Over the years, it has provided domestic customers with high-quality ethanol production equipment. Let's briefly talk about the ethanol production process. Welcome manufacturers with related needs to contact us to discuss business! Contact: Manager Qiu 18914371465

1. Raw materials

The industry generally uses starch fermentation method or ethylene direct hydration method to produce ethanol. The production of ethanol by fermentation was developed on the basis of winemaking. For a long historical period, it was the only industrial method to produce ethanol. The raw materials of the fermentation method mainly include grain raw materials (wheat, corn, sorghum, rice, millet, oats, etc.), potato raw materials (cassava, sweet potato, potato, etc.), sugar raw materials (beet, sugar cane, waste molasses, sisal, etc.) And cellulose raw materials (wood chips, straw, etc.).

Second, the technological process

1. Grain raw materials

2. Potato raw materials

3. Sugar raw materials

4. Cellulose raw materials

5. Synthesis method

The direct hydration of ethylene is the direct reaction of ethylene with water under the conditions of heating, pressure and the presence of a catalyst to produce ethanol:

CH2═CH2 + H─OH→C2H5OH (The reaction is carried out in two steps. The first step is to generate organic mercury compounds in water-tetrahydrofuran solution with mercury salts such as mercury acetate, and then reduce them with sodium borohydride). -Ethylene can be obtained from petroleum cracked gas in large quantities, with low cost and large output, which can save a lot of food, so it develops rapidly.

can also be converted into synthesis gas through coal chemical industry, directly synthesized or through acetic acid hydrogenation to produce industrial ethanol.

3. Quality standards

According to customer needs, the ethanol production device can meet relevant standards (GB10343-2008 special grade, superior grade, general grade, GB18350-2013, GB678-2008) or other international standards.

Four, remarks

The company can undertake a full set of turnkey projects such as alcohol, chemical, pharmaceutical, DDGS, etc.

"Saf" brand distillation and supporting equipment have a market share of more than 40% in the domestic market, ranking top three in the same industry in the country for many consecutive years.
