Equilibrium and Kinetic Studies Carbon Dioxide Capturing on Ca-Based Sorbents

Mar 23, 2010
Jorge Pena Lopez
The increase of atmospheric carbon dioxide concentrations in recent years is well documented. Its potential link to an earth wide greenhouse-like effect has led recently to tighter regulations on carbon dioxide emissions from various industrial sources. One of the most common emitters is the fossil...

Full Potential Conversion of Vacuum Resids

Mar 23, 2010
Irv Wiehe
Present vacuum resid conversion processes, either coking or hydroconversion, are far from achieving their maximum conversion. With the remaining petroleum resources, on average, having a greater fraction of the vacuum resid fraction, it is imperative that new resid conversion processes or schemes...

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%,...

Safety Incidents in Ethylene Plants

Mar 23, 2010
Stephen De Haan
Many similar safety incidents occur in ethylene plants throughout the world. While these should be well known to plant operators, our paper lists these more common safety incidents along with their root causes. We then discuss several less common safety incidents that have occurred: • Heater over-...

Furnace Safe Park DCS Tool

Mar 23, 2010
Bryan McVicker
Properly managing the shutdown or “safe parking” of multiple steam-cracking furnaces during a plant-wide upset can be challenging. Alarm flood and multiple competing demands on operators are characteristics of such situations. The ExxonMobil Beaumont olefins plant has created a DCS interface to...
