Successful Energy Stewardship

Mar 22, 2010
An energy stewardship program, aimed at driving energy efficiencies from no-cost operational improvements has been implemented with considerable success across the Valero refining system. Two years since commencement of the program roll out, energy use has been reduced by 5% and over $140 million...

Ship-Shore Interaction and LNG Tank Piping Design Considerations

Mar 22, 2010
Chen-Hwa Chiu
This paper intends to discuss one of the most neglected areas in the LNG plants. This area involves the ship-and-shore operating philosophy and interaction and BOG (boil-off gas) management. It involves the design considerations, operating philosophy and safety aspects of the LNG plants. It also...

Advances in Renewable Jet Technology

Mar 22, 2010
Use of aviation fuel currently corresponds to 2-3% of the total fossil fuels used worldwide, or 13% of fossil fuel used in transportation fuel. Aviation fuel use is the second biggest sector after road transportation, which consumes 80 percent. Further, the aviation industry is expecting to grow at...

Improved Energy Efficiency in CDUs Through Fouling Control

Mar 22, 2010
Jimmy D. Kumana
Crude oil distillation accounts for a large fraction of the energy used in oil refining. Crude oil contains a variety of substances which tend to deposit as fouling layers in heat exchangers, and this results in decreased energy recovery and requires increased energy input to the furnace. CDU pre-...

Tutorial on Using New Multivariable Solutions to Improve Flow Best Practices

Mar 22, 2010
Nathan Stokes
New advancements in multivariable pressure transmitter technology allow you to improve your flow measurement practices. By better understanding these advancements, you will be better able to quantify and optimize installed performance, select the right combination of compensation for a specific...

Advances in LNG Expander Technology

Mar 22, 2010
Joel Madison
The first use of cryogenic liquefied gas expanders dates back to the late nineties. The proven advantages of incorporating liquid expanders in the LNG liquefaction process lead the way to equip every new liquefaction plant with LNG expanders. The basic design concept of cryogenic expanders has...

Variability, Inventory Uncertainty and Supply Chains

Mar 22, 2010
Tony Cooper
This session will develop a fundamental understanding of how cycle time variation in stages of a supply chain propagates into measures of overall cycle time. Application can be seen in supply chains and inside plants with batch processes. While the sources of variation are symmetrical and can be...

Deployment of ZeaChem's Sustainable Biorefinery

Mar 22, 2010
Tim Eggeman
Increased emphasis is being placed on renewable, sustainable, domestic forms of energy, including transportation fuels, at national, state and local levels. Successful deployment of alternative solutions to petroleum-based liquid fuels for the transportation industry is dependent upon technical,...

Holistic Approach to the Revamping and De-Bottlenecking of Pre-Heat Trains

Mar 22, 2010
Graham T. Polley
The energy efficiency and throughput of pre-heat trains can be improved by using process integration and through fouling mitigation. In this paper we show how the approaches can be combined in a systematic way. If fouling behaviour is ignored the use of process integration can lead to revamps in...

Overcoming Logistical Challenges with Collaborative Technologies

Mar 22, 2010
Curt Hertler
All refiners—and manufacturers in general—face daunting logistical challenges including supply chain, changing product specifications, carbon legislation, and regulatory compliance. In addition, the industry faces knowledge management issues due to the reality of an aging work force. Information...
