Abstract:
    The invention relates to grease degumming technology. It includes the following steps: cooling the crude oil to 60-70 degree centigrade; adding 0.05%-0.2% of the oil weight phosphoric acid or citric acid; stirring by flash mixing reactor to make the oil and acid touch fully; cooling to 40-45 degree centigrade by cooler; entering acid reaction pot to stir at 60-70r/min for 60-90min to make the conversion of the non hydrated phosphatide reach over 98%; adding 1%-2% soft water with 1:1 phosphatide content; adding 1%-3% flocculant and neutralization reaction alkali with 2%-3% density; using flash mixing reactor to make the oil, water, alkali touch fully; heating to 85-90 degree centigrade to dissolve colloid phosphatide, make hydrated phosphatide absorb water fully; entering hydrating reaction neutralizing pot to stir at 60-70r/min for 20-30min; using the water absorption of the phosphatide to make the flocculation particle form glue ball; entering centrifuge to separate; heating to 100-110 degree centigrade; dehydrating by vacuum dryer with less than 60mbar; cooling to 40-50 degree centigrade by heat exchanger to store in tank farm. The product oil has less than 30ppm phosphorus content of the oil, lighter color, can satisfy the standard for broil oil, has less than 30ppm oil remnant dissolve which satisfy the standard of country sanitation, can be directly put into market.
