Rectification is used in alcohol production for the purification of raw alcohol obtained from mash distillation.
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).
We have the technology and experience to design rectification units for a wide range of applications and product specifications including
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.
For superior product quality, our process schemes are optimized for separation of impurities and avoidance of undesired chemical reactions.
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.
We look at every aspect of plant performance: quality, yield, costs. Specific design features include
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.
