Evaluation of Alternative Fuels to Replace Coal In Cement Manufacturing

Oct 17, 2011
Steve R. Duke
A multiyear DOE-supported study was completed to identify, determine, and understand fundamental burn characteristics and properties of alternative fuel sources to replace coal for energy generation, with emphasis on impacts in cement processing. Portland cement manufacturing involves the...

Deepwater Drilling Regulations In the Gulf of Mexico

Oct 16, 2011
Ian Sutton
Deepwater Regulations in the Gulf of Mexico The Deepwater Horizon incident (DWH) of April 2010 led to many changes in deepwater operations in the Gulf of Mexico. Not the least of those changes were to do with regulations. In the three months following DWH two important changes to the regulatory...

Alan Rossiter

In this webinar the major approaches are classified into three categories: optimization of current equipment and operations, implementation of economic investments, and sustainment activities.

Operational Inputs Into the Mechanical Integrity Program

Mar 15, 2011
F. Russ Davis
A predictive mechanical integrity (MI) program is based on the following: * Damage mechanisms that affect process equipment. * Rate at which degradation progresses. * Ability of the inspection group to identify and correct equipment damage before equipment failure. Operational temperature, pressure...

The Role of Heat Exchangers In Post-Combustion CO2 Capture

Mar 14, 2011
Warren H. Ziegler
The role of heat exchangers in post-combustion CO2 capture Warren Ziegler Motivation: The overall energy penalty for post-combustion carbon capture by aqueous amines as well as solid sorbent systems can be reduced significantly by recovering heat from the lean/hot solvents coming out of the...

Resin Wafer Electrodeionization for Flue Gas Carbon Dioxide Capture

Mar 14, 2011
Rebecca L. Stiles
Energy efficient capture of CO 2 from coal-fired power plants is one of the grand challenges for the U.S. both to end dependence on imported energy and to reduce greenhouse gas emissions. Nalco Company and Argonne National Laboratory received a Department of Energy ARPA-E award to develop Resin...

Role of Plasma Chemistry In Fuel Reforming Process

Mar 14, 2011
Young-Hoon Song
The purpose of the present study is to investigate role of plasma chemistry in a fuel reforming process. So far, role of plasma chemistry in a fuel reforming process has been a controversial issue, since coupling of plasma chemistry and thermal chemistry in fuel reforming process is inevitable...

Plasma Assisted Combustion for Environmental Applications

Mar 14, 2011
Young-Hoon Song
In the early part of the presentation, a detailed application of a plasma assisted combustor operated in a diesel exhaust line for regenerating DPF (Diesel Particulate Filter) are introduced. In this plasma assisted combustor, rotating arc is generated by a high voltage AC power and tangentially...

Mercury Removal From Gaseous and Liquid Hydrocarbons

Mar 13, 2011
Neil Eckersley
Mercury is present in many of the world’s oil & gas fields and its removal and capture is important for a number of reasons: * Process plants with brazed aluminium heat exchangers are susceptible to corrosive attack by mercury * Product streams eg. naphtha are less valuable to producers when “...

Energy (South Texas Section March 2011 Meeting)

South Texas Section Webinar
Mar 4, 2011
Mark Holtzapple

Dr. Holtzapple will describe the challenges of providing energy to a growing world. To address energy needs, he will show how the MixAlco process converts waste biomass into bio-gasoline.

Design Enhancements of a High Temperature, Ceramic Micro-Channel Heat Exchanger

Nov 9, 2010
Merrill Wilson
The recent developments in the energy and process industries have lead to more efficient, higher-temperature processes and compact equipment. By using small features such as micro-channels, pin fins or plate fins the length scale for which transport occurs is minimized and thus increases the heat...

Fouling Monitoring Techniques for Water Treatment Membrane Processes

Nov 7, 2010
Kuo-Lun Tung
Membrane fouling and flux decline are undesirable, albeit inevitable, problems in membrane filtration processes for water treatment. The development of low fouling membranes, the design of high efficiency modules, the selection of optimal operational strategies, and several improvements made in...
