ZEBREX contributes to the optimization (efficiency improvement) of your plant. Not only is ZEBREX an energysaving dehydration process by itself, it also makes it possible for us to offer optimization proposal for process as
an integrated system with Distillation to maximize its efficiency. As a dehydration process, ZEBREX can be applied
to bioethanol plants that use all sorts of raw materials.

Zeolite membrane dehydration technology● Capacity expansion◦Policy to increase the ratio of bioethanol in fuele.g. E10 → E15.

SUCCESS● Energy saving◦Enhanced energy saving regulations.
◦Policy to grant a premium to bioethanol producedwith lower energy.

● Increases dehydration capacity.

ZEBREX can be customized according to the situation, purpose and budget of your plant. Even just “Add-on”
to your existing plant can achieve both energy saving and increasing capacity. With “Exclusive” or “Replace”,
amount of energy saving gets more, and it is also expected to reduce the maintenance cost of mole sieves / PSA.
Furthermore, in the case of “Green Field”, a new plant construction, the energy saving can be maximized byoptimizing the process design of ZEBREX and Distillation as an integrated dehydration system ZEBREX has a trackrecord of more than 70 installations around the world.

Optimization of the distillation column andZEBREX to achieve maximum efficiency.
(Distillation column size will be smaller thanusual, because ZEBREX can accept lower
ethanol concentration for the feed fromDistillation, and dehydrate it efficiently.)

The core material / technology of ZEBREX is zeolite membrane. Water and ethanol are separated by zeolite
membrane that has homogeneous pores. This dehydrating process is efficient because it is continuous and startup / shut-down is also quick. The plot plan of the ZEBREX dehydration UNIT can be arranged according to yourcircumstances.
