Main Processes Introduction
Hydration Deguming & Alkali Refining Deacidification Process
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 or citric acid from phosphate tank in the gas mixture (M401), and then enters the conditioning tank (R401) to make the non-hydratable phospholipids in oil change into the hydratable phospholipids.
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-mixed oil and water in the mixer is heated to 90-95°C by the heater, and then enters the wash separator to separate the remaining soap and most water.
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 90 °C should be sent to vacuum 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 Refining De colori ng P rocess
The main function of d ecolori ng process is to remov e oil pigment , residual soap grain and metal ions. U nder negative pressure , the mechanical mixing method combined with steam mixing will improve the decoloring effect.
The degummed oil firstly enters into the heater to be heated to the appropriate temperature (110 °C ), and then goes to the bleaching earth mixing tank. The bleaching earth is delivered from the low bleaching box to the temporary tank by wind. The bleaching earth is added by automatic metering and is interlockingly controlled with the oil.
Continuous De color ing P rocess Features :
1 . The oil fully contacting with the decolorant can improve the decolorization efficiency and reduce the usage of decolorant ;
2. The continuous and uniform material flows will balance the decoloring time and avoid the recovery of grease oxidation and acid value.
3. The special mixing structure of decoloring tower won't cause the material dead area, which can avoid the adsorbent sedimentation and pipe blockage.
Continuous Refining Deodorizing Process
The qualified decolored oil enters into the spiral plate heat exchanger to recover most of the heat, and next goes to high pressure steam heat exchanger to be heated to the process temperature ( 240-260°C ) and then enters the deodori zation to wer.
Automatic Control System
Our company has applied the automatic control system with advancedness, security, reliability into the pretreatment, extraction, refining and fractionation in large oil plants. For its application in automatic control system, it can control the production in the entire workshop and monitor the operational status of each device by controlling the computer terminals in the room. One person only can operate the entire workshop, with efficient production management. It has reduced the production cost greatly and improved the management efficiency.
