six feedstocks for biodiesel production, the sulfur content in the raw materials (oils or fats) was typically between 20 and 30 ppm, with the highest being 44 ppm. Although not reported here, after processing, the sulfur content (ppm) in the crude glycerol was generally higher than that in the raw oils (Thompson and He, 2006). This means that sulfur from

SO2 Manufacturing Process Sulfur Burning Plant

The SO2 Manufacturing Process is "simple", all you need is a sulfur burning plant. The flowsheet represent what you need for a sulfur burning system to produce SO2. Sulfur is supplied to the sulfur burner from a submerged gear pump located in the sulfur melter. The submerged pumps provide accuracy, reliability and ease of maintenance.

Large reduction in distillate fuel sulfur content has only

Large reduction in distillate fuel sulfur content has only minor effect on energy content. Sulfur is removed from distillate fuel during the refining process by reaction with hydrogen. This process, known as catalytic hydrotreating, strips away sulfur as well as nitrogen, oxygen, and metals from hydrocarbon compounds.
