Rectification units for premium alcohol quality<\/h2>\n

Rectification is used in alcohol production for the purification of raw alcohol obtained from mash distillation.<\/p>\n

With a carefully considered selection of process parameter it plays the key role in tailoring the alcohol quality as required for neutral and extra neutral alcohol (ENA).<\/p>\n\n

Quality standards<\/strong><\/p>\n

We have the technology and experience to design rectification units for a wide range of applications and product specifications including<\/p>\n

    \n
  • Chemical composition of all fractions,<\/li>\n
  • Permanganate clearing time, and<\/li>\n
  • Organoleptic characteristics<\/li>\n<\/ul>\n

    Our plants are individually tailored to comply with pharmacopoeia or producer specifications and with national and international ethyl alcohol standards such as EN, GOST, JAAS and many others.<\/p>\n\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n \n

    Measures for high quality alcohol production<\/strong><\/p>\n

    For superior product quality, our process schemes are optimized for separation of impurities and avoidance of undesired chemical reactions.<\/p>\n

    Starting out from a mild distillation in a vacuum mash column, undesired substances such as aldehydes and esters are removed in the heads column. The alcohol is further concentrated in the rectification column and fractions like propanol and higher alcohols are stripped off. In the repurification column methanol is removed.<\/p>\n\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n \n

    Comprehensive approach<\/strong><\/p>\n

    We look at every aspect of plant performance: quality, yield, costs. Specific design features include<\/p>\n

      \n
    • Fully continuous operation<\/li>\n
    • Distillation in vacuum<\/li>\n
    • Low scaling tendency<\/li>\n
    • Use of latent heat for thermal integration<\/li>\n
    • Pre-heating of mash with raw alcohol vapors (= no loss of heat in evaporation)<\/li>\n
    • Highly efficient column tray and internal designs<\/li>\n<\/ul>\n\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n \n

      Supply of rectification equipment<\/strong><\/p>\n

      In addition to our engineering services we supply equipment ranging from trays – as a process-critical component – to complete rectification facilities set up on EPC basis.<\/p>\n\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n","protected":false},"excerpt":{"rendered":"
