Pervaporation pilot

Pervaporation pilot

The Convergence Inspector Pervaporation pilot was developed to perform permeability studies at different temperatures and pressures. The term pervaporation is derived from the two steps of the process: 1) permeation of the permeate through the membrane and 2) its evaporation at the permeate side.

Specifications

Feed flow range: up to 325 L/h
Feed flow accuracy: < 2 %
Pressure range: 0,5 – 6,9 barg
Pressure accuracy: < 0,1 %
Temp. range feed: 0 – 100°C (higher temperatures optional)
Dimensions: 60 x 50 x 93 cm

Pervaporation pilot

The Convergence Inspector Pervaporation pilot was developed to perform permeability studies at different temperatures and pressures. The term pervaporation is derived from the two steps of the process: 1) permeation of the permeate through the membrane and 2) its evaporation at the permeate side.

The unit includes a circulating feed and a permeate line. On the permeate a vacuum is applied to increase the driving force of the process. An in-line heat exchanger then condenses the permeate. The pervaporation setup allows the separation of two or more components that are difficult to separate using common thermal separation processes like distillation. It is commonly used for dewatering of hot organic solvent streams.

The user-friendly software interface records flows, temperatures and pressures and allows the creation of individual test scripts. A permeate side balance allows automatic calculation of permeability. The system allows you to attach all kinds membrane modules and thus makes it extremely flexible.

-In-line pH measurement
-Customized flow- and pressure range (higher or lower)
-Upgrade to chemical resistant Hastelloy/Duplex components
-Heating and cooling baths
-Peltier cooler
-N2 cold trap
-Permeate side flowmeter
