Crude Corn oil is refined through chemical Refining Process. The following are the process steps for Refining corn oil:
Corn Oil Refining Plant Process:
Degumming
The crude oil is pumped to the Neutralizer from the storage tank. In Neutralizer the oil is heated up to 60-70 degree C 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.
Continuous Acid / Water de-gumming /Neutralization
The crude oil is first pumped to the COT-1 from the storage tank and oil is heated up to 70 degree C by means of PHE through a Flow Meter, and weak solution of phosphoric acid and water is added continuously and the material enters to Hydration tank for maturation of phospholipids. This is then separated through a centrifuge continuously. The degummed oil is transferred to another COT-2. The degummed oil from COT-2 is pumped through flow meter to PHE to attain the reaction temperature, then heated oil enters the Disc Mixer, where calculated amount of caustic soda solution is added, the soap stock is separated through the same centrifuge (depending upon the F.F.A. of oil which reacts with the free fatty acid forming soap). The Neutral oil is transferred to the COT 1. The Washing of Oil is also done through the same centrifuge. The washed oil is passed through the Vacuum Dryer to reduce the moisture and stored in NOT tank from there it is pumped to the Bleaching section.
Continuous Double Deck Bleaching
De-gummed 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 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.
Dewaxing with Spec-Crysta Tower
De-waxing is the process to cool the oil at the temperature, at which wax converts in solid form (actually in slurry form) which oil remains in liquid form as it is. For this oil cooled slowly and step by step, with cold water and then chilled water. The bleached from BOT is pumped continuously with stream of flow to the series of crystallizers, where oil is cooled slowly and steadily in counter current manner, so as to crystallize the wax for the purpose of easy filtration. After this oil is transferred to the maturator, which is again in series to the crystallizers, here oil maturated in terms of temperature it will be increased or decreased as per requirement to assure the crystal formation of wax. Finally, this oil is filtered by the filter presses.
Deodorization
Deodorizer is multi-compartment vertical vessel, where each tray are specially designed which Ensures uniform distillation of odoriferous substances. Oil is overflows from tray to tray. Specially designed trays provide sufficient mass transfer surface for effective removal of volatile matters. Flow control system at the outlet of the deodorizer, ensures the maintenance of required level at the bottom tray. The steam used for stripping off volatile matters in the oil is distributed evenly and intensively, the steam meets the deodorized oil. Stripped off the volatile matter and rises through the vacuum. Stripping the volatile matter from the oil. The counter-current flow of steam and oil like this in specially designed trays lower steam consumption, than the conventional deodorizers. The deodorized oil leaving regenerative heat exchanger and finally cooled by water in heat exchanger finally this oil is passed through the alternatively operating set of polishing filters. VAPORS SCRUBBING The volatile matters consisting of free fatty acid and other odoriferous substances stripped from the deodorizer are led to the vapor scrubber located at the outside of the deodorizing column. In the scrubber, volatile material rises through the bed of pall rings and meets liquid fatty acid sprayed from the top. Vapors are condensed, cooled, and then recalculated to condensed fresh vapors. Excess distillate collected is led to the storage tank, whenever high level reached in storage space below the scrubber. Fatty acid scrubber is specially designed for minimum carryover of fatty materials, to the vacuum system.
Benefits of Spectec Deodorizing Section :
- Vacuum balance tray design ensures zero vapour logging i.e. effective distillation.
- Online fatty spraying also helps for zero vapour logging which ensures maximum vapour 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.
