Processes using sulfur dioxide as oxidant instead of molecular oxygen, several of which were developed in the 1960s, have not become a factor in either natural gas or geothermal applications. With the exception of the IFP Clauspol process, which was tailored to Claus tail gas applications, none of these methods has been commercially successful. 

Bacterial Growth. One problem encountered in many Stretford plants treating gas streams other than coke-oven gas is contamination of the system by bacterial growth (Sundstrdm, 1979 Bromel, 1986). The problem can also be present but is quite rare in coke-oven gas or geothermal applications. The absence of bacterial contamination in these two types of Stretford plants is due to the presence of thiocyanate in the former, and boron compounds in the latter (boron in geothermal steam originates from radioactive decay within the earth s mantle). 

The screw expanders are widely used for waste heat recovery and geothermal applications. Reciprocating piston expanders have been used for the waste heat recovery of internal combustion engine exhaust. Screw and reciprocating piston expanders can be used... 

Compared with epoxy adhesives, polyimides share a very small part of the global market, limited to military, aerospace, and geothermal applications requiring long-term stability at elevated temperatures. Owing to their aromatic heterocyclic structure, virtually all polyimides are stable at 300 °C. When loaded with inorganic particles such as alumina, silica, silicon nitride, or aluminum, the thermal stability is still better. By contrast, some metals used in the composition of conductive adhesives, in particular silver and nickel, dramatically decrease the thermal resistance. This means that the adhesive strength of most polyimides is excellent at 200 °C,...

Direct geothermal energy is used for space heating of homes, greenhouses, livestock barns, and fish-farm ponds. As well, it is employed as a heat source in some industrial processes, such as paper production in New Zealand and diying diatomite in Iceland. Since the industrial applications usually require high-... 

Should geothermal be included as a green energy, given that projects deplete over time and release toxics in many, if not most, applications ... 

It may turn out that the same drilling technology that is being used to extract nil and gas, and that has been adapted for mining, geothermal, and water supply applications, will someday be equally useful in sequestering CO, in appropriate subsurface geologic formations.

Amine sulfide terminal moieties can be imparted into vinyl polymers by using aminethiols as chain transfer agents in aqueous radical polymerization [1182]. The polymers are useful as mineral dispersants. Other uses are as water-treatment additives for boiler waters, cooling towers, reverse osmosis applications, and geothermal processes and oil wells and as detergent additives... 

This paper evaluates the applicability of the modified precipitation rate equation in predicting the discharge duration of a calciting well compared to the observed utilization history and the results of the conservative method from direct deposition of excess calcite. Three wells in Mindanao Geothermal Production Field (MGPF) with documented output decline due to calcite deposition were studied, namely APOID, SP4D, and MD1D.
