ZEBREX
ZEBREX™ is a cutting-edge zeolite membrane dehydration process. With a proven track-record at over 70 plants in the world, the combination of dehydration devices with ZEBREX™ zeolite membranes for bioethanol manufacturing processes can contribute to energy-saving and increased production. It is also best suited for processes for collecting and dehydrating solvents such as NMP (N-Methyl -2-Pyrrolidone), isopropanol, and ethanol.

Characteristics

ZEBREX™ (zeolite membrane dehydration process) increases production capacity.

The ZEBREX™ dehydration system is expected to increase production capacity by 15–25% compared to the PSA process (pressure swing adsorption method, which is frequently used at existing bioethanol plants).

ZEBREX™ (zeolite membrane dehydration process) reduces energy cost.

  • ZEBREX™ reduces overall operation cost compared to a conventional PSA process.
  • The ZEBREX™ dehydration system does not require the regeneration because it is able to continuously separate water and ethanol, while the conventional PSA process uses considerable energy. For this reason it is able to reduce steam consumption (utility costs) significantly compared to the PSA process.

ZEBREX™ (zeolite membrane dehydration process) 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.
