Small Scale Palm Oil Refinery Plant Fully Physical Refining
Main equipment:
Degumming tank, Heat Exchanger, Decolorizer, filter, Deodorizer, etc.
Technique Description:
Physical refining refers to the refining method that instead of the alkali neutralization reaction, free fatty acid in crude oil is removed by vacuum water steam distillation to achieve the purpose of deacidification. Physical refining is especially suitable for the refining of low gum and high acidity fats.
Advantages:
Process Description:
The newly completed continuous bleaching section uses two alternate filters. The mixing oil and earth flow into the Vacuum bleaching tower. The bleached oil is pumped through the alternate filters. The valves are automatic switched. Filtered oil is pumped into deodorization section after safety filters.
The reaction mechanism of nano-neutralisation technology is to use a high pressure pump to transport the degummed grease (or gross oil) and lye into the nano-reactor, where the lye and grease react. When the fluid passes through the nano-reactor under high pressure conditions, the mixture of grease and lye forms a high speed turbulence inside the nano-reactor, generating a very high shear force and destroying the molecular groups in it, enabling a fast and efficient completion of the Acid-base reaction.
After heating with deodorized oil, the un-deodorized oil is pumped into vacuum heat exchanger to be heated with conduction oil boiler before deodorization system. Before deodorizer, the heated oil needs to pass through sieve-plate columns special designed to remove large amount of fatty acid. Right here, the fatty acid amount to absolutely low. Some odour material needs a longer time to be removed, but will be finally removed or inactive in column-plates. The oil reserved in the column-plates has been sprayed a ratio of mixing steam.
