November
2004
Reactions and Separations
Christopher J. Ramsey, David S. Dickey, Keith E. Johnson , Kevin J. Bittorf
Physical modeling and computer simulation provide insights into the performance of a glass-lined reactor.

Use Oxygen to Improve Combustion and Oxidation

July
2010
Reactions and Separations
Nancy C. Easterbrook, Reed J. Hendershot, Timothy D. Lebrecht
Substituting oxygen for air is often a low-cost, easy-to-implement option that can reduce capital costs, lower emissions, and improve process flexibility and reliability.
