EcoMol Molecular Sieve Dehydration Plants |
As the demand for fuel ethanol grows, technology for production of fuel ethanol becomes critical. Some of the key considerations while selecting the right technology would be:
How futuristic is the technology so and you will not be required to upgrade it constantly?
How does it build upon your current facilities so that your investment in fuel ethanol plant is minimal?
Does it take care of your energy bill? Can the technology handle a wide spectrum of raw materials?
Is the technology robust? Is it truly a clean technology, with no presence of entrainers like cyclohexane?

Why is it a better Technology? Fast de-pressurization of bed during regeneration may cause the bed to fluidize, crushing the molecular sieve beads. The MolSieve bed offered by Praj is designed for gentle movement, thus ensuring longer desiccant life. Depending on the requirement, Praj can supply skid mounted units for smaller capacities which are easy to install.
There are two modules available for recovering the alcohol in the regeneration stream.

Offering you comfort from all the above factors.
Conventionally, azeotropic distillation has been employed in production of Fuel-Ethanol. In azeotropic distillation, dehydration is carried out in presence of entrainer like benzene or cyclohexane. Although benzene has been banned in several countries for its carcinogenic effect, cyclohexane is still being employed. The distillation method is very energy intensive. A large number of plants in Brazil still run on this technology.
The EcoMol Pressure Swing Absorption technology offers the following advantages:
- Constant product quality
- Lowest Energy Consumption
- Maximum Alcohol Recovery
- High turndown ratio
- Automation and Control system
- Longer & Life of desiccant
- Low presser steam model for single mill attached plant.
