Method for restoring geothermal water to underground
专利汇可以提供Method for restoring geothermal water to underground专利检索，专利查询，专利分析的服务。并且PURPOSE: To prevent the decrease of the capacity of a restored well and the closure thereof by burning a gas contg. H
2 S of a plant utilizing the terrestrial heat to produce SO
2 , converting it into SO
3 with the catalytic conversion, absorbing and treating SO
3 with concd. H
2 SO
4 after the precooling and thereafter sending the concd. H
2 SO
4 together with hot water to the restored well.
CONSTITUTION: A noncondensed gas contg. H
2 S is sent to a combustor V-4 from a condenser V-2 and burnt with air to produce SO
2 and the gas drawn therefrom is sent to a reactor V-6 and oxidized to SO
3 with a catalyst consisting essentially of V
2 O
5 . Then the gas is cooled with a heat exchanger V-7 and sent to an absorption tower V-8 and absorbed with concd. H
2 SO
4 . The concd. H
2 SO
4 incorporated in a concd. H
2 SO
4 vessel L-3 is sent to a chemical tank L-5 and diluted with water and thereafter restored to the underground together with hot water via a restored well W-2. In this case, pH of hot water is controlled to 1W4 with a sensor M-2.
