Based on a presentation to the 4th International Pipeline Conference, Sept. 29-Oct. 3, 2002, Calgary. The research described here examined the fate of H 2 S-contaminated natural gas slugs as they ...

Gas transport through a metal cluster-containing crystalline solid. Hydrogen and carbon monoxide travel at different speeds due to their molecular size relative to the size of nanoscale tunnels in the ...

An accelerated field measurements program was conducted to quantify atmospheric diffusion within a deep, steep-walled canyon in rough, mountainous terrain. Two principle objectives were pursued : ...

Adjustments to a pipeline’s cathodic-protection program can help address possible hydrogen diffusion brought about by nonconformance with welding procedure specifications (WPS) during construction.
