Castor Oil Processing Plant Manufacturer
Castor Oil Refining constitutes of the following process steps :
Process Description:
Degumming
The crude oil is pumped to the Neutralizer from the storage tank. In Neutralizer the oil is heated up to 60-700C by means of the live and indirect steam provided in to the Neutralizer. The required quantity of Phosphoric acid is slowly added and allow this to react for 30 mins and after that raise, the temperature to 70 degrees centigrade, the required amount of caustic is added to neutralize the free fatty acid. Allow this to react for 10 mins and give a hot water wash, to allow the soap stock to settle. After 4-6 hours, soap stock is drained off. After removing soap stock give a hot water wash to remove the traces of Soap.
Bleaching
The crude oil from bulk storage tank, is directly pumped to the oil/oil heat exchanger where incoming crude oil is getting heated by the outgoing refined oil, further this oil is going to buffering tank which insures the constant flow of incoming and outgoing oil, it is also equipped with mechanical agitator and steam heating coils. Where oil heated up to the required temperature as process demands. And mixed properly for the purpose of HOMOGENATION. Further this oil is heated with heat exchanger and pumped to the hydration tank, where calculated amounted of hot water is being added continuously, to maturate the Hydratable gums. In continuous process this hydrated water degummed, Gums are separated in the self-cleaning centrifugal separator.
This degummed oil is further heated by a steam in heat exchanger, then mixed properly with hot water with the help of knife mixer and getting water washed by a centrifugal separator. Finally, this water washed oil is dried under vacuum in a vacuum drier.
Continous Double Deck Bleaching
De-gummed castor Oil form NOT is pumped to the BLEACHER at the same time part of oil is carried to the SLURRY TANK oil is cooled before passing to slurry mixer. Pre-calculated amount of bleaching earth is added in the slurry mixer; this slurry is sucked by means of vacuum to the bleacher.
After proper holding & mixing this oil is sent to the alternative operating set of PRESSURE LEAF FILTER after this filtration oil is again filter by alternative operating set of polishing filters. Then it is cooled by shell and tube cooler before it reaches to the BOT.
Benefits of Spectec Double Deck Bleaching Section
- Oil Earth Mixer is specially designed with higher mixing speed which ensures quick & effective mixing.
- Continuous Bleacher is a combination of Dry & Wet bleaching which makes it multipurpose.
- Simple & low maintenance automations.
Deodorization
Deodorizing is nothing but The DISTILLATION process. In which fatty acid is distilled from oil. Under high temperature condition and in presence of high vacuum, with the help of sparging & agitation steam. Further this fatty acid in vapors form, is condensed & recovered in liquid form by the vapors scrubbing system.
Benefits of Spectec Deodorizing Section
- Vacuum balance tray design ensures zero vapor logging i.e. effective distillation.
- Online fatty spraying also helps for zero vapor logging which ensures maximum vapor to carry to the scrubber without distilling in trays.
- Effective de-aeration increases the heat exchanging efficiency, because of zero dissolved air.
- Efficient re-generative heat exchanging trays ensures maximum heat recovery and addition deodorizing time.
- Counter current flow (oil/steam) design increase the tray efficiency for better deodorization & distillation.
- Vacuum sealing arrangement for power failure.
- Simple & low maintenance automations.
