Soybean Oil Refinery Plant Manufacturer
Spectec techno projects Manufacturer, supplies, and exports highly energy efficient, customized, cost-effective, turnkey projects for Soya oil Refinery plant/ Soya bean oil processing plants with a focus on higher productivity lower operational cost, optimize the use of by-products, and relatively shorter payback period.
Soya oil Refining Plant consists of the following Process Steps
Soybean 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.
Neutralization
The crude Soya Oil is first neutralised by treating alkali with crude oil. Following which centrifugal separators are used to separate soap from oil and then hot water is used to wash the soap separated oil to remove the soap stresses from the oil. Finally drying process is implied to remove moisture from the oil.
Continuous Bleaching
After the neutralization of the crude oil, the neutralised oil is bleached using Spectec’s Double Deck Bleaching System . Here the De- Gummed oil is pumped to the bleacher and the part of the oil is passed to the slurry tank and then the oil is cooled before passing it to the slurry mixture. In the slurry mixture bleaching earth is added and the same is then 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 followed by again filtration of oil by Polishing Filters. The filtered oil is then cooled.
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.
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.
Benefits of 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.
Vapour 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. Vapour are condensed, cooled, and then recalculated to condensed fresh vapour. 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.
Spectec has supplied Soya oil Refinery plant globally, and the same is recognized for its high productivity, efficiency, and cheaper operational cost of production and quality output.
