Process Description of Edible Oil Refinery Plant

As per the today market research it is being concluded that the market demands the refined edible oil with characteristics such as bland flavour and odour, clear appearance, light colour, Long Shelf Life, Suitable for frying since the Crude Oil obtained does contains many harmful factors like free fatty acids (FFA), sediments, gums, odoriferous material & other impurities.

Goyum with an experience of more than 4 decades in the Edible Oil Industry have worked unremittingly in more than 50 countries of the world and have developed overall solutions for the Edible Oil Refinery needs of the Customers.

The refining of edible oils & fats is required after solvent extraction since the Solvent Extracted Crude oil does contains inherent harmful constituents like Free Fatty Acids (FFA’s), gums, sediments, odoriferous and colourings material, phosphatides, hydrocarbons, traces of pesticides & heavy metals etc.

Following sections depending on the nature of the oil either soft or hard oil: enquiry

Degumming, Neutralization & Water Washing

Degumming is a process of removing phospholipids to improve its physical stability and facilitate further refining. Phospholipids may lead to the dark colored oil and they may also lead to off -flavour. Free fatty acids, pigments and other impurities are also partially removed by degumming.

Goyum follows different type of degumming processes like Water Degumming/Acid Degumming/ Enzymatic Degumming. These processes are being selected based on methods of processing, chemicals used and the content of phosphatides in the crude vegetable oil.

Neutralizing of the free fatty acids with a slight excess of sodium hydroxide solution, followed by the washing out of soaps and hydrated phospholipids.

Technological Highlights

  • Efficient Design
  • Less utility Consumption
  • Less Maintenance Cost
  • Better Process
  • Efficient Removal of Hydratable and Non Hydratable Gums.

The bleaching of edible oils and fats is an important part of the refining process of crude oils and fats. It does remove the several contaminations which impacts adversely the physical appearance and quality of the oil. Generally the oil after degumming / neutralization also does have impurities in various quantities. Many of these impurities have to be removed from the oil to achieve the high quality oil for the edible use.

Bleaching with natural or acid-activated clay minerals to adsorb coloring components and to decompose hydro peroxides.

Goyum’s unique design of the bleacher keeps bleaching earth in full suspension due to which there is no dead areas inside the bleacher which in turn gives lower utility consumption.

Technological Highlights

  • Lower Bleaching Earth Consumption
  • Uniform Mixing of Oil & Earth
  • Maintenance Free Bleacher
  • No Dead Area in Bleacher
  • Lower Percentage of Oil in Spent Cakes

Winterization / Dewaxing Plant

Winterization / Dewaxing are almost the same process. This process is applied to remove small quantities of solids from oil that would normally cause cloudiness of the oil when kept at refrigeration temp.

These substances can be saturated glycerides or waxes. Waxes are esters for fatty alcohol and fatty acid, which have a very low solubility in oil. There quantity is different in different oils.

Generally varies in between 48-2000 ppm. In order to obtain oil with good cold stability, the wax contains needs to reduce to the level of about 10 ppm. In this process cooling rate & agitation are carefully controlled to promote the formation of nuclei that will serve as the sites for crystal growth.


Deodorization is done to remove the volatile components, mainly Aldehydes & Ketones, with threshold values for dictation by taste or smell. Deodorization is essentially a steam distillation process carried out at low pressure 2-6 Kg/Cm2 and elevated temp range of 180-220°C.

The entire process is done under high vacuum. The smell is removed in the deodorizer. The FFA is also removed in the Physicaltype deodorizer.

Technological Highlights

  • Max. Heat Transfer Area
  • Lower Steam Consumption
  • Zero Contamination
  • Elaborated and Efficient Design for the Removal of Fatty Acid in Physical Type Deo
  • Longer Self Life of Oil
  • No Maintenance

Palm Oil Fractionation Plant

After the bleaching section the oil is first cooled by cold Fractionated oil for maximum regeneration of heat. Then the same oil is cold by cooling tower water up to 40 C to 45 C. Then this oil is cooled by outgoing chilled fractionated oil from the filters. This oil is then chilled to de-waxing temp and feed to Crystallizers. In the crystallizer proper residence time is given with maintaining the temperature of the oil, which results in formation of wax / stearin crystals and residence time, will give proper growth to the crystals. This mixture is then feed to the Filter Press for the removal of the stearin.

Technological Highlights

  • Large heat transfer area with regard to the oil charge in the Crystallizers.
  • Optimal position of the heat exchange surfaces with regard to the impellers and therefore to the oil circulation in the vessel.
  • All parts of the processed oil are really driven too close to the heat exchange surfaces.
  • The cooling program is accurately followed.

Hydrogenation Plant

Hydrogenation which is also called FAT MODIFICATION is a unique 3 phase process system; Solid (Nickkle catalyst), Liquid (Oil) and Gas (Hydrogen). Further a selective reaction, by bringing gas-hydrogen, liquid-oil to the solid Ni- Catalyst and this technological concept formalized on Engineering Design. Hydrogenation is accomplished by reacting oil with hydrogen gas and in the presence of heat and metal catalysts, e.g. nickel.

Technological Highlights of Hydrogenation

  • Improved Gas Dispersion Low Specific Energy Consumption
  • Steam Production
  • Fully Automated Plant and Reliable Controls
  • No venting required as hydrogen is entirely consumed at the end of the reaction

The technology design of the splitting tower allows a splitting degree well above 99% heating by direct steam injection is under automatic temperature control. The tower is operating at 60 Bar and is composed by three main section:

  • Central section where splitting occurs.Top section of heat exchanger where the outgoing Fatty Acids preheat the incoming water and are cooled.
  • Bottom section where the outgoing sweet water preheat the incoming Fat.

Fatty Acid Distillation and Fatty Acid Fractional Distillation

Technology fatty acids distillation unit is a very compact design where condensation and scrubbing are incorporate in the column itself.

Operating temperature are kept to minimum due to very low pressure drop of the tower. The distiller is a structured packing tower. According to the raw materials the process may contemplate a precut column.

Maximum heat recovery is achieved by generating low pressure steam.

Fatty acids of different length are fractionated at the requested purity in several columns.


Technology glycerine refining process can guarantee pharmaceutical grade products matching all international standards.

Glycerine treatment Concentration and Distillation units are able to process all kind of crude glycerine coming from sweet water. Spent Lye and Biodiesel.
