Title: Manuel E. Obando: Innovating Geothermal Solutions

Introduction

Manuel E. Obando, an accomplished inventor based in Whittier, California, is recognized for his contributions to geothermal technology. With a total of three patents, his innovative approaches have paved the way for more effective and environmentally friendly methods of utilizing geothermal energy.

Latest Patents

One of Obando's latest patents focuses on a method to treat geothermal fluid streams. This integrated system combines non-condensable gas (NCG) and condensate treatment, allowing for the effective handling of geothermal power plant condensate and non-condensable gas effluent streams that contain hydrogen sulfide (H₂S) and ammonia. This technology not only enhances the commercial value of the emitted streams but also fosters their use in agricultural settings. By adjusting the pH of the condensate and scrubbing the H₂S from the NCG, the method provides a pathway for enriching the ammonia content for use as fertilizer or irrigation water. Additionally, the system emphasizes a nearly total elimination of emissions from geothermal operations, marking a significant step forward in environmental sustainability.

Another notable patent addresses the control of salt precipitation from geothermal brine. This invention involves diluting a brine concentrate produced from geothermal resources using preconditioned condensate. By adjusting the pH and reducing sulfide ion concentration through oxidation, the resultant injection stream is optimized for underground injection, thus enhancing resource recovery while minimizing waste.
