351 Closed loop flare control using a video imaging spectral radiometerVideo Imaging Spectral Radiometry (VISR) has emerged as the only practical method to directly and continuously monitor flare performance. The VISR method provides real time measurements of flare combustion efficiency (%) and a smoke index (0-10) at a 1-sec temporal resolution. In addition to these t...

363 Combustion emissions and thermal performance impacts when replacing hydrocarbon fuels with hydrogen in industrial furnacesMany industrial processes rely on heating that is currently achieved through combustion of fossil fuels. The industrial sector generates approximately 23 percent of the greenhouse gas emissions in the US. As infrastructure associated with production and distribution of hydrogen continues to expand, ...
364 Combustion of municipal solid wastes with oil shale in a circulating fluidized bed1996-06-30The authors of this report have invented an integrated process for the treatment of municipal solid waste (MSW). In this process, after recycling steps to save usable materials such as aluminum, other metals, and glass have been completed, the resulting refusederived fuel (RDF) is co-combusted with ...
365 The coming boom in Utah's school age and college age populations: state and county scenarios2002-09Population analysts have for some time anticipated a significant increase in the school age population (5 through 17 years of age) of Utah beginning around 2004 and extending for at least a decade. At this point the question is not whether the boom will materialize, but rather, the exact timing, mag...

367 Common conditions for heavy oils1987Heavy oils; Colloidal admixtures; Hydrocarbons; Asphaltenes; Trace metals; Organic residues; Alberta basin; Eastern Venezuela basin; Athabasca; Orinoco; Heavy-oil depositys; Common conditions for heavy oilsField evidence suggests that conditions for the collection and retention of various hydrocarbons exert control over the composition of resident hydrocarbon mixtures. Heavy-oil deposits demonstrate that control very clearly. Heavy oils are essentially colloidal admixtures of hydrocarbons, usually acc...

375 Composition and origin of the Uinta Basin bitumens1963-01The names of the three formations of interest, from oldest to youngest, the Wasatch, Green River, and Uinta, have been used largely as facies terms to differentiate sediments which were believed to be of different age but actually were deposited simultaneously. The Wasatch is predominantly fluviatil...
