Vegetable Oil Refineries and Fractionation
Systems for Multi-Oil Processing
Our vegetable oil refineries and fractionation systems are exclusively designed to carry out and successfully process several oils like sunflower, rice bran, mustard, soya, cottonseed, palm, palm kernel, and corn oil. The refining process includes a series of meticulously designed stages. Our full-fledged process differs based on the type of oil and the designated refining method, decisive of whether chemical or physical.
01
Degumming Section
Acid Dosing System
Accurately doses phosphoric or citric acid into crude oil for hydration of gums and better separation efficiency.
Mixing Vessel / Conditioner
Specially designed tank with agitator to ensure uniform mixing of oil with acid/water under controlled conditions.
High-Speed Separator (Centrifuge)
A disc-type centrifuge that separates hydrated gums, phospholipids, and other impurities from crude oil with high efficiency.
02
Neutralization Section
Neutralizer Vessel / Reactor
Provides controlled mixing of oil with caustic soda solution to neutralize free fatty acids.
Mixer-Settler
Ensures proper contact between alkali and oil; soap stock settles at the bottom for easy removal.
Neutralizing Separator (Centrifuge)
Rapid separation of soap stock and wash water from oil, ensuring minimum oil losses.
03
Bleaching Section
Bleaching Reactor
A vacuum-operated vessel where oil is mixed with bleaching earth/activated carbon. Provides uniform adsorption of color pigments, soaps, and peroxides.
Bleaching Earth Dosing System
Pneumatic or screw feeder system ensures accurate and dust-free dosing of bleaching earth into the reactor.
Pressure Leaf Filter / Hermetic Filter
Removes spent bleaching earth and impurities to deliver clear, clean oil for further processing.
04
Dewaxing / Winterization Section (for waxy oils like Sunflower, Rice Bran, Corn, etc.)
Crystallizer / Cooling Vessel
Oil is chilled under controlled conditions to crystallize waxes. Maintains precise cooling curves for maximum separation.
Chilling Plant / Plate Heat Exchanger
Provides uniform and energy-efficient cooling of oil for crystallization.
Filter Press / Membrane Filter
Separates crystallized waxes from oil, ensuring crystal-clear winterized oil.
05
Deodorization Section
Deodorizer Tower (Packed / Tray Type)
A stainless-steel column where oil is treated with high-temperature steam under vacuum to remove odor, flavor, and FFA.
Stripping Steam Generator
Produces clean, dry steam for stripping volatile impurities during deodorization.
Heat Recovery System (Economizer)
Recovers heat from deodorized oil to preheat incoming oil, ensuring energy savings.
Vacuum System
Multi-stage steam ejectors or vacuum pumps maintain deep vacuum during deodorization for efficient removal of volatiles.
06
Fractionation Section (for Palm Oil and Specialty Fats)
Crystallizer / Cooling System
Cools palm oil under controlled conditions to form crystals of stearin (solid fraction).
Membrane Filter Press
Separates liquid olein and solid stearin fractions with high efficiency.
Neutralizing Separator (Centrifuge)
Rapid separation of soap stock and wash water from oil, ensuring minimum oil losses.
Supporting Systems in Edible Oil Refinery
Steam Boiler System
Supplies steam required for heating, stripping, and deodorization in the
refinery
Boilers generate saturated steam at controlled pressure and temperature, which is used in oil heating exchangers, stripping steam for deodorization, and other process applications. A well-designed boiler system ensures stable steam supply with high fuel efficiency.
Features
High-pressure and high-efficiency steam generation
Equipped with economizers, blowdown systems, and auto controls
Can operate on coal, oil, gas, or biomass fuels
Essential for consistent plant performance
Cooling Tower System
Provides cooling water for condensers, heat exchangers, crystallizers, and other
refinery utilities
Cooling towers reject process heat into the atmosphere by cooling the circulating water. This ensures optimal operation of vacuum condensers, plate heat exchangers, and chilling plants. Proper cooling is essential for maintaining vacuum in deodorization and dewaxing.
Features
Induced draft counterflow or crossflow design
Equipped with drift eliminators, distribution nozzles, and fans
Ensures energy-efficient water circulation
Air Compressor & Instrument Air System
Supplies compressed air for pneumatic valves, instruments, and automation systems
Air compressors generate clean, dry compressed air that powers refinery automation, filters, dosing systems, and safety controls. Drying units ensure moisture-free air for reliable instrumentation.
Features
Screw compressors with storage tanks
Air dryers and filters for moisture and oil-free supply
Stable pressure output for consistent operation
Water Treatment Plant (WTP)
Provides treated water for boiler feed, process steam, and cooling systems
Since untreated water can cause scaling, corrosion, and contamination, a dedicated WTP ensures supply of demineralized (DM) or softened water. This extends equipment life and ensures high-quality steam generation
Features
Filtration, softening, reverse osmosis (RO), and demineralization units
Automatic regeneration and backwashing systems
Ensures reliable supply of high-purity water
Effluent Treatment Plant (ETP)
Treats wastewater generated from neutralization, washing, and utility operations before safe discharge
The ETP removes oil, grease, alkali, and suspended solids from wastewater, ensuring compliance with environmental standards. Sludge is separated and treated for safe disposal
Features
Primary oil-water separators
Biological treatment units (aeration, bio-reactors)
Sludge drying beds or filter presses
Zero liquid discharge (ZLD) option available
Spent Bleaching Earth Handling System
Safely handles and disposes of spent earth from the bleaching section
A pneumatic conveying or screw conveyor system transfers spent earth from filters to storage silos. This prevents spillage, reduces fire hazard, and allows recovery of entrapped oil
Features
Closed conveying system for dust-free handling
Fire-safe storage silos with nitrogen blanketing (optional)
Oil recovery units for minimizing losses
Oil Storage & Transfer System
Stores crude and refined oil safely and ensures smooth transfer between process sections
Storage tanks are designed with heating coils, insulation, and nitrogen blanketing to preserve oil quality. Transfer is carried out using food-grade pumps and pipelines
Features
Vertical and horizontal tank designs
Stainless steel or mild steel with epoxy coating
Positive displacement or centrifugal pumps
Automatic level control and monitoring systems
