ture content of crude oil up to 60~70%,the development of the latter,the mo**ture content of crude oil as high as 90%.
however,water content of crude oil h**e done great harm.for example,to deal with increased fluid,reducing pipes,the effective utilization of equipment;increase the tran****sion power consumption process;caused by piping and equipment fouling and corrosion;the impact of oil refining operations,such as normal.for th** reason,the development of all countries in the world crude oil strict mo**ture control.such as china's"oil and gas gathering and transportation design code"provides that:passing the water content of crude oil should be not than 1%;quality of the water content of crude oil should be not than 0.5%;foreign requirements ranging from 0.03 to 2.0 percent.on the other hand,crude oil removal from oily wastewater,how to handle and use,but also aroused people's attention.sewage treatment ** important the whole world,the oil field wastewater treatment recharge or d**charge has become a must.ground works in the oil fields,the oil-water separation equipment ** one of the ind**pensable equipment.
the rapid development of oil and water separation equipment for several decades,from the original write-oil pool,the natural separation of the beginning of the settlement,the development of a wide range of oil-water separator.electrical devices such as dehydration,free water separator,filler-type of free water separator,air flotation and filtration and so on.the beginning of the 80's to oil-water separation hydrocyclones represented by centrifugal oil-water separation system in crude oil dehydration and treatment of wastewater applied.
however,only in our country from the 90's began to h**e a better understanding of the technology of individual oil fields h**e begun to introduce products and put into use.at present,on the application of hydrocyclones ** also limited to the design of the majority of two-phase solid-liquid separation,separation in terms of technological development,or economic interests,as soon as possible in the development of a hydrocyclone liquid-liquid separation equipment like to enhance the removal of sewage hydrocyclone technology ** necessary to understand and study.
