1: pretreatment

Pump the estimated crude oil into the tank and stir it uniformly. Then we take the sample to check the acid value

2: neutralization

We should put the estimated lye into the crude oil while we must stir it quickly.. The time for putting the lye is 5-10Minutes, we keep on stirring it for 30minutes after the lye is in the crude oil.

3: static settlement  

4: washing

After the static settlement. We let the soap leavings go from the tank bottom . then we adjust the oil temperature to 70-75°C. In order to remove the residual lye and soap. The hot water is 10-15% of the oil.

5:drying: We must dry the oil because it has 0.5% more or less water in the oil.

6: filter

We filter the oil after the temperature is lower 70°C by Dewatering and cooling

 

crude oil refinery main parts: 

de-mixed, degumming , dehydration, deacidification, decolorization, de-waxing, deodorization and crystallization.

 

Advantages of crude oil refinery plant:

(1) High oil yield , obvious economic benefit .

(2) low  Residual oil rate in the dry meal .

(3) Improving the quality of the meal .

(4) Low processing cost , high labor productivity.

 

crude oil refinery detail information:

1. The neutralizing tank is used for acid for acid,alkali refining or rinse

2. The decoloring tank is for bleaching grease

3. The deodorizing tank is sued for deodotization tank

4. The conducting oil furnance provide the heating for production

5. The vacuum pump provide vacumm for bleaching , deodorization which is can reach 755mmkg 

6. The air compressor can dry the bleached clay

7. The air press is for filter clay

8. The stream generator can generate stream distillation 

9. The quality of die refined oil reached to the standards for edible oil and santitation by neutralization using phosphoric acid, water washing, bleaching and stean refining.
