Palm Oil Semi-continuous Refining Process:

1.Process Introduction

Palm Oil→water washing and alkali refining→dephosphorization deguming→decoloration→continuous deodorization→to fractionation and dewaxing workshop

2.Brief introduction for the equipment

A.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,it can decrease the acid value in oil and separate the impurity ,phospholipid which will enter into soap stock..The oil can be refined further.

B.Bleaching pot:Also named bleaching, dewatering pot,it removes water from oil by vacuum.The bleaching earth is breathed into bleaching pot ,after stirring,filtrated by filter and change the color of the oil.

C.Vertical blade filter machine:Equipped with vertical leaf filter to remove used bentonite from the oil, operating conveniently and continuously , low laboring tense, keeps environment well, keeps oil residence in deposable bleaching earth in low level.

D.continuous deodorization(Stainless Steel)

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. Such volatiles as FFA from the deodorizing system are separated by the packing catcher, and the separated liquid is FFA at low temperature (60-75°C). When the liquid level in the temporary tank is too high, the oil will be sent to the FFA storage tank.
