Product oil

the deacidification is very important for vegetable oil refining.

it usally is chemical way or physical way.

Comparison :

chemical way deacidification:

Add in a certain concentration of NAOH which will neutralize the FFA. The FFA will subside in the way of soapstock. some impurities will also centrifugal separated with the soapstock. The advantage of chemical way is deacidification thoroughly and the quality of the oil is stable. The disadvantage is oil loss. The FFA content is higher; the oil loss is bigger.

Physical deacidification:

it is in the vacuum condition, let the steam bring out FFA,unsaponifiables, odorants. In this process, No soapstaock produced, and the quality of FFA is high, some heat sensitive pigment like carotene and odorants will be removed too. The operation is easy and the quantity is large. Also the oil loss is small and noenvironmentalpollution. Compared to the chemical way, it has its disadvantages too, for physical way refining, the pretreatment of the crude oil is strict, it is not suitable for cotton seed oil which is heat sensitive. And in the high temperature, the oil will produce polymer. The physical way refining is only suitable for good quality crude oil deacidification and it requires strict pretreatment sometimes even decoloration of the crude oil.

Process of deacidification:

1. Neutralization:

In neutralization which means deacidification process, the oil at a proper temperature is added in proper concertration of lye, goes into centrifugal mixer. For best mixing, the mixture is sent into neutralization tank and stay for enough time. During this period, the lye will neutralize the FFA, form soapstock and are separated in neutralization separator. The formed soap stock also can absorb other impurities and pigments. To separate the oil and soapstock more easily, the mixture would be heated, to reduce the viscosity.

2.Washing:

The neutralized oil from the neutralization separator, still contain about 500ppm soap. to reduce the soap content, the oil would be added into about 15% hot water and to wash in the washing mixer. The hot water will absorb the soap and other impurities, then are separated in the washing separator

3.Vacuum-drying and dewatering

The oil from the washing separator still contains some water which is harm to oil stability. To remove this part water, the oil at a temperature of 110-120”C, are sent into Vacuum drying tower to dry the water. After this the oil will be pumped into decoloration process.

Process of decoloration

decoloration aims to remove the pigment and The residual soap etc. it includes:

1.decoloration

The oil firstly should be heated to 105”C.The heated oil then is sent to Vacuum bleaching tower. when the oil goes into the bleaching tower, it mixed with white clay via ratio mixer.

White clay transportation system is used to send the white clay on the ground to the storage tank on the top of bleaching tower.

The bleaching tower are divided into several floors, every floor is equipped with steam ejector which used to mix the oil and white clay. The rest soap, gum, pigment and other metal would be absorbed by the white clay too.

2.filtration

the mixed oil from bleaching tower would be pumped into the filter, and then goes into the secondary filter, here white clay and the solid impurities would be stopped, the bleached oil would be transferred to bleached oil storage for middle storage.

In this filtration system, there are 2 decolorizing filters, always one in filtering and another is emptying and cleaning. When the filter are in emptying and cleaning condition, the filter would be squeezed by steam, so most oil in the filter would be swept into bleaching oil tank, few oil mixed with waste white clay is sent into dirty oil tank. The filter cake have been dried by steam, the leftover oil and water gathered during the drying period are sent into the dirty oil tank too. Finally the dried cake on the bottom of the filter was poured into waste clay room via bleed valve by air vibrator.

The leftover oil in the dirty oil tank would be pumped into bleaching tower for reworking.

Deodorization section

The deodorizing aims to remove the FFA,small molecular substances,including

1.Gassing

The bleached oil are stored in bleached oil tank, this tank are designed to work in vacuum condition. From this tank, the bleached oil is pumped into deaerator, to release the gas into the oil.

2.Heating

The flow of the bleached oil is controlled by a controller, the oil is heated at a temperature of 250-260”c by a series of heat exchanger.

When the oil is heating in the final oil heater, here some low- boilling point FFA and volatiles would evaporate. The steam and liquid oil would go into the packing deodorizing tower from different entrances.

3Deodorization

The heated oil would be distilled in the flashing tower, storage tank and main deodorizing tower, the FFA and smell matters would be removed aftergasification

we are Doing Machinery in China. We have been specialized in edible oil making and bio-diesel production line for over 40 years. We provide turn-key service including machines, installation, person training, after sales and tech consulting.

Other products:

Advantagess of bio diesel:

1.Can work succesfully under low temperature, can be at -10”c without additive.

2.Good lubricating performance, less damage to Engine

3.Flash point higher more safer in storage, transportation, and usage.

4. reduce 30% sulfide emissions, even 70% when with catalyst.
5. less small particulates in the waste gas.

6 No aromatic compounds in bio diesel.

7 Reduce the CO2 emissions

8 the price could be stable and big reduction too.

9. not controlled by OPEC benefit the international oil market

In many countries, there are favorable policies to support bio diesel production. It is predictable high economic value invest.if you are interested in our machine,please feel free to contact me.
