Method for reducing sulfur compounds in sulfur plant effluent |
May 25, 1976 |
| In the recovery of sulfur from hydrogen sulfide-containing gases wherein the first of a series of reactors is operated under conventional Claus conditions, one or more of the remaining catalytic reactors in the sulfur plant are operated at temperatures of the order of from about 250.degr |

Apparatus for using reheat gas in sulfur recovery systems |
August 16, 1977 |
| Proper reheat gas temperature is maintained in a sulfur plant operation at a high turn-down ratio by providing parallel flow paths in the boiler and withdrawing portions of the hot products from each of the flow paths and mixing with first condenser effluent to bring the gas to reaction |

Power auger seismic source |
August 24, 1976 |
| Seismic waves are generated by detonating an explosive gas mixture in an earth cavity formed by driving a short earth auger to a desired depth, leaving most of the augered earth in the hole surrounding the auger shaft, and then pulling the auger and shaft upwardly to lift and compress th |
