What is Refining?

The crude oil obtained either from expellers or solvent extraction plant contains impurities, which must be removed to

make the oil edible, more palatable and stable against rancidity upon storage. The process of removing these

impurities is called refining.

Refinery methods of oil refinery:

1)chemical refining 2) physical refining 3)chemical-physical refining

The classical alkaline refining method usually comprises the following steps:

The classical alkaline refining method usually comprises the following steps:

Step 1.Degumming with water to remove the easily hydratable phospholipids and metals.

Step 2.Addition of a small amount of phosphoric or citric acid to convert the remaining non-hydralable phospholipids (Ca, Mg salts) into hydratable phospholipids.

Step 3.Neutralising of the free fatty acids with a slight excess of sodium hydroxide solution, followed by the washing

out of soaps and hydrated phospholipids.

Step 4.Bleaching with natural or acid-activated clay minerals to adsorb colouring components and to decompose hydroperoxides.

Step 5.Deodorising to remove volatile components, mainly aldehydes and ketones, with low threshold values for

detection by taste or smell. Deodorisation is essentially a steam distillation process carried out at low pressures

(2-6 mbar) and elevated temperatures (180-220°C).

Regard refinery flowchart:

For some oils, such as sunflower oil or rice bran oil, a clear table product is obtained by a dewaxing step or

crystallization of the wax esters at low temperature, followed by filtration or centrifugation.

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. 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.
