Nevertheless, extracting the sulfur created serious ecological hardship on the country. [7] By 1912 the United States overtook Sicily for the worldwide production of sulfur. Large consistent bases of sulfur in Texas and Louisiana, as well as low-cost fuel and large quantities of water, made the newly invented Frasch process economical. [5]
The sulfur is recovered as concentrated sulfuric acid and the nitrogen oxides are reduced to free nitrogen. The process is based on the well-known wet sulfuric acid process (WSA), a process for recovering sulfur from various process gasses in the form of commercial quality sulfuric acid (H 2 SO 4).

Below is a schematic flow diagram of an IGCC plant: Block diagram of IGCC power plant, which utilizes the HRSG. The gasification process can produce syngas from a wide variety of carbon-containing feedstocks, such as high-sulfur coal, heavy petroleum residues, and biomass.
The second Frasch-process mine opened in 1912 in Brazoria County, Texas. The Gulf Coast came to dominate world sulfur production in the early and middle 20th century. [7] However, starting in the 1970s, byproduct sulfur recovery from oil and natural gas lowered the price of sulfur and drove many Frasch-process mines out of business.
The synthetic fuel is extremely clear because of the near-total absence of sulfur and aromatics. Synthetic fuel or synfuel is a liquid fuel, or sometimes gaseous fuel, obtained from syngas, a mixture of carbon monoxide and hydrogen, in which the syngas was derived from gasification of solid feedstocks such as coal or biomass or by reforming of ...
The Bergius process is a method of production of liquid hydrocarbons for use as synthetic fuel by hydrogenation of high-volatile bituminous coal at high temperature and pressure. It was first developed by Friedrich Bergius in 1913.
In 2010, INFRA built a compact Pilot Plant for conversion of natural gas into synthetic oil. The plant modeled the full cycle of the GTL chemical process including the intake of pipeline gas, sulfur removal, steam methane reforming, syngas conditioning, and Fischer–Tropsch synthesis. In 2013 the first pilot plant was acquired by VNIIGAZ ...
