Herman FraschDied 1 May 1914 at age 62 (born 25 Dec 1851).German-born American petroleum scientist who invented the Frasch Process for sulphur mining. Patented in 1891, his method made it economically possible by a process of drilling, melting and pumping to extract sulphur from underground deposits as found in Louisiana and in eastern Texas. A hole is drilled into the sulphur bearing formation and cased. Then, three concentric pipes are placed within the protective casing to facilitate pumping super-heated water down the hole melting the sulphur and recovering the molten sulphur to the surface. It made possible the exploitation of extensive sulfur deposits otherwise obtainable only at prohibitive expense.« |
