EcoMol - Molecular Sieve Dehydration Plants
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.
