Brief introduction of oil refinery

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.

 Impurities present in the Oil

Gums: Gums are phospholipids. There are two types of gums present, hydratable and non-hydratable. Hydratable gums are removed during degumming steps.

Hydrolysis Products Of Oils: Like Diglycerides and monoglycerides and free fatty acids. These are removed during neutralisation step.

Proteineous Matter, Carbohydrates, Resins: These are removed during neutralisation step.

Colouring Matter: Pigments such as chlorophyll (green colour) carotene (red colour), anthophyll (yellow colour) and gossypol (orange colour). These colour bodies which impart distinct colour to the oil are removed during neutralising and bleaching steps.

Odour-causing Chemicals: They are generally present in small quantities but their presence imparts strong, sometimes objectionable odour to the oil. These substances are volatile in nature and removed by deodorisation step.

Waxes: Some oils like sunflower contains appreciable amounts of waxes. Waxes are high melting esters of fatty alcohol with long chain fatty acids. These are removed by dewaxing step.

Specific function of each section of oil refinery

Degumming section:Degumming is the first and basic step in the crude oil refinery plant, degumming process aims to removing the gum impurities in the crude oil to make it suitable for further refinery process, hydration degumming and special acid degumming are the two main methods.  

Deacidify section:The deacidify system uses versatile neutralization technology, which is developed to deal with oilseeds of different species and qualities in the oil refining plant, it can realize both degumming and neutralization processes by adding alkali, water and acid, then with FFA, crude phospholipids and moisture all removed, the oil and by products (soap foot, phospholipids) are separated.

Bleaching section: The oil bleaching is also named decolorization in oil refinery processes. This process’s main purpose is to remove the product of oxidation, pigments, phospholipids, soap materials from the oil. In the oil refinery plant, this process can improve the oil color as well as supplies high quality oil for the deodorization process.

Deodorization section:Deodorization section is very crucial in edible oil refinery plant in first grade oil production as it improves the flavor of the oil; the quality of deodorization equipment has great effect to the oil quality.
