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...
Aqueous Morpholine As a Potential Post-Combustion CO2 Absorption Solution
Nov 1, 2012
Krishna Mohan Jinka
Due primarily to high cyclic capacity and high absorption rates compared to other methods, aqueous amine based CO 2 capture has gained great interest for application to post-combustion CO 2 capture. While aqueous amines have a long history for acid gas removal, challenges remain for the commercial...

Shale Gas Brightens Outlook for U.S. Chemicals
Martha Gilchrist Moore, T. Kevin Swift
The chemical industry will experience moderate annual growth over the next few years — ranging between 2.2% and 4.6% through 2017. The higher growth rate accounts for new investments announced in response to the abundant supply of shale-based...
Optimizing an Organic Rankine Cycle
Alan Winstead, Ali Bourji, P.E.
An organic Rankine cycle (ORC) system can be a cost-effective way to convert waste heat to electricity. The key is finding the best ratio of net power recovery to capital cost.
