Refining Process Description:

 

Calibrated crude oil is pumped to pipe Filters; then filtered oil is sent to heat exchanger. Heated oil is mixed with acid in the mixer before going to the reaction tank. After reaction and cooling, the oil enters another mixer to mix with caustic alkali liquid to neutralize. The neutralized oil enters the centrifugal to separate soap from oil. Separated oil still contents some quantity of soap that should be removed. By mixing with hot water, the oil is washed. Then a centrifugal is used to separate the water with residual soap from oil.

 

 

De-gummed and neutralized oil is pumped into vacuum drier, and then dried oil is cooled by a heat exchanger and sent into a storage tank. De-gummed and neutralized oil is sent to bleaching section to bleach. Oil to be bleached is pumped to mixed tank and heating tank separately. A proportion of oil to be bleached is pumped into a mixing tank to mix with dosed bentonite, and another part of oil to be bleached is pumped to the heater. The mixture and the heated oil go into the bleaching tank to de-colourize.

 

 

Consequently, the mixture of oil and betonies is pumped into leaf filter to remove deposable bentonite.

Parallel leaf filters make it possible to perform continuous operation of bleaching. Filtered oil is pumped into the storage tank after being cooled in a heat exchanger and filtered safely.

 

 

The principle of winterization de-waxing is that the freezing point of wax and oil is different. Under the condition of given time and temperature, wax can be crystallized by lowering the temperature of the oil. By means of mechanic filter, wax and fluid oil is separated. The final product will reach the condensation experimental standard. The aim of winterization de-waxing is to remove the wax with high melting point which might cause oil to turbid in low temperature.

 

 

Deodorization section is to remove the unpleasant odor from bleached oil. Certain amount of citric acid liquid is added to the oil to be deodorized to chelate the metal ion in oil. The oil then enters a deaeration tank to remove air in the oil by high vacuum. Then oil is pumped into a heat exchanger to raise temperature with hot deodorized oil; SUNFLOWER OIL is heated further by mineral oil to raise the temperature to 240 ⁰ C ~ 265 ⁰ C . The heated oil goes into the deodorizer tower from the top of flash sector; mixes with the rising steam to strip low molecular organic compound. Oil flows down to the bottom of tower to perform pigment decomposition. The flavor of oil is improved. Oil is pumped into the main sector of deodorizer tower to further remove free fatty acid (FFA). The vapor goes into FFA stripping sector to exchange heat; the condensed low molecular compound goes into the recycling FFA stripping system. The deodorized oil from the bottom of deodorizer tower is pumped out to exchange heat with oil that comes out from the deaeration tank, and then goes to a cooler. Finally, oil is filtered by polished filter. Final product is sent to final oil tank, which can be sold as salad oil.
