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.

First claim

The invention claimed is:

1. A method comprising:
receiving, at a receiver, first brine conditions sensed at a first part of a geothermal power plant;
receiving, at the receiver, second brine conditions sensed at a second part of the geothermal power plant;
determining, at a first circuit, a first analyte value according to the first sensed brine conditions;
determining, at the first circuit, a second analyte value according to the second sensed brine conditions;
determining, at a second circuit, a first product dosage value for a first product according the first analyte value and product information, the first product dosage value being an amount of the first product suggested to adequately prevent buildup, corrosion, or a combination thereof at the first part of the power plant, according to historical power plant data; and
determining, at the second circuit, a second product dosage value for a second product according the second analyte value and the product information, the second product dosage value being an amount of the second product suggested to adequately prevent buildup, corrosion, or a combination thereof at the second part of the power plant, according to the historical power plant data.

2. The method of claim 1 , further comprising: displaying, at a display device, the first and the second product dosage values along with graphical representations of the first and the second parts of the power plant.

3. The method of claim 1 , wherein the first part is a head of a first production well and the second part is a head of a second production well.

4. The method of claim 1 , wherein the first part is a head of a production well and the second part is a head of a brine mixing tank, a head of a flash tank, a head of a geothermal fluid pipe in a binary system, or a head of a working fluid pipe in the binary system.

5. The method of claim 1 , wherein the first product and the second product are similar products.

6. The method of claim 1 , wherein the first brine conditions and the second brine conditions include brine temperature, brine pressure, brine contents, or any combination thereof.

7. The method of claim 1 , wherein the first analyte value and the second analyte value are representative of concentrations of one or more minerals, molecules, materials, or any combination thereof.

8. The method of claim 1 , wherein the first product and the second product include a calcite inhibitor, an anhydrite inhibitor, a silica inhibitor, a fluorite inhibitor, any other type of mineral inhibitor, a biocide, a corrosion inhibitor, or any combination thereof.
