How can ZEBREX™ help you?
What is ZEBREX™?
ZEBREX™ is a cutting-edge zeolite membrane dehydration process.ZEBREX™ is proven at over 70 plants outside of the US.
1.ZEBREX™ increases production capacity.
■ZEBREX™ increases production capacity by 10-20% if there is enough fermentation capacity.■A PSA process has a REGEN stream that recycles around 20% of production back to the distillation column. ■ZEBREX™ doesn’ t have REGEN recycle stream line, so it can increase production capacity.
3.ZEBREX™ is easy to install and start up.■ZEBREX™ units are mounted on a skid for easy field installation.■ZEBREX™ process eliminates energy intensive pre-drying operation associated with the PSA process.
2.ZEBREX™ reduces energy cost.■ZEBREX™ reduces overall operation cost compared to a conventional PSA process.■Saves significant steam consumption and uses little additional electricity.
Water is separated into the tube by passingthrough the zeolite membrane
[ Ex. Water/Ethanol separation ]
Separation by Membrane
Ethanol and water are separated by the sharp selectivity of the zeolite, to produce 99.5% purity ethanol and recycle water in a single pass.
