Oil Refinery



Washing And Vacuum Drying Section

Washing And Vacuum Drying Section

Washing And Vacuum Drying Section

The system is designed to Neutralize and water washing the crude oils. The Neutralizing System is used as the first step in chemical refining referred to as Neutralizing.


Neutralizing : The oil is delivered to the system by the Feed Pump. It is heated to 65 - 70 C in the Crude Oil Economizer by hot oil from down-stream bleaching/deodorizing operations or, when necessary, by steam in the Feed Heater mixed with pre calculated quantity of Phosphoric acid in an gum conditioning mixer and fed to mixer where the pre calculated quantity of water is added . Oil water mixture is fed to hydration tank to give sufficient residence time for gums to agglomerate on hydration. This oil is then pump to separator where the oil and hydrated gums are separated and pumped to storage or disposal or gum drying plant in case of soybean gums.

 

Water Washing : The residual soap in the degummed & neutralized oil is reduced by water washing. In this case the oil from the separator is heated to about 95 C in the Washing Heater and then mixed with 10 - 15% soft water in the Wash Mixer. After a few minutes retention in the Wash Reactor the wet oil enters the Wash Water Separator. The washed oil, typically containing under 100 ppm soap and with a reduced level of phosphorus, is sent directly to bleaching as described above. The heavy phase soapy water is collected in the Recovered oil tank and drained to Effluent treatment.

 

Vacuum drying : Washed oil is fed continuously to the Vacuum dryer and sprayed through specially designed nozzles. The vacuum dryer is kept under a vacuum of 70 torr. The dried oil from the vacuum chamber is continuously pumped out by pump to intermediate storage tank.



Degumming System

Degumming System

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.



Bleaching Section

Bleaching Section

Bleaching Section

The feed oil (acid conditioned, degummed / neutralized & washed) enters the Bleaching Section via a Bleaching heater where the oil is heated up to Bleaching temperature and discharged into the slurry mixer. A valve dosing system proportions Bleaching Section. The earth is introduced under the oil spray in the mixing chamber for improved mixing so that earth does not enter the Bleaching Section. The earth adsorbs any residual gums and soap as well as trace metals, color bodies and other polar impurities. The Bleaching Section has multiple agitated compartments and operates under vacuum to ensure complete moisture and air removal. The dried oil and earth mixture is discharged by the Bleacher Discharge Pump to one of the Filters where the spent earth is removed. The filtered oil is collected in the Filtrate Receiver. The Bleached Oil Pump sends the oil to Deodorizing via one of the alternating Polish Filters.

 

Filter Management : The standard Bleaching Section is based on the use of two filters of which one is on line while the other is being cleaned and prepared for the next cycle. When a filter has reached its maximum capacity, as indicated by high feed pressure, it is taken off line for cleaning and replaced by the other filter.

 

The cleaning procedure begins by first pressurizing the filter with steam to expel residual oil into the Recovered Oil Tank and dry the spent filter cake. The oil recovered from the filter cake is collected in the tank and can usually be recycled to the Bleacher. After drying, a bottom discharge valve on the filter is opened and the leaves pneumatically vibrated so that the spent cake is dislodged and discharged via a hopper. The filter is then closed and readied for the next batch. Before going on line again it can be pre-coated with filter aid and/or bleaching earth in order to seal the filter leaves and minimize clogging.

 

The adsorbents are mixed with bleached oil in the Precoat/Heel Tank and applied to the leaves by circulation with the Precoat Pump. When not using filter aid or “off-line” pre-coat, the empty clean filter is filled and put on line while the other filter is still in operation. The filtrate from the clean filter is recycled back to the Bleacher until the filter is pre-coated with bleaching earth and the oil is clear. After this the full flow is switched to the new filter.



Oil Deodorizing Machinery

Oil Deodorizing Machinery

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.



Physical Refinery

Physical Refinery

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.
