High Technology Automatic Rapeseed Oil Refining and Dewaxing Plant
Product Discription
Why is Vegetable Oil Refined?
Vegetable and Animal Oils and Fats have impurities such as Moisture, Solids (Insolubles), Gums (Lecithins), Free-Fatty Acids (FFA), Waxes, and Compounds of Sodium, Potassium, Magnesium, Calcium, and other metals.
These impurities must be removed to improve the functionality of the oils. Other characteristics of oils (such as Color, odor, and taste) are also considered impurities by modern consumers.
These impurities are removed in a series of steps such as degumming (to remove gums), neutralizing (to remove FFA), bleaching (to remove color), deodorizing (to remove odor and taste), and dewaxing or winterization (to remove waxes).
Main process of crude oil refinery plant
--- Neutralization section
Crude oil from tank area is sent to crude oil tank in the workshop by pump, after accurate measurement with mass flow meter enters crude filter,
remove bigger mechanical impurities in the crude oil.After the filtered oil and deodorizing oil are fully exchanged in the plate heat exchanger, heated
by crude oil heater and mixed with phosphoric acid whose concentration is 85% in oil acid mixer, the addition quantity of phosphoric acid is added
at a certain quantity with metering pump according to processing capacity and crude oil quality. After mixing of oil and acid, enter acidification reaction
tank to reduce the content of nonhydratable phospholipid,then enter oil alkali multi-effect mixer, after good mixing of oil and lye at certain concentration
pumped by metering pump, enter neutralization tank, utilize liquid level automatic control in neutralization tank to adjust the reaction time, oil after reacting
in reaction tank is pumped into plate heat exchanger is heated to about 90ºC, and enters centrifuge to remove soap-stock; alkali refining adopts middle
temperature reaction, high temperature separation, not only reduce saponification of neutral oil, but also improve separation effect of centrifuge and
refining yield; the oil after removing soap-stock with first centrifuge enters oil water multi-effect mixer, which adopts frequency conversion control,
to prevent excessive mixing intensity and oil-water emulsification.Oil after water washing enters the second centrifuge for centrifugal dehydration,
control dehydration temperature at about 90ºC.Dehydrated oil is heated to about 100ºC by plate type heater, and then enters vacuum dryer for drying
and dehydration, drying temperature is adjustable through automatic control, dehydrated oil enters bleaching pre-mixing tank directly, soap-stock removed
from soap-stock removal centrifuge is pumped into outdoor soap-stock temporary storage tank by soap-stock pump.Water separated by water washing
centrifuge enters combined water separation tank, separated oil is pumped into workshop crude oil tank, separated water is discharged to water seal pool
through indoor trench to recycle residual oil in water.
--- Bleaching section
Exchange heat between neutralized oil and deodorization oil, then heat to 105-115ºC by plate heat exchanger, enters premixing tank to mix
with bleaching clay( 1-3% of oil weight),then overflow into bleaching tower(bleaching temperature and time is adjustable by automatic control),
then it is pumped into two alternating horizontal filters by special oil slurry pump for filtration, filtered oil enters dewaxing section after polishing filtered.
Waste bleaching clay is discharged to waste bleaching clay room.
--Dewaxing section:
The natural oil is comprised of triglycerides mixture; due to different fatty acid carbon chain length, unsaturation degree, the composition and position
of the double bond, and the distribution of each fatty acid in the triglyceride,there are differences in physical and chemical properties. Dewaxing is
based on the difference in melting point of physical properties and its solubility, the oil is divided into solid and liquid part at a certain temperature.
Dewaxing can improve oil quality, sensory, taste, etc.
--- Deodorization section
Filtered bleaching oil enters deaerator tank directly to remove oxygen in the oil, deoxygenized oil exchange heat with deodorization oil, and heated
by heat conduction oil heater to 250ºC,then oil goes through padding part by the methods of falling film countercurrent stripping, stripping capacity is high,
splash is little, fatty acid can be removed rapidly to avoid hydrolysis happen; oil flows into board part through pipe, direct steam in board part erupt from
oil with the shape of bubble, and contact oil for stripping again, reduce boiling point of odor matters through high vacuum in the board part, and through
distillation of superheated steam to reach deodorization purpose, and delay for thermal bleaching. Deodorized oil is discharged from the bottom of
deodorization tower, this process takes about 65~80min. Deodorization oil is drawn with shield pump through oil-oil heat exchanger, bleaching oil
heat exchanger, crude oil heater respectively,and finished oil cooler to cool the oil below 40ºC,finally enters finished oil storage tank through polishing filter.
--- Vacuum auxiliary section
Drying and bleaching vacuum system adopt condenser and water circulating vacuum pump types,circulating cooling water which is cooled
by frozen water in condenser can be recycled. This system do not use steam,little power consumption, less running machines, and its convenient
for maintenance. .Deodorization vacuum system adopts combined types of steam jet vacuum pump, condenser and water circulating vacuum pump,
steam jet pump adopts 9bar steam, energy-saving, reduce steam consumption, cooling medium of deodorization vacuum system adopts 25ºC∽28ºC
cooling water, cooling water can be recycled after cooling by cooling tower.
Process technical feature:
The whole plant adopts waste heat utilization technology. In every section, set energy-saving heat exchanger, finished oil at high temperature to
do heat exchanging with bleaching oil, dry oil and crude oil in turn from high to low according to different process temperatures, which can make
maximum use of waste heat of deodorization finished oil,reduce steam consumption. All steam condensate water of heating equipment is recycled
into hot water tank for reuse. Drying of water washing oil adopts vacuum drying technology, compare with traditional technology, not only reduce
steam consumption, but also prevent oil from contacting air,reduce oil oxygenation efficiency, keep the maximum inherent nutrition value.
When blow bleaching clay,design odor trapping device, use circulating water cooling to catch odor of blowing steam, remove odor pollution
in the decolorization process, meet environmental requirement.
Set self-spraying device in waste bleaching clay room, spray cooling water when discharging cake from filter, ensure effective cooling of bleaching clay,
avoid spontaneous combustion of bleaching clay, play a role safe production.The crystallization tank adopts vertical structure internal stirring
system,with advantages of long crystallization time, large crystal particles and good dewaxing effect.
The entire workshop is fully automated, and all key control points such as temperature, pressure and liquid level are displayed on the
computer and automatically controlled.
