Carbon Capture and Storage - Can CCS Be a Viable Business?

Mar 21, 2010
Ray Hattenbach
Carbon capture and storage (CCS) has been characterized as the technology that can jump start mitigation of greenhouse gases until new, less carbon intensive technology can be implemented to provide electrical power, transportation fuels and energy our society needs to stay competitive in the world...

Energy Security and Affordability in the 21st Century

Mar 21, 2010
John Hofmeister
Hofmeister, former President of Shell Oil Company, and founder of the non-profit association, Citizens for Affordable Energy, tackles two of the most critical concerns facing industry today – energy availability and affordability. While green energy is helpful, it's inadequate for the demands of...

CFD Simulation of Diesel Hydrotreaters Under Periodic Operation Mode

Mar 21, 2010
Middle distillate hydrotreating is the most important refining process for the production of ultra-low-sulfur diesel, in which sulfur content is required to be less than 15 wppm. Hydrotreating is usually conducted in trickle bed hydrotreaters under steady-state operation with constant gas and...

Ensuring Reliability and Optimum Performance in Antisurge Applications

Mar 21, 2010
Janine Keeley
There are several compressors within an ethylene plant, cracked gas and refrigeration compressors are the major ones. These compressors are high capital cost items. Performance and reliability of these units are especially important. The antisurge control system is designed to protect this asset. A...

Process Gas Compressor Fouling & Washing Mitigation

Mar 21, 2010
Sheri R. Snider
Part A: The ethylene industry has been affected by the economic downturn. Plants have operated at low rates and have fed lighter feeds when possible. In this paper, the impacts of feed rates and types on process gas compressor operation and monitoring are discussed. Part B: Ethylene plant...

Nonlinear Model Order Reduction Using Block Structured Models for Large Processes

Mar 21, 2010
Omar Naeem
Please note: sound does not begin until approximately 30 seconds into the presentation. Typically mathematical models of physical and chemical processes are large and complex because of complications and nonlinearities of physical processes. The importance of mathematical models is evident for...

Progression of GHG Emissions Benchmarking

Mar 21, 2010
Claire Cagnolatti
The efforts to measure, regulate, and control the emissions of greenhouse gases (GHG) by the refining and petrochemicals industries have been in effect in varying degrees in several countries and regions around the world. Companies that operate such facilities in regions with pending or active...
