Title: D Stephen Pye: Innovator in Geothermal Energy Solutions
Introduction
D Stephen Pye is a notable inventor based in Brea, CA, who has made significant contributions to the field of geothermal energy. With a total of 2 patents, his work focuses on innovative methods for harnessing geothermal resources while ensuring environmental safety.
Latest Patents
One of his latest patents is a method for the production of usable steam and non-toxic solids from geothermal brine. This method allows for the generation of electric power from hot, pressurized geothermal brine that contains dissolved toxic elements. The process minimizes the precipitation of toxic solids and produces non-toxic solids that can be disposed of or utilized in an environmentally acceptable manner. The method involves removing geothermal brine from an underground aquifer, separating non-condensable gases, and establishing an air-free flashed brine handling system. The steam derived from the brine is then used to produce electric power, with the condensate being air-cooled and reused in the process.
Another significant patent by Pye is related to foam drilling using a di-substituted taurate foaming agent. This method is particularly useful for conducting foam drilling and workover operations in high-temperature formations, such as geothermal sites. The aqueous solution of a N-acyl-N-methyltaurate foaming agent enhances the efficiency of drilling operations in challenging subterranean environments.
