Acceptable Operating Parameters for Steam Assisted Flares At Purge Rates

Apr 2, 2012
Tom Farmer
Recent field observations by TCEQ have revealed what appears to be poor flare destruction efficiency by some steam and air assisted flares when operating at turndown condition. Using specialized infrared cameras, unburned hydrocarbons were detected coming from improperly operated flare systems...

Application of Exergy Analysis for LNG Plants and Receiving Terminals

Apr 2, 2012
Chen-Hwa Chiu
Natural gas liquefaction is an energy-intensive process. New world scale LNG plant usually has multiple trains with each train has a very high capacity (up to 8 million tons per annum of LNG). Increasing the plant efficiency can increase LNG plant output and economics, with reduced greenhouse gas...

Future Fuels and Chemicals: Grand Challenges and Opportunities

Apr 2, 2012
Joseph Powell
To insure a Sustainable Future, CO 2 emissions must be reduced despite strong future growth in demand. “Easy oil” from conventional production will be less abundant, though coal and natural gas, as well as unconventional hydrocarbon reserves will remain in strong supply for decades to come. Carbon...

Douglas Wiles
WASTE HEAT RECOVERY CONSIDERATIONS IN LNG PLANTS ABSTRACT DOUGLAS WILES, RYAN HOLLENBACH & STANLEY KWAN Thermal integration in an LNG plant improves its overall thermal efficiency. Thermally integrated plants tend to have lower operating costs and reduced environmental emissions including, CO,...

Maximizing LNG Capacity for Liquefaction Processes Utilizing Electric Motors

Apr 2, 2012
Jonathan Berg
In some locations currently being considered for LNG projects, relatively low cost electricity from the local power grid may be available. For these facilities, refrigeration compressors driven by electric motors drawing power from the grid may be attractive. The fuel requirements for these plants...
