Oil Refinery

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.

Deodorisation Oil Mill Machinery is continuously pumped from the Feed Tank by the Deareator Feed Pump. The Deodorisation Oil Mill Machinery is pre-heated in the Deaerating Economizer by outgoing deodorized oil followed by the Deaerating Heater (if necessary) before entering the Deaerator. The vessel is under full vacuum, so that residual air is reduced to an absolute minimum. The Deaerator Discharge Pump sends the oil through a Heat Economizer where the temperature is increased by hot deodorized oil. The Deodorisation Oil Mill Machinery is heated to full processing temperature in the Vacuum Heater by thermal fluid from the Thermal Oil Heater. A portion of the free fatty acids in the oil will be flashed off as the oil temperature increases.

 

Stripping : The Deodorisation Oil Mill Machinery enters the Packed Column, which is filled with special structured packing so that the oil is distributed into a thin film and is evenly agitated by stripping steam flowing counter currently from the bottom of the column. As a result, free fatty acids and other remaining volatile impurities in the oil are evaporated and removed with the steam. The residence time in the column is only a few minutes. The bulk of the free fatty acids along with aldehydes, ketones etc. in the oil are quickly stripped off before any heat induced permanent damage has been done.

 

Deodorizing : The stripped oil from the column flows into the Deodorizer where it flows through the channels of a series of vertically stacked compartments (trays) while agitated by stripping steam. The prolonged thermal action breaks down carotene and other color bodies, resulting in a lighter oil color. Also, the amount of remaining free fatty acids in the oil is reduced to an absolute minimum. The stripping steam passes through the packed column and no separate steam is required in the stripping column. The maximum retention time in the Deodorizer is 70 minutes.

 

Cooling : The deodorized oil is discharged into the Deodorizing Economizer and cooled by incoming oil. The Deodorisation Oil Mill Machinery is then discharged by the Product Pump and further cooled to storage temperature in the Deaerating Economizer and Product Cooler. The anti-oxidant is mixed with oil in the Deodorizing Economizer. The finished oil is finally sent to storage via one of the alternating Product Filters.

 

Distillate Recovery : Fatty acids and other materials, evaporated from the Deodorisation Oil Mill Machinery, are condensed by contact with recycled and cooled distillate in the Vapor Scrubber. The distillate is circulated by the Distillate Pump via the Distillate Cooler where it is cooled by cooling water. Accumulated distillate is discharged from the Scrubber to storage.

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

  • The complete plant layout and equipments are designed and arranged for better space utilization, operator friendly and less man power requirement

The Vertical Cylindrical vessel with Tray Type Deodorizer in Stainless Steel construction, provided with sparging steam arrangement, light sight glasses designed for continuous operation with provision for external oil heating system to deodorization by thermal oil / high pressure steam. The final product produce will be international quality with Minimum transacid contents.
