Abstract: A system for geothermal process optimization can include a receiver configured to receive brine conditions sensed at a head of a production well of a geothermal power plant and a first circuit configured to determine an analyte value according to the sensed brine conditions. Also, the system can include a second circuit configured to determine a product dosage value for a product, according to the analyte value, product information, and historical power plant data. The product dosage value can be an amount of the product suggested to adequately prevent buildup, corrosion, or a combination thereof at a given part of the geothermal power plant, such as the production well.

Abstract: A composition and method for dispersing sulfur, cleaning sulfur deposits, and minimizing foaming in an aqueous system is disclosed. The method may include adding a first sulfur dispersant to process water containing sulfur and dispersing the sulfur. The first sulfur dispersant may include a C5-C25 alkyl polyglycoside. A second sulfur dispersant may also be added to the process water. The second sulfur dispersant may include a polymer of acrylic acid and 2-acrylamido-2-methylpropane sulfonic acid.
