SOLUTION: For dehydration of rectified ethyl alcohol the
process provides using of propyleneglycol as dehydration agent,
which having been introduced into hydroalcoholic mixture
(rectified ethyl alcohol hydroalcoholic waste), form triple
mixtures: ethyl alcohol - water - propyleneglycol. At distillation
of these mixtures water remains linked to propyleneglycol and
ethyl alcohol is dehydrated to the ethanol concentration of 98.9 -
99.5% by volume. Used propyleneglycol is collected,
Description regenerated and returned into dehydration process.
ADVANTAGES: Propyleneglycol is not toxic, at dehydration
does not pass into ethyl alcohol and easily regenerates, is stable
and does not change during dehydration of ethyl alcohol or its
regeneration. Dehydration installations, using propyleneglycol as
dehydration agent, may be installed in locations directly at
factories producing ethyl alcohol.
STAGE: At present, at company "Comvincom", or. Comrat,
Republic of Moldova, it is designing an installation producing
bioethanol using propyleneglycol as a dehydration agent.
