Tunable Composite Membranes for Gas Separations

TUNABLE COMPOSITE MEMBRANES FOR GAS SEPARATIONS Quarterly Progress Report

A New Resistance Model for Interpretation of Gas Permeation Data of Composite and Asymmetric Membranes

In this work a new resistance model has been presented based on that of Henis-Tripodi which can be used for interpretation of gas permeation data in composite and asymmetric membranes. In contrast to the previous works, in this model the fraction of the support layer surface that includes the pores filled with coating material has been taken into account. The influences of the filled pores on s...

Asymptotic Analysis of Binary Gas Mixture Separation by Nanometric Tubular Ceramic Membranes: Cocurrent and Countercurrent Flow Patterns

Analytical gas-permeation models for predicting the separation process across  membranes (exit compositions and area requirement) constitutes an important and necessary step in understanding the overall performance of  membrane modules. But, the exact (numerical) solution methods suffer from the complexity of the solution. Therefore, solutions of nonlinear ordinary differential equations th...

Session Ii Membrane Separations

October 23-27, 2011 Gatlinburg, TN page 8 of 45 17th Symposium on Separation Science and Technology for Energy Applications agents for human applications are being developed. Toward this goal, we are testing in vivo efficacy of Cuprimine and Syprine therapeutics, that are approved by the U.S. FDA to treat copper overload in Wilson Disease (a genetic defect in copper metabolism and transport), f...

Functionalized Polymeric Membranes for CO2 Capture

Reducing CO2 emission and lowering the concentration of greenhouse gases in the atmosphere has quickly become one of the most urgent environmental issues. While a variety of technologies and methods have been developed, the separation of CO2 from gas streams is still a critical issue. Apart from establishing new techniques, the exploration of membrane materials with high separation performance ...
