Hybrid Membrane Absorption Process for Post Combustion CO2 Capture

Mar 23, 2010
S. James Zhou
Gas Technology Institute (GTI) and PoroGen Corporation are jointly developing a novel hybrid membrane – absorption process for pre- and post-combustion CO2 capture (Carbo-Lock™ process). The novel Carbo-Lock™ process combines advantageous features of both absorption and membrane processes to...

Stripper Configurations for CO2 Capture by Aqueous Amines

Mar 23, 2010
David H. Van Wagener
A monumental task for improving the feasibility of carbon capture from the flue gas of coal-fired power plants is reducing the total energy cost. A generic absorption/stripping process using an aqueous amine solvent would reduce the net power production of a coal-fired power plant by roughly 30%,...

Real Time Detection of Gaseous Metal Contaminants in Coal Flue and Fuel Gas

Mar 21, 2010
Erik C. Rupp
The Integrated Gasification Combined Cycle (IGCC) is a promising technology for the future use of coal to provide energy. During this process, many of the trace elements present in coal are volatilized, and remain in the gas phase through the gas turbine, only to be released in the flue gas. Trace...

It is impossible to imagine modern life without the products provided by the petrochemical industry. These products are used in health care, consumer products, transportation, food processing, electronics, and construction.

Identification of Cleaner Production Improvement Opportunities

February, 2006
Regardless of its size or nature, every industry generates waste and is responsible for imple-menting the practices of pollution prevention and waste minimization in its day-to-day operations. Whether it's dirty water or toxic wastes, industrial pollution is all the same in one way: it reduces a...

Environmental Management
E. Joseph Duckett
Size does matter - and bigger is not necessarily better when it comes to pollution control. It is more important to be the right size than the largest size.
