Jul 11, 2007 The sulfur is then stripped from the amine to make H2S which then goes to the Sulfur Removal Unit which removes the sulfur. It is stored at 290F (in molten form it looks like motor oil), typically in pits heated with steam coils and then shipped it out in rail cars to pharmeceutical companies, fertilizer manufacturers and also the makers of soap.
Sulfur recovery is an important process for natural gas processing plants and refineries. The raw feed streams often contain gases, such as H 2 S and CO 2.H 2 S is a highly toxic gas and contributes to SO 2 emissions. To comply with environmental regulations, the sulfur species are converted to elemental sulfur and water via sulfur recovery technologies such as Claus
thumb for sulfur recovery are compiled. Background Acid Gas Removal The acid gas is the starting point for any study concerning the sulfur recovery unit. A sour gas contains H 2 S and CO 2 among other less concentrated sulfur containing compounds. Generally, H 2 S and any other sulfur components are desired to enter the SRU.

CS2 as a product typically result in a reduction in overall sulfur recovery. The hot gases from the Reaction Furnace flow through the tubes of the Waste Heat Boiler (WHB) the gases are typically cooled to 550-600F by generating steam on the shellside of the WHB. Low, medium, or high pressure steam may be generated in the WHB.

Mar 24, 2008 The sulfur is burned in air to SO2, which is then catalytically converted to SO3. The SO3 is dissolved in 98% H2SO4 to make fuming sulfuric acid (104% H2SO4) , which is diluted back to 98% for product. Oil sludge takes as much as 15 times the acid plant capacity as elemental sulfur fo rthe same 98% acid production. _____

Treatment of high-strength sulfate wastewaters is becoming a research issue not only for its optimal management but also for the possibility of recovering elemental sulfur. Moreover, sulfate-rich wastewater production is expected to grow due to the increased SOsub2/sub emission contained in flue
Abstract. Liquid redox sulfur recovery processes absorb H/sub 2/S from gas streams and produce elemental sulfur for sale or disposal. These processes, which involve the overall reaction of H/sub 2/S with oxygen to form elemental sulfur and water can be used in a wide variety of applications where H/sub 2/S removal and recovery are required.
