Oil neutralizing machine Main Processes Introduction

(Hydration De-gumming & Alkali Refining De-acidification Process:)

1) Neutralization: The crude oil is output by the oil feed pump from the oil tank, and next enters the crude oil heat exchanger to recover part of heat after metering and then is heated to the required temperature by the heater. After that, the oil is mixed with the metered phosphoric acid from phosphate tank, and then enters the conditioning tank to make the non-hydratable phospholipids in oil change into the hydratable phospholipids. Add the alkali for neutralization, and the alkali quantity and alkali solution concentration depend on the quality of the crude oil. Through the heater, the neutralized oil is heated to the temperature (80~90℃) suitable for centrifugal separation to remove the phospholipids, FFA and other impurities in the crude oil. Then the oil goes to the washing process.

2) Washing: There are still about 500ppm soap in the neutralized oil from the separator. To remove the remaining soap, add into the oil about 5~8% hot water, with water temperature 3~5 ℃ higher than the oil generally. To achieve more stable washing effect, add phosphoric acid when washing. The re-mixed oil and water in the mixer is heated to 90-95℃ by the heater, and then enters the wash separator to separate the remaining soap and most water. The water with soap and oil enters into oil separator to separate out oil in the water. Further catch the oil outside, and the waste water is discharged to the sewage treatment station.

3) Vacuum drying stage: There is still moisture in the oil from the wash separator, and the moisture will affect the stability of the oil. So the oil at about 90℃ should be sent to vacuum drier to remove the moisture, and then the dehydrated oil goes to the de-coloring process. Finally, pump out the dry oil by canned pump.
