Abstract
A method of suspending elemental sulfur in water includes the steps of providing water including elemental sulfur and hydrogen sulfide and adding from about 1 to about 100 parts by weight of a sulfur suspension additive to the water based on one million parts by weight of the water to suspend the elemental sulfur in the water. The sulfur suspension additive is chosen from an alkyldiphenyloxide disulfonate or salt thereof, a secondary alcohol ethoxylate, a non-ionic ethylene oxide and/or propylene oxide copolymer, and combinations thereof.
Claims14
A method of suspending elemental sulfur in water in a geothermal fluid, said method comprising the steps of:
- A. providing the geothermal fluid comprising water, elemental sulfur and hydrogen sulfide in a geothermal power plant;
- and
- B. adding from about 1 to about 100 parts by weight of a sulfur suspension additive to the geothermal fluid based on one million parts by weight of the water which suspends the elemental sulfur in the water,
- wherein the sulfur suspension additive is an alkyldiphenyloxide disulfonate or salt thereof.
A method of suspending elemental sulfur in a geothermal fluid, said method comprising the steps of:
- A. providing the geothermal fluid comprising water, elemental sulfur and hydrogen sulfide in a geothermal power plant;
- and
- B. adding from about 10 to about 50 parts by weight of a sulfur suspension additive to the geothermal fluid based on one million parts by weight of the water to suspend the elemental sulfur in the water,
- wherein the sulfur suspension additive is an alkyldiphenyloxide disulfonate or salt,
- wherein the alkyldiphenyloxide disulfonate or salt thereof has the following structure:
- wherein R is an alkyl group having from 10 to 16 carbon atoms and each X is Na+, and
- wherein the step of adding creates a mixture that has an optical density of at least 0.05 measured at 230 nm using a UV-V is spectrophotometer when the water comprising the elemental sulfur and the hydrogen sulfide and free of the sulfur suspension additive has an optical density of about 0.006 measured at 230 nm using a UV-V is spectrophotometer.
A geothermal system comprising:
- at least one of a geothermal heat exchanger, a geothermal cooling tower, and/or a geothermal pipe;
- and
- a geothermal fluid comprising suspended elemental sulfur disposed in the at least one heat exchanger, cooling tower, and/or pipe,
- wherein the geothermal fluid comprises:
- water;
- elemental sulfur and hydrogen sulfide;
- and
- a sulfur suspension additive that is an alkyldiphenyloxide disulfonate or salt thereof,
- wherein the sulfur suspension additive is present in an amount of from about 1 to about 100 parts by weight per one million parts by weight of the water.
