APPLICATIONS

SEPARATION OF AZEOTROPIC MIXTURES IN CHEMICAL PROCESS INDUSTRIES

Many commonly used solvents form azeotropes with water and distillation alone cannot separate them. AZEO-SEP™ (Pervaporation) membrane selectivity is not affected by azeotope formation.

INCREASING DISTILLATION COLUMN EFFICIENCY FOR LOW VOLATILITY FEED

Distillation columns operating with low volatility differences of the feed components require a high reflux ratio. AZEO-SEP™ (Pervaporation) fluid separation is independent of volatility differences. A hybrid AZEO-SEP™ (Pervaporation) unit attached to a distillation column will increase throughput and reduce operating costs.

SOLVENT RECOVERY IN PHARMACEUTICAL AND CHEMICAL INDUSTRIES

In-house recovery of spent solvent is a difficult process for distillation as the solvents used form azeotropes with water. AZEO-SEP™ (Pervaporation) units minimize the disposal of used solvents and fresh solvent cost.

INCREASING REACTION YIELD

In some chemical reactions, the product yield is limited by the formation of water. Continuous water removal from an equilibrium controlled reaction mixture by an AZEO-SEP™ (Pervaporation) distillation hybrid unit will improve the reaction yield. An example is the process of formation of esters from acids and alcohols.

DEHYDRATION OF SOLVENTS RECOVERED FROM ACTIVATED CARBON BEDS

Solvent vapors in effluent air from various industrial drying processes are often captured in activated carbon beds. These solvents are subsequently desorbed using steam. The recovered solvents with high water content can be dehydrated using AZEO-SEP™ (Pervaporation).
