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...

Cracked Gas Compressor / Turbine

Mar 21, 2010
Ed Oberthier, Krishna Merchant
The cracked gas compressor (CGC) is still the most critical unit in the entire ethylene production facility. Its energy demand and potential plant run length, linked to its volumetric flow, molecular weight, pressure ratio and associated contaminant removal, is a major design element within the...

Turbomachinery for Mega-Ethylene Plants

Mar 21, 2010
Diane E Scheponik, Donald H. Mansfield
Ethylene producers continue to search for ways to improve capital expenditure versus payback ratio and to reduce installation and maintenance costs by benefitting from economies of scale. As ethylene plant outputs increase beyond the 1 million ton per year size, turbomachinery manufacturers must...

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...

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...

Instrumented Protective Systems for Distillation Operations

Mar 21, 2010
Jennifer Mize
Distillation is one of the most common unit operations in the chemical processing industry. Using relative volatility as a means of separating chemicals involves adding large amounts of energy to the system at the base of the column, typically through the use of a reboiler, and then removing that...

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...

A Guide to Developing and Implementing Safety Checklists: Plant Steam Utilities

Mar 21, 2010
Delmar Morrison
Steam generation is an integral part of most chemical process plants; however, the steam plant often is or can be overlooked in the area of hazard analysis. The reasons for this oversight are obvious: steam generation is considered to be an old and well understood process, and steam boiler systems...

Chronic Pain Resulting from Your Relief Device Management Systems

Mar 21, 2010
David A. Moore
With the increasing use of Layer of Protection Analysis as a semi-quantitative method of assessing process risk, LOPA practitioners are asked to assign credit to numerous safeguards including relief devices. Relief devices are only as strong as the initial design of the component and the systems...
