Meniscus Membranes for Separations
Abstract
Gas separation membranes, especially meniscus-shaped membranes for gas separations are disclosed together with the use of such meniscus-shaped membranes for applications such as thermal gas valves, pre-concentration of a gas stream, and selective pre-screening of a gas stream. In addition, a rapid screening system for simultaneously screening polymer materials for effectiveness in gas separation is provided.
Application(s)
- Carbon dioxide (CO2) separation
- Pre-screening element for contaminants
- Pressure/temperature sensor element
- Pre-concentrator for mass spectrometer
- Rapid membrane efficacy screening for polymers
- Use as a temperature-controlled valve in gas separations
Advantages
- Higher temperature operation than previous polymer membranes
- Higher pressure operation than previous polymer membranes
- Faster, cheaper screening of polymers for use as separation membranes
- Simple, low-cost temperature-controlled valve
- Effective pre-screen and pre-concentrator for sensors
