Transesterification Method Biodiesel Project

bio-diesel project to the fatty acid mono-alkyl esters getting from animal fats and plant oil(glycerin three esters of fatty acids) and alcohol(methanol or ethanol), through ester exchange reaction, and fatty acid methyl ester is the most typical.

Product Description

Bio-diesel is extracted from animal fats,plant oil, and widely used for trucks, tractors, ships, etc. It refers to use oil crops, such as soybean, rapeseed, cotton, palm, wild oil plant and engineering micro algae and other aquatic plant oils and animal fats, food waste oil as raw oil material, through ester exchange process , producing a kind of reactivity diesel fuel which could instead of petroleum diesel. 

We company use discharge method without acid to produce biodiesel.

The whole process is closed-circuit circulation, all raw material comprehensive utilization, cleaner production. Roughly described as follows:
Raw material pretreatment (dehydration, deodorization, purification )-----the reaction kettle (methyl ester+ alcohol catalyst + 70℃) -----stirring reaction N hours----precipitation separation line of mixed alcohol----methyl distillation----recovery of alcohol----methyl ester distillation----finished product.

 

(1) Physical degumming: first of all, using oil hydration or phosphoric acid-etching method, remove the phospholipids and colloid and other substances, and then preheating, dehydration the oil.

(2)Methanol esterification: adding excess methanol into the raw oil material, with the acid catalyst, conduct pre-esterification, changing free acid into methyl ester.

(3)Continuous ester exchange:  the pre-esterification oil together with methyl alcohol, adding little NaOH as catalyst, under a certain temperature and atmospheric pressure, conduct ester exchange, then get methyl ester.
  Using two-step reaction, through a specially designed separator continuously eliminate the glycerin engendered in the reaction, make the ester exchange continuously.
(4)Gravity precipitation, water washing and stratification.
(5)Glycerol separated from crude methyl ester.
(6)Bio-diesel refined.

We could not find any corresponding parameters, please add them to the properties table
