Introduction to Biodiesel Equipment Project

The biodiesel project of Jiangsu Yuanhe Energy Technology Co., Ltd. is a key development project of the Chinese Academy of Sciences Guangzhou Energy Research Institute. Jiangsu Yuanhe Energy Technology Co., Ltd. is one of the large-scale enterprises in China engaged in the production, equipment, technology, marketing, research and development of biodiesel (organic refining) through organic refining projects such as waste animal and vegetable oil (gutter oil) refining, straw refining, and catering waste refining.

Biodiesel equipmentProduction process:

(1) Physical refining: Firstly, the oil is hydrated or treated with phosphoric acid to remove substances such as phospholipids and colloids. Preheat, dehydrate, and degas the oil into the deacidification tower to maintain residual pressure,

Excess steam is introduced, and at the steam temperature, free acids and steam are evaporated together. After condensation and precipitation, the net loss except for free fatty acids can be reduced to extremely low levels in oils and fats

Quantity and pigments can also be decomposed, making the color lighter. Various waste animal and vegetable oils are synthesized into crude fatty acid methyl esters through a simultaneous esterification and alcoholysis process using a self-developed DYD catalyst.

(2) Methanol pre esterification: Firstly, the oil is hydrolyzed and degummed, and then the flocculent substances formed during hydration such as phospholipids and gums are removed using a centrifuge. Finally, the oil is dehydrated. Excessive addition of methanol to raw oil and fat

In the presence of an acidic catalyst, pre esterification is carried out to convert free acid into methyl ester. Steam out methanol water, and after distillation, separate C12-16 palmitic acid methyl ester and C18 oleic acid methyl ester without free acid.

(3) Ester exchange reaction: Pre treated fats and oils are reacted with methanol, and a small amount of NaOH is added as a catalyst. The ester exchange reaction can be carried out at a certain temperature and atmospheric pressure to generate methyl ester. A two-step reaction is adopted, and glycerol generated in the initial reaction is continuously removed through a specially designed separator to continue the ester exchange reaction.

(4) Gravity precipitation, water washing, and stratification.

(5) Separation of glycerol and acquisition of crude methyl ester.

(6) Dehydration, methanol release, catalyst release, and refined biodiesel production

application area

Biodiesel can be used as fuel for boilers, turbines, diesel engines, etc. The main industrial application is fatty acid methyl esters. Biodiesel is a high-quality and clean diesel that can be extracted from various biomass sources, making it an inexhaustible energy source. In today's increasingly depleted resources, it is expected to replace petroleum as an alternative fuel.
