As one of the major risks in high-sulfur crude oil processing, the H2S exposure could be reduced by early warning of H2S leakage. Based on the source and distribution of H2S, the four-level warning mechanisms of H2S leakage is developed by using HSE risk identification system, which makes the H2S concentration values as the grading index. The appropriate emergency measures are formed. To provid...

Effective utilization of byproducts can affect the profitability of kraft pulping to produce cellulosic fibers from wood. This review considers opportunities to use tall oil components, obtained from kraft pulping, as a source of raw material for biodiesel fuel, or as a source of additives for petrodiesel. Considerable progress has been achieved with respect to converting vegetable oils to dies...

Gourd seeds have been identified as a source of edible oil, but there is sparse literature on the effect of processing factors on the characteristics of oil extracted from any Lagenaria spp. Optimization of oil extraction with the aid of expeller was achieved by applying response surface methodology. The variables were roasting temperature (87.70-172.0°C) and roasting duration (7.93-22.07 min),...

While oil shale has the potential to provide a substantial fraction of our nation’s liquid fuels for many decades, cost and environmental acceptability are significant issues to be addressed. Lawrence Livermore National Laboratory (LLNL) examined a variety of oil shale processes between the mid 1960s and the mid 1990s, starting with retorting of rubble chimneys created from nuclear explosions (...
