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...

Stability Analysis of Safety Valve

Mar 22, 2010
The stability for a safety valve was investigated by experiments and analysis. It was found that the dynamic instability was caused by the interaction effect between the pressure wave propagation through the inlet pipe and the valve disc motion. This dynamic instability is mitigated by the...

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-...

Mar 22, 2010
Hans Boot
Dutch legislation on safety and land use planning: Being a densely populated country, the Netherlands has extensive experience using safety regulations in land-use planning. Risk criteria have to be verified in urban development planning. Individual (Locational) Risk (IR) is easy to illustrate...

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...
