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...

New Cooling Application: Total Heat Removal From Base Load LNG Plants

Mar 14, 2011
J. C. Kuo
Most new and existing liquefied natural gas (LNG) plants have used dry air cooler (DAC) technology to reject the total heat required to liquefy natural gas. Only a few others are able to overcome environmental issues such as thermal pollution and water limitations using water cooler (WC) technology...

Steam Utility Systems Are Not "Business as Usual" for Chemical Process Simulators

Mar 14, 2011
Jonathan Currie
The operating costs of a typical refinery utility system are so significant that small operational improvements can result in large annual savings. This paper introduces a new utility modelling package designed for PETRONAS to allow in-house modelling and optimization of their refinery and...

New Continuous Coking Process

Mar 14, 2011
Douglas W. Sullivan
NEW CONTINUOUS COKING PROCESS A new coking process can accept resid feed from the conventional resid heater in a coking plant and continuously discharge vapor and dry petroleum coke particles. The process promotes a rapid recovery of volatiles from the resid enabling recovery of more volatiles. It...

Handling LPG Components In LNG Plants

Mar 14, 2011
Stanley Huang
Natural Gas Liquid (NGL) recovery is an inherent part of most Liquefied Natural Gas (LNG) production trains. The requirement serves many purposes, such as adjusting the heating value of the product LNG, mitigating the freezing risks caused by specific intermediate and heavy components, and...

Using a Continuous MPC Algorithm to Control An Unsteady Batch Fermentation Process

Mar 14, 2011
William Stewart
Classical MPC has been leveraged to improve control on a nonlinear unsteady-state system, batch alcohol fermentation. The controller uses a hybrid model with fundamental reaction equations along with empirical process data-based modeling. More than thirty lines of batch quality control have been...

Efficient Power Recovery In LNG Regasification Plants

Mar 14, 2011
Hans E. Kimmel
Regasification plants vaporize liquefied natural gas using mainly high-pressure LNG pumps and heat exchangers. The vaporization pressure corresponds to the natural gas pipe line pressure. Due to the large temperature difference between the LNG feed and the pipe line gas, a substantial power...

Predicting Operating Regimes In Heavy Gas Oil Hydrotreating Reactors

Jinwen Chen
Predicting Operating Regimes in Heavy Gas Oil Hydrotreating Reactors Jinwen Chen and Mugurel Munteanu CanmetENERGY, Natural Resources Canada One Oil Patch Drive, Devon, AB, T9G 1A8, Canada Hydrotreating (HDT) or mild hydrocracking (HDC) of heavy gas oil or vacuum gas oil is an important step in...

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...

Glid ARC Plasma Conversion of Pyrolysis Gas Into Syngas

Mar 14, 2011
Fela Odeyemi
Pyrolysis gas is a product of Biomass, Municipal Wastes or Coal gasification process that contains H2, CO as well as unreacted light hydrocarbons and heavy hydrocarbons such as tar. These undesired hydrocarbons diminish Pyrogas fuel value thereby making significant removal of the unwanted...

Helium Extraction From Nitrogen Rejection Unit Stream of LNG Plants

Mar 14, 2011
Chen-Hwa Chiu
Helium is a major rare gas that has a lot industrial and research application. Potential production has traditionally come from natural gas and the helium market is becoming tighter as the production is not being kept up with the demand. Helium extraction and refining from the NRU (nitrogen...

Exploitation of Low-Grade Heat In Site Utility Systems

Mar 14, 2011
Ankur Kapil
The site utility system provides the heating, cooling load along with power production for the processes on the total site. Low-grade heat is available in large amount across the process industry from temperatures of 30 o C to 250 o C as gases (e.g. flue gas) and/or liquids (e.g. cooling water)...
