The feed oil is heated to 65-70°c in the economizer by outgoing deodorized oil followed by feed heater (during start up). Concentrated phosphoric acid (0. 05 - 0. 10%) is injected by the acid metering pump and intensively mixed with the oil in the acid mixer before entering the conditioning reactor. The oil is discharged into the slurry mixer above the bleacher. A valve dosing system proportions bleaching earth. The earth is introduced under the oil spray in the mixing chamber for improved mixing so that earth does not enter the bleaching vacuum system. The oil is heated up to bleaching temperature in the first compartment of bleacher. The earth adsorbs any residual gums as well as trace metals, color bodies and other polar impurities. The bleacher 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 the bleached oil tank via one of the alternating polish filters.

 

Filter management : The standard bleaching system 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.

The feed oil (acid conditioned, degummed / neutralized & washed) enters the bleacher 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 earth. The earth is introduced under the oil spray in the mixing chamber for improved mixing so that earth does not enter the bleaching vacuum system. The earth adsorbs any residual gums and soap as well as trace metals, color bodies and other polar impurities. The bleacher 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.

Crude 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 a gum conditioning mixer 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 pumped 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.

In the case of water degumming process, crude oil is heated to required temperature in the plate heat exchanger, mixed with pre calculated water through mixer and fed to the hydration tank for sufficient residence time for gums to agglomerate. Then it is pumped to separator where oil and hydrated gums are separated.

Water degummed oil from separator is pumped to plate heat exchanger where oil is heated to neutralization temperature i. E. Around 80 to 85 deg c. The hot oil is fed to mixer with requisite quantity of phosphoric acid where oil and phosphoric acid is allowed a brief holding time and the precipitation of trace metals take place.

Degummed oil is fed in to mixer where it is mixed with calculated quantity of caustic soda solution of suitable strength. Free fatty acid reacts with caustic soda to form soap . The reacted oil is sent to the gum/soap separator . The precipitated impurities are removed from the oil as water based heavy phase referred to as soap stock. The gums/soap are collected in the heavy phase receiver and sent to intermediate storage by the heavy phase pump.
