waste oil biodiesel production process and distillation column diesel gasoline

What is biodiesel?

Biodiesel is a renewable, clean-burning diesel replacement that is reducing our dependence on foreign petroleum, creating jobs and improving the environment.
The EPA has recognized biodiesel’s environmental benefits by classifying it as an Advanced Biofuel, making biodiesel the only commercial-scale fuel produced nationwide to meet the agency’s advanced criteria.

What are the raw materials of biodiesel?

Pretreatment

There are many moisture, impurity in the raw material, so before esterification must first to make roughly filter, fine filter and falling film drying treatment, in order to get the standard oil.

Esterification Reaction

According to a certain proportion and velocity put standard raw oil, glycerol and catalyst into esterification reaction tower, open heating device by adjusting to the requirements of the technical parameters, during the reaction process, water removed promptly from the system. After sampling and testing, can be continuous discharge. The main free fatty acid and glycerol are the main free fatty acids and glycerol to produce triglyceride and water, while a small amount of single and two.

Trans Esterification

The responses of ester exchange reaction occurs mainly by the reaction of triglyceride and methanol, in the reaction process mainly generated methyl ester and glycerol, and part of the monoglycerides, diglycerides are generated.

Biodiesel Distillation

the biodiesel distillation unit is a multi - type self - diversion and vacuum distillation unit, and the distillation system is heated by heat conduction oil.The utility model has the advantages in distillation, distillation, separation system as a whole, reducing the biodiesel residence time in the equipment, to ensure that the color of the biodiesel, cold material first and finished heat and heating into a distillation tower, give full consideration to the secondary utilization of heat energy, saving the production cost.

Glycerin Refining

Due to the ester exchange containing methanol and little soap, recycling must be done before the alcohol treatment to avoid loss of methanol. The first glycerol ester exchange settlement after the discharge of introducing glass lined reactor regulation in a neutral or weak acidic, backward in glycerin settlement the desalting tank, then into the distillation tower of dewatering of purified alcohols. 

Methanol Recovery

Excess methanol in the system will go to distillated in the methanol distillation tower and then be recycling used.

1.What is the warranty of the machines?
12 months free guarantee and life long standard paid service.
2.What is the raw material of your machinery?
Stainless steel and carbon steel.
3.When can I get the price?
Within 24 hours, if urgent, please directly contact us.
4.How to ask quotation?
Please inform us you oil seeds and your target capacity per day, then we will send our advices with equipment list to you at once.
5.Can we ask the oil plant for different types of oil?
Yes you can! But we recommend no more than 3 kinds of oils.
6.Why should we add solvent extracting line?
Oil residue rate in pressed cakes will be about 6% if only applying physical pressing. Then solvent extraction will be applied to extract the pre-treated oil seed to short the 6% oil residual to less than 1% to increase the oil output.
7.How many areas are required to build my plant?
The land area required usually depends on the capacity of your plant. We can calculate the area needed and give you the plant designs.
8.How long will it take to get my products?
In general, it will take us 10-70 days to make the machinery, and 3-7 days to shipping port.
9.Can you install the production line and train our stuffs for free?
Yes we can. We'll send professional installation engineers to help you install the equipment and train your workers freely.
