Reducing the Load on Cooling Towers through Revamping of Individual Coolers

Mar 14, 2011
Graham T. Polley
The engineering of cooling water systems involves a consideration of both hydraulic and thermal behaviour. Unfortunately this is often ignored. For instance when engineers seek to reduce the thermal load on cooling towers they will often opt for increased heat recovery (via improved heat...

In-Detail Chemistry of Hydrocarbon Partial Oxidation Reaction by Plasma

Mar 14, 2011
Dae Hoon Lee
In the plasma reforming of hydrocarbon fuels, especially in a partial oxidation process, characteristic parameters of the reaction can be sorted as plasma parameter and reactant condition parameter. Plasma parameter or electric power and voltage-current characteristic determines density of active...

Improved LNG Plant Performance Through Higher Thermodynamic Efficiency

Mar 14, 2011
Christopher M. Ott
For many years, the LNG industry has focused on large baseload plants. Recently, more attention is being given to smaller LNG facility sizes and alternative liquefaction strategies. This presentation will examine the impact that the thermodynamic efficiency of a particular cycle can have on the...

Chemical Insights Indicate Process Opportunities for Residue Processing

Mar 14, 2011
Murray R. Gray
The vacuum residue fraction of petroleum is one of the most complex mixtures of compounds known, one which continues to defy comprehensive analysis. The combination of complexity, diversity, and aggregation of the asphaltenes has enormous implications for upgrading reactions and phase behaviour...

Thermal Plasma Gasification of Different Coals with Carbon Dioxide

Mar 14, 2011
Maoqi Feng
Carbon dioxide emissions from conventional coal-fired power plants constitute the majority CO 2 emissions in the U.S. Mitigation of CO 2 by chemical conversion provides an alternative method to reduce the CO 2 emissions from coal gasification process with the benefit of eliminating energy-intensive...

Multi-Model MPC for a Complex pH Neutralization Process

Mar 14, 2011
Weiting Tang
Control of feed pH control is an important task in chemical industries, wastewater treatment, polymerization reactions, fatty acid production and biochemical processes. However, this is a challenging problem due to (i) presence of large and varying time delays and (ii) complex time varying...

Plasma Assisted De-NOx In Diesel Engine

Mar 14, 2011
Dae Hoon Lee
Plasma assisted De-NOx systems in mobile application are introduced. In general, de-NOx process requires reductant for reducing catalyst. NH3(Urea) fueling, post injection of diesel fuel are representative of method for supplying reductant. Here, using synthesis gas by on board reforming as...

Synthesis Gas Cleanup with Nonthermal Plasma

Mar 14, 2011
Maoqi Feng
Plasma processes are very useful in industry because plasma has the unique characteristic of producing active species in large numbers of energetic species than conventional chemical processes. Nonthermal plasma (NTP), such as corona or glow discharge plasmas, is widely used for generating such...

The Impacts of Tight Gas and Shale to Global LNG Market and Gas

Mar 14, 2011
Jonathan T. Kwan
“Do we have enough gas?” This question asked by former Federal Reserve Chairman Alan Greenspan in 2003 had prompted him to declare that the US did not have enough natural gas and would be necessary to import liquid natural gas (LNG) to fill the gap of US gas consumption. Many energy companies...

Study on Energy Consumption for Natural Gas Liquefaction

Mar 14, 2011
Qiang Xu
The main purpose of this work is to optimize natural gas liquefaction process by reducing energy consumption. At first, a rigorous simulation of natural gas liquefaction is conducted. Based on the simulation results, the refrigerants and natural gas thermodynamic states along with whole process are...

Secondary Effects of Reducing Carbon Dioxide Emissions

Mar 14, 2011
Eloy Flores III
Secondary Effects of Reducing Carbon Dioxide Emissions While climate change has lost some interest to the global economy, the United States and the World continue to move forward on advancing research and technologies to capture, sequester, or reuse the green house gas carbon dioxide. Capturing...

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...
