Stable Facilitated Transport Membrane For Olefin/Paraffin Separation

May 2, 2013
Ali Hamza, Glenn Towe, Majid Keyvani
Currently, the separation of olefins (ethylene, propylene) from paraffins (ethane, propane) on a commercial scale is accomplished almost exclusively by cryogenic distillation in petrochemical industries and is considered highly energy intensive. Consequently, there is an enormous economic incentive...

Mass Transfer Evaluation of CO2 Absorption in a Wetted Wall Column

Nov 1, 2012
Reynolds A. Frimpong
The chemical absorption of CO 2 in solvents is considered as one of the mature process options for reducing CO 2 emissions in power plants. Solvents with fast mass transfer rates and high CO 2 carrying capacity are therefore desired and continue to be explored to reduce equipment size and its...

Evaluation of Mercury Capture Technology Using Various Sorbents Injection

Nov 2, 2012
Xiaofei Wang
Coal combustion is a single largest known anthropogenic source for mercury (Hg) emission. Recently, US EPA has proposed Mercury and Air Toxics Standards (MATS) in order to regulate emissions of Hg and other pollutants. Many Hg control technologies have been developed, such as activated carbon...
