sunflower,rapeseed,cotton,soybean edible oil refinery/crude oil refinery plant

crude oil refinery plant

1. Introduction

(1) The method of oil refineries Process can be divided into intermittence oil refining, semi-continuous oil refining and continuous oil refining.

(2) The main parts of oil refining plant:: neutralization, decoloration, deodorization, derosination, degumming and dewaxing. ( most of these parts are physical process)

2. Main Refining Process.

(1) Crude oil alkali refining

First, crude oil is put into neutralization tank. When the oil heated to 70-80 °C, the alkali water which heated by hot water is put into the balance tank. Then they are beginning to reaction to rid off the acid. Semi-refining oil and soapstock are got.

2) Semi-refining oil decolorizing

This part uses the clay to decolorizing the semi-refining oil. First, the oil and clay are mixed. After a short time, the color will get out from oil. Then the vibrating filter will separate the oil and clay. The oil get from this step is called decolorizing oil.

3) Decolorizing oil deodorizing

The function of this part is move the odour from the oil. The steam will play an important role in this processing. For most materials, this is the last step and edible oil have got.

4) Dewax

For rice bran oil, sunflower oil and corn embryo oil need the dewax process. The oil contains a lot of wax, which comes from the skin of oil seed.

3. Functions of main parts

(1) Refining section: used to P-acid de-gumming, alkali refining de-acid and water rinsing.

(2) Decoloring section: used to remove off pigments, bleaching oils and grease dehydrate.

(3) Deodorizing section: to remove off the odor components in oil.

(4) Dewax: used to remove off the wax in the oil, in order to get the high quality oil.

(5) Heattransfer oil stove: supply each device production needing heat enerLD, temperature reach above 280°C.

(6) Steam generator: produce the needing steam for de-odoring and distillation.

(7) Vacuum pump: supply needing vacuum for dehydrate, de-color, de-odor. Vacuum degree can reach above 755mm Hg.

(8) Press filter: filter clay, filter out clear oil.

(9) Air compressor: blow dry bleached clay, blow empty the leftover oil in the press filter.

4.Technical performances of RBD oil

Refinery line
Crude oil refining workshop is through take off impurity, Degumming, decoloring, deodorization, removing wax, fractionation etc, to achieve different standards edible oil.
At present, Having four grade of edible oil, different oil grade have different requirement for quality and machines.
Flow chart of refinery
Crude oil——→Take off impurity——→Degumming——→Decoloring——→

Deodorization——→Removing wax——→Fractionation——→Crystallization
Advantage:
1.After refining the impurity of oil must be less than 0.2%
2.Recycling system save power and money
3.Lower oil waste
