continuous oil refining equipment Main Processes Introduction

continuous oil refining equipment Hydration Deguming & Alkali Refining Deacidification Process:

Neutralization: the crude oil is output by the oil feed pump from the oil tank, and net enters the crude oil heat echanger to recover part of heat after metering and then is heated to the required temperature by the heater. After that, the oil is mied with the metered phosphoric acid or citric acid from phosphate tank in the gas miture (M401), and then enters the conditioning tank (R401) 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 (90C) suitable for centrifugal separation to remove the phospholipids, FFA and other impurities in the crude oil. Then the oil goes to the washing process.

Washing: there is 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 C higher than the oil generally. To achieve more stable washing effect, add phosphoric acid or citric acid when washing. The re-mied oil and water in the mier is heated to 90-95C 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.

rapeseed oil refining , mini oil refining machine and continuous oil refining equipment 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 90C should be sent to rapeseed oil refining , mini oil refining machine and continuous oil refining equipment drier to remove the moisture, and then the dehydrated oil goes to the decoloring process. Finally, pump out the dry oil by canned pump.

continuous oil refining equipment Decoloring Process:

The main function of decoloring process is to remove oil pigment, residual soap grain and metal ions. Under negative pressure, the mechanical miing method combined with steam miing will improve the decoloring effect.

The degummed oil firstly enters into the heater to be heated to the appropriate temperature (110C), and then goes to the bleaching earth miing tank. The bleaching earth is delivered from the low bleaching bo to the temporary tank by wind. The bleaching earth is added by automatic metering and is interlockingly controlled with the oil.

The oil mied with the bleaching earth overflows into the continuous decolorizer, which is stirred by nonpowered steam. The decolored oil enters into the two alternate leaf filters to be filtered. Then the filtered oil enters thedecolored oil storage tank through the security filter. The decolored oilstorage tank is designed as the rapeseed oil refining , mini oil refining machine and continuous oil refining equipment tank with the nozzle inside, so as to prevent the decolored oil contacting with the air and infrapeseed oil refining , mini oil refining machine and continuous oil refining equipmentcing its peroide value and color reversion.

continuous oil refining equipment Deodorizing Process:

The qualified decolored oil enters into the spiral plate heat echanger to recover most of the heat, and net goes to high pressure steam heat echanger to be heated to the process temperature (240-260C) and then enters the deodorization tower.

The upper layer of combined deodorization tower is the packing structure which is mainly used to remove the odor producing components such as free fatty acid (FFA); the bottom layer is the plate tower which is mainly for achieving the hot decoloring effect and reducing the peroide value of the oil to zero. Oil from the deodorization tower enters into the heat echanger to recover most of the heat and makes further heat echange with crude oil, and then is cooled to 80-85C through the cooler. Add the require antioidant and flavor agent,and then cool the oil below 50C and store it. Such volatiles as FFA from the deodorizing system are separated by the packing catcher, and the separated liquid is FFA at low temperature (60-75C).

When the liquid level in the temporary tank is too high, the oil will be sent to the FFA storage tank.
