The Destruction of Dioxins In Fly Ash by Using Gliding Arc In Tornado

Mar 14, 2011
Liang Yu
The characteristic of gliding arc in tornado was investigated under different experimental conditions and the destruction of PCDD/Fs (polychlorinated dibenzo-p-dioxins/polychlorinated dibenzofurans) in medical waste incinerator fly ash by using a dc gliding arc in tornado reactor was studied in the...

The Energy Challenge: Providing Sustainable Supplies to Meet Growing Demand

Mar 13, 2011
F. Emil Jacobs
As economies grow and living standards improve, the world faces a dual energy challenge: meeting the growing demand for energy while mitigating emissions and their impact on the environment. ExxonMobil believes that addressing this dual challenge requires an integrated set of solutions which...

A Compact Integrated Warm Syngas Overall Cleanup System

Nov 8, 2010
Liyu Li
Gasification of coal or biomass to syngas followed by catalytic synthesis of ammonia, hydrocarbons or oxygenates provides a feasible strategy to meet the increasing demand for fertilizers and transportation fuels. This syngas has many impurities, including As, Be, Cd, Cl, Cr, Hg, K, N, Na, P, Pb, S...

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%,...

Mercury Control with Regenerative Activated Coke Technology

Mar 21, 2010
James Peters
Many issues face coal fired utilities with respect to environmental demands, some based on regulations and others based on local pressures. These include increasingly stringent control of criteria pollutants, anticipated federal and state requirements for mercury control, issues revolving around...

On the Solubility of Mercury in Liquid Hydrocarbons

Mar 21, 2010
D. Gallup
The solubility of Hgo was determined in 34 pure hydrocarbons, hydrocarbon mixtures, crude oils, and water from -65oC to +65oC (where each solvent remained liquid). The solubility of HgCl2 was also quantified, but in a limited subset of the solvents. The solubility of any Hg species in its...

Thermodynamics for the Practicing Engineer

June, 2009
Thermodynamics for the Practicing Engineer, as the title suggests, is written for all practicing engineers and anyone studying to become one. Its focus therefore is on applications of thermodynamics, addressing both technical and pragmatic problems in the field. Readers are provided a solid base in...

Pollution Prevention: Methodology, Technologies and Practices

November, 1998
As many industries are beginning to learn, pollution prevention technologies offer more than just a way to comply with regulations, or even to “do the right thing.” It also makes smart business sense. The authors of this book, both veterans of DuPont’s in-house waste reduction team, have put...
