Synthesis of Novel Catalyst for the Trireforming of CO2-Rich Flue Gases

Mar 15, 2011
Tracy J. Benson
Today’s chemical industry is very complex with most commodity chemicals being produced from some variation of petroleum feedstocks. From transportation fuels to polymers, petroleum is truly the largest source of basic hydrocarbons for which many of the common household products consumers use. Along...

LNG Tank Top Fires

Mar 15, 2011
James Venart
The regulatory requirements of 49 CFR 193, Liquefied Natural Gas Facilities: Federal Safety Standards, require thorough engineering reviews before approval of any proposed LNG facility. Such a process must consider potential and credible hazardous events. The proposed paper will specifically note,...

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...

Practices to Mitigate NOx Risk In Cryogenic Section of Ethylene Plants

Mar 15, 2011
Jennifer L. Bancroft
In May 2010 the Ethylene Producers Committee NOx Safety Sub-Committee sponsored a discussion on practices to mitigate NOx risk in the cryogenic section of ethylene plants. The meeting was attended by representatives of 10 ethylene producers, 4 ethylene contractors and other contractors, 2 additive...

Advanced Hydrogen Management : More Than a Balancing Act

Mar 15, 2011
Sanjiv Ratan
Modern high complexity refining landscape involves increasing proportion of “opportunity crude” processing and widened bottom-of-the-barrel strategies, which together with ever stringent ‘clean fuels’ requirements has led to extensive need for hydrogen and its optimization in the refinery. This in...

Investigation of the Adsorbed Species of CO2 on Mg(OH)2

Mar 15, 2011
James C. Fisher
Introduction Fossil fuels supply a majority of the world's energy needs. However, the combustion of fossil fuels is one of the major sources of the greenhouse gas CO 2 . Integrated gasification combined cycle (IGCC) is one the most efficient power generation systems that use coal. However, because...

Enhance Cracked Gas Compressor Reliability with Novel Antifoulant Technology

Mar 15, 2011
P. N. Ramaswamy
Enhance Cracked Gas Compressor Reliability with Novel Antifoulant Technology It is widely known that there is a potential for fouling in Cracked Gas Compressors within Ethylene plants. Gas crackers have generally had a higher fouling potential than liquid crackers due to the lack of aromatic...

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...
