Description
Technical field
This utility model relates to sump oil process field.
Background technology
The processes such as water, overhaul of the equipments and chemical examination blowdown are cut in electro-desalting during crude refining, Oil Tank can produce substantial amounts of oil-polluted water.The sump oil that oil-containing sewage treatment system regulating reservoir (tank) and oil interceptor operating unit reclaim mainly is made up of petroleum-type, silt, various chemical medicaments and water, general presented in W/O or O/W/O type emulsion at normal temperatures, is difficult to breakdown of emulsion.Sump oil is typically proceeded to storage tank by oil plant, under the effect of demulsifier, utilizes heating (generally 60～70 DEG C) static sedimentation separation and recovery petroleum-type freshening.Its shortcoming is that time of repose is long, and thermal energy consumption is big, and in recovered oil, impurity content is high, and the steady production of distillation system is easily impacted by freshening, even results in systemic breakdown time serious, it has to carry out unconventional maintenance.
Method document about sump oil purification is reported more.200810103977.0 1 kinds of sump oils of the patent No. and acid oil focus on technique and processing system thereof, and this utility model processes technique and includes that (1) filters;(2) enter reactor, stablize at 6.0-8.0 to sump oil pH value at the pneumatically supported sodium carbonate liquor that is simultaneously introduced, be subsequently adding demulsifier and flocculant continues reaction;(3) stop air supporting, staticly settle;(4) the purification oil on reactor upper strata is obtained GB crude oil by normal, decompression dehydration;Sewage discharges after vertical natural oil removing pot and oil and water filters filter;Mud uses cement-based solidified, and quick lime and aluminium oxide help solidifying formation solidification sludge.Sump oil of the present utility model and acid oil focus on technique and not only considerably reduce the pollution to oil field surrounding and the corrosion to equipment, and turn waste into wealth, and have reclaimed substantial oil, have improve the economic benefit in oil field, and solidification sludge can be directly used for building.Above-mentioned sump oil purification method be essentially all in sump oil sample addition medicament (playing dehydrating and removing impurities effect), the most at a certain temperature, or natural subsidence be centrifuged or ultrasonic assistant breakdown of emulsion.It is said that in general, the basic composition of oil plant waste oil recovery is: petroleum-type [hydro carbons, non-hydrocarbons (resin and asphalt)], solid impurity (silt particle, salt) and moisture content, be a kind of the most stable, be more difficult to the Water-In-Oil emulsification system of breakdown of emulsion than crude oil.Therefore, use the treatment effect being similar to crude oil demulsification dehydration remove impurity unsatisfactory, show that (1) moisture and impurity content are high；(2) hydro carbons and non-hydrocarbons (resin and asphalt freshening) can not be separated.If freshening, affecting distillation system and normally produce, can make distillation system's stop production to overhaul time serious, loss is serious.
