I. Raw materialsIn industry, ethanol is generally produced by starch fermentation or ethylene direct hydration. Ethanol by fermentation was developed on the basis of wine making. The raw materials of fermentation mainly include grain raw materials (wheat, corn, sorghum, rice, millet, oats, etc.), po

A new technique for treatment of furfural wastewater by closed circuit evaporation and recyclingI, our company has a patentII. OverviewFurfural production wastewater is a difficult organic wastewater, containing acetic acid, furfural, alcohol, aldehyde, ketone, ester, organic acid and other organic

Threonine continuous crystallization techniqueI. OverviewThreonine filter liquid produces crystals when it evaporates at low concentration. In order to save power consumption and avoid crystal precipitation, four-effect evaporation mode combining "rising film and falling film" is adopted to realize
