Main Refining Processes:

 

De-mixed, degumming, dehydration, deacidification, decolorzation, dewaxing  and deodorization.

 

1. Degumming :Usded to neutrilizing ,and water washing,to rid off the acid .
2. Deodorization:Used to rid off the fetid smell/odour of oil by steam understand of high temperature.
3. Soap feet vessel:Used to refine the oil sediment from oil refiner,to get some oil from oil sediment .
4. Hot & Alkali water tank:Used to produce hot water heated by the steams ,also alkali water from the alkali dis-voling tank,for adding into the oil refiner.
5. Alkali dis-voling tank :Used to produce the alkali water .
6. Steam separator:Separating the steam to oil refiner,de-colorer,deodorizer,hot water tank,etc.
7. Decoloring vessel:Used to rid off the color of the oil
8. Clay tank:Store the medication decolored for the clay tank.
9. Transfer hot oil furance:Contact to the deodorizer part , producing high temperature (280 degrees orso) for  deodorization.
10. Gear pump:Pump oil into kinds of vessel and tank.
12.Water pump:Pump cool water into water tank.
13. Transfer hot oil pump:Pump hot oil into transfer oil furance.
14. Cooling water tower:Cool water for cooling oil ,recycling using.

 

15. Dewaxing /winterization / fractional

 Continuous Decoloring Process 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. 

 4. The continuous airtight efficient filtration equipment has realized the automation of cake discharge and reduced the labor intensity. 

 5. The advanced drying technology can reduce the oil content in filter cake. 

 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 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 peroxide value of the oil to zero. Oil from the deodorization tower enters into the heat exchanger to recover most of the heat and makes further heat exchange with crude oil, and then is cooled to 80-85°C through the cooler. Add the required antioxidant and flavor agent, and then cool the oil below 50°C and store it.  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.
