| titleOfInvention | Novel method for preparing vinyl acetate from bioethanol |
| abstract | The invention relates to a novel method for preparing vinyl acetate from bioethanol. Ethanol is fermented into finished yeast mash used as the raw material, and three cells, i.e. bio-ethylene preparation, vinyl acetate synthetic reaction, vinyl acetate refinement, are used for producing the vinyl acetate product satisfying the requirements. The method is realized in a way that: the mass concentration of the ethanol water solution from an ethanol distillation tower is 40-60%, and the raw material ethanol used for preparing ethylene through dehydration does not need to be diluted by adding water, and is directly vaporized by heating and conveyed into an ethylene reactor; after cooling to condense the ethylene reaction gas from an ethylene reactor, gas is separated from liquid in a gas/liquid separating tank, and the gas mainly containing the ethylene is conveyed to a vinyl acetate reaction unit to synthesize the vinyl acetate after being compressed by using an ethylene compressor, thereby realizing zero consumption of process water in the ethylene production process. Thus, the invention simplifies and shortens the production process and reduces the energy consumption and material consumption in the vinyl acetate production process. By using the method, renewable biomass materials in the vinyl acetate production process can partially replace unrenewable fossil materials. |
