Cost Effectiveness of 2-Row Membrane System for FLNG

Apr 3, 2012
Herbert Moon
One of the most critical issues in engineering and design of FLNG is to reduce top side weight along with its load distribution to the sub-structure. Concentrated top side loads will result in an increase in hull structure costs. The developed 2-row containment system allows flexibility of top side...

Application of the Anti-Sloshing Blanket to LNG Carriers and FLNG

Apr 3, 2012
Sangeon Chun
Sloshing is long problematic issue on achieving safety and reliability of LNG carriers and FLNG if the liquid level is below at a certain point in the containment system. Sloshing motion can be significantly reduced by covering the free-surface using a patented floater type blanket which is formed...

Refinery-Wide Topics for Profitability, Reliability and Safety

Apr 3, 2012
Mike Siravo
In this session we will review several case studies that will allow you to better understand the importance of process engineering and process safety basics. These examples will show specific pitfalls to avoid but also will open your thinking to properly consider the implications of other...

Refining Energy Utilization and CO2 Emissions Modeling

Apr 3, 2012
John J. Marano
The U.S. petroleum refining sector consumes large quantities of energy in order to convert crude oil into transportation fuels and other products. According to the Energy Information Administration, the sector consumed 31% of total U.S. industrial energy in 2006, resulting in significant CO 2...

Nathan A. Hatcher
Fate of Ammonia in Refinery Amine Systems Ralph H. Weiland, Nathan A. Hatcher & R. Scott Alvis Optimized Gas Treating, Inc. Sugar Land, TX ABSTRACT Ammonia ingress and accumulation in refinery and bio-gas amine systems is not a new problem. However, increasing utilization of advantaged crudes...

Waste Heat Recovery Considerations in LNG Plants

Apr 2, 2012
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,...

Future Fuels and Chemicals: Grand Challenges and Opportunities

Apr 2, 2012
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...

Tutorial: The Chemistry of Refinery Fouling

Apr 2, 2012
Irv Wiehe
The chemistry of refinery fouling is well enough understood to mitigate nearly all fouling. The key information required are the location of the foulant, elemental analysis of the foulant, and identification of precursors in the oil flowing through the fouled unit. Most organic fouling is caused by...

Asphaltene Instability Measured by Small-Angle Neutron Scattering

Oct 19, 2011
Michael P. Hoepfner
Asphaltenes are defined as the petroleum fraction that precipitates with the addition of a normal alkane; however, it was only recently discovered that there is a strong time-dependency for precipitation in oil/n-alkane mixtures [1]. It was found that at low precipitant concentrations, asphaltenes...
