Refineries have always been our forte as far as the oil processing industry is concerned. Given the major changes that have come about in the manufacturing and installation of oil refinery in the last few years, we have also gained expertise in providing cost efficient and well equipped oil refinery of various kinds. Our company offers various types of refineries like the vegetable oil refinery, crude oil refinery, continuous physical refinery and continuous chemical refinery. Only high raw materials are employed in the production stage to make sure that high international standards are met. Also, a team of experts conducts a series of quality assurance tests in order to make sure that the final product is high on performance and efficiency.
The system is designed to degum crude oil. The Degumming System will generally produce oil with lower levels of residual phosphatides and less residual pigments and therefore require less bleaching earth in bleaching as well as help generate finished deodorized oil with a lighter color and longer shelf life. The Degumming System is illustrated on the attached drawing.
The oil is delivered to the Degumming System by the Feed Pump. It is heated to 65 - 70 C in the Crude Oil Heater by steam in the Feed Heater and then mixed with acid solution in the Mixer. The mixture is delivered to reaction vessel with agitator for completion of reaction. The mixture from reaction vessel is cool down to 25-30 Deg C and mixed with desired quantity of water. This mixture is delivered to hydration vessel with agitator for coagulation of phosphatides..
The coagulate mass is transferred to centrifugal separator through heater to heat the oil 70-80 Deg C. for separation of gums from oil. Separated gums are collected in gum tank and delivered to storage or to desolventizer toaster. Degummed oil from separator is transferred via heat exchanger to vacuum drier for removal of moisture from oil. Dried oil from drier is delivered to dried oil storage tank.
The system is designed to Physical Refinery, i.e. pre treat, bleach, strip and deodorize Palm olein. In the Pre Treatment section phosphoric acid is added to crude oil, which reacts with the gums present in oil. The Physical Refinery is based on treatment with bleaching earth followed by filtration. The process design is illustrated on the attached drawing. The High Efficiency Physical Refinery can be used for deodorizing of neutralized oils as well as stripping and deodorizing of high FFA oils as part of physical refining. The Physical Refinery is illustrated on the attached drawings.
Merits of Continuous Physical Refinery :
Continuous bleacher with vacuum-sealed bleaching earth dosing arrangement is provided for a very quick and efficient bleaching of the oil
Adequate Plate Heat Exchangers and other heat exchangers are provided to enhance maximum heat recuperation of the out going oil form the deodoriser and thus reduces the steam consumption to a bearest minimum
An additional heat exchanger is provided to rescue the heat of out going thermic fluid for the feed oil to the stripper and thus reduce the total heat load on the stripper
Vertical packed type D.O. ensures efficient deodorisation of the oil with minimum steam consumption
4 Stage Mazda make high vacuum equipment is provided to have suitable vacuum (3 torr) for the process
Three stages of filtration of the oil are provided before reaching to the final holding tank to assure the best quality of the refined oil
Plate and frame type heat exchangers are mostly used for less space consumption, less maintenance, and efficient heat transfer
Complete automation is provided to assure continuity of the process and less manpower requirement
