GAS SPARGER HEAD FOR AIRLIFT GEOTHERMAL SYSTEMS

Resumen de: US20260146517A1

0000 Various examples are provided related to airlift pumping of downhole geothermal fluids. In one example, an airlift system includes a compressor; a gas sparger head in a wellbore of a geothermal well, and a pressure head recycle assembly. The sparger head produces artificial lift of the geothermal fluids by injecting a gas resulting in a difference in density downhole. The entrained gas can be extracted by the pressure head recycle assembly, compressed, and reinjected downhole. The geothermal fluid at the well head can be used in direct use applications or in a thermodynamic cycle to make shaft power. The gas sparger head can include a venturi shaped passage extending through the gas sparger head and a bubble orifice including gas orifices radially spaced about a narrow portion of the venturi shaped passage. The gas orifices can have a corresponding resonant chamber through which the gas (e.g., air) is provided.

PROCESS COOLING ROD

Resumen de: EP4749231A2

A process heat exchange rod for cooling or heating liquids in a process vessel. The rod may have a linear form and extend downward through an upper wall of the process vessel into proximity with the lower floor. The rod internally defines a circulatory flow path for the heat exchange medium, including an outer jacket and a flow diverter having a central through bore and external helical flutes. Heat exchange medium travels down through the central through bore and then back up through helical grooves formed between the flow diverter and the outer jacket, or vice versa. Accurate heating or cooling of the process fluid is attained by modification of the configuration of the heat exchange rod as well as the flow rate and temperature of the heat exchange medium. The components may be injection molded of a polymer, often transparent, having a high heat transfer coefficient.
