Information

Technical requirements of the continuous degumming and deacidification section:

1. After the filtering, the impurity content of the crude oil should be no more than 0.2%

2. After the pre-heating, add the phosphoric acid into the crude oil and the temperature is 60 ℃

3. The concentration of addition phosphoric acid is 85%. The addition amount of phosphoric acid is equal to 0.03%-0.15% of the oil weight.

4. The acid reaction time is 15-40min.

5. When doing alkali refining, the concentration of addition alkali liquor is 10%-20%( baume degree) or according to small sample test to ensure.

6. Theoretically, the addition amount of alkali: 7.14×10-4 × oil weight× acid price. For the acidification section, alkali amount of phosphoric acid is calculated according to increase amount of acid value. That is, 1.6× the addition amount of phosphoric acid, super alkali amount is equal to 10%-15%of theoretic alkali amount.

7. The reaction temperature of alkali is 80-45℃, the reaction time is 10-50min, and the stir speed is about 15-40rpm.

8. The temperature of oil-soap mixture in soap centrifuge is 85-90℃,the pressure of light export oil is 0.10-0.30MPa.

9. When doing washing, the temperature of addition soft water is 90-95℃, the addition amount is equal to 10%-15% of oil weight.

10. The temperature of oil-water mixture into dewatering centrifuge is 85~90℃,the pressure of light export oil is 0.10-0.30MPa.

11. The oil temperature is 105~130℃ which will into the desolvation or dryer tower,and its vacuum degree is -0.09MPa.

12. After the desiccation process, the water content in oil is 0.05-0.1%, must not exceed 0.2%, or it will have adverse effect on the back-end processing of refining process.
