oil refinery Flow chart Rude oil-Neutralize-Decolorize-Deodorize-Cool-Edible oil Explanation: Neutralizer It’s used for ridding off acid ,degumming . Decolorizer It’s used for ridding off/reducing the color of the oil .Deodorizer It’s used for ridding off odor of the oil .Transfer oil furence It’s used supplying for the heats required to the line ,it could make the temperature up to 280 degrees.Air pressurer Blow to dry the Clay for decoloring .Oil filter Clear the oil decolorized .Steam producer Producing steams of high temperater for deodorizer . Operation of the line NeutralizingThere is 2 methods according to adding different quantity alikali and different oil temperature . One is weak alkali(10-16 Be) and high oil temperature (75 degrees),who is only used for weak colour and low acidity; the other is low temperature(20 degrees orso ) and density alkali(20 Be orso),whose is used more . Low temperature(20 degrees orso ) and density alkali(20 Be orso)Adjust the tempetature of oil to 20-30degrees,then put alkali water of 20-30 Be into oil within 5-10 mins, mixing and rise temperate for 20- 60 mins .When the temperature of oil rise to 60 degrees orso , to stop adding heats and immobility for 6-8 hrs to out of the soap particle . Weak alkali(10-16 Be) and high oil temperature (75 degrees) (Omission)Washing by waterAfter be out of the soap paticle from the under of refiner, then continustly adding the heats to 90degrees,then add some hot water to washing the oil , note the temperature of water is higher for 5-10degrees than oil temperature. Then mixing them for 5 mins, then immobility for 4 hrs, put off the soap water ,so for 2-3 times which is confirmed as the oil quality . Oil washed is added heat to 105 degrees orso , to mix then dehydrate for 1 hour ,also directly is pumped into decolorizer vessel for dry for 30 mins in the vacuum condition . Decolorizer Pump the oil netralized into decolorizer vessel , samely mixing to rise its temperature to 90 degrees,then mixing for 30 mins,to reduce water to 0.1% ,then put a little clay (decoloring media) 2-4 % of total oil ,mixing for 30 mins ,to reduce the temperature to 70 degrees, then filte the clay with oil filter,to get the oil decolorized . Deodorizer Pump the oil decolorized into deodorizer vessel in 755mmHg of vacuum,240 degrees –260degrees , to distillate for 4hrs wit steams . Then turn off the steams to open the cooler to reduce the temperature to 40-80 degrees, then check a little oil , if ok to pack it . For more detail machine technology,please contact
