Conference Paper
Full-text available
Western Canada is well-positioned to play a critical role in exporting liquefied natural gas (LNG) to Asian markets as the world transitions to lower carbon-intensive fuels. LNG Canada, a $40 billion LNG export facility under construction in Kitimat, British Columbia (B.C.), can export approximately 3.5 Bcf/d at full capacity upon completion in 202...
Conference Paper
Full-text available
Not all liquified natural gas (LNG) is created equal. The energy required to liquefy and ship LNG impacts the greenhouse gas (GHG) emission intensity along the entire value chain, thereby impacting the net benefit to global GHG reduction efforts. This research compared the GHG intensity of LNG that will be exported from LNG Canada’s export facility...
Poster
Full-text available
Liquified natural gas (LNG) generates fewer greenhouse gas (GHG) emissions than coal, which could help combat climate change. Western Canada is uniquely positioned to provide LNG to Asian markets, but progress has been stymied by a lack of export capacity. This research quantified the net benefit of LNG development using a case study: what happens...
Article
A source of sand is proposed as an educational tool to aid in the identification of silica mineralogies and textures susceptible to alkali-silica reaction. This particular silica sand originates in the southern portion of the state of Veracruz, Mexico, and exhibits a wide variety of lithologies, A thin section produced from a cross-section through...
Article
During boiler operation the concentration of water impurities can cause harmful effects such as scale deposits, corrosion, and embrittlement. Periodic water removal (blowdown) is necessary to maintain boiler operation, but introduces the problem of how to manage the waste brine material. This study explores the utilization of a simulated boiler blo...
Conference Paper
Full-text available
The strain distribution and strain concentrations that lead to fractures in concrete weight coating (CWC) for pipelines have been extensively studied. However, to the extent of the authors' knowledge, the development and propagation of cracks during the loading, and their influence on the composite behavior has not been as thoroughly examined. This...
Article
Fresh concrete exposed to a drying environment is susceptible to plastic shrinkage cracking, which can result in negative impacts on concrete durability. In the current ASTM standard, plastic shrinkage cracking is evaluated by the average crack width measured at 24 h after concrete placement, considering that the traditional crack measurement tools...
