Resumen de: US2025216124A1
Closed loop hydronic systems, devices and methods to control a temperature of a petroleum are described herein. The closed loop hydronic systems use a body of water as a heat sink and, optionally, a heat source to control a temperature of the petroleum. The systems include at least one heat exchanger positioned within the body of water. Water is pumped through pipes connected to the heat exchanger(s) to a surface where a vessel, such as but not limited to a transfer pipe or a storage tank, holding the petroleum is present. In one example, the systems may provide a heat sink to cool petroleum in tanks during extreme hot weather conditions. In another example, the systems may provide a heat source to warm marine fuel in tanks during extreme cold weather conditions.

Systems and methods using fluid flow through concentric channels for ground heat exchange. A heat exchange system may be installed by inflating a flexible tube in a borehole. An accessible subsurface adaptor provides connections between the heat exchange features and laterals, as well as the ability to measure and monitor performance of the system.

A geothermal energy system, having a carbon dioxide store at a first temperature and density, a retrieving device for retrieving carbon dioxide at a second temperature higher than the first temperature and a second density lower than the first density, a heat pump having a first heat exchanger, a compressor, a second heat exchanger, and an expander or a throttle. The first heat exchanger transmits thermal energy of the carbon dioxide to a process medium of the heat pump. The compressor compresses the process medium downstream of the first heat exchanger. The second heat exchanger transmits thermal energy of the compressed process medium to a consumer, and the expander or the throttle expands the process medium downstream of the second heat exchanger, and an introduction device introduces carbon dioxide downstream of the retrieving device and upstream of the heat pump into the system.
Resumen de: WO2024044251A1
Methods for forming pathways of increased thermal conductivity in a geothermal well are disclosed. The pathways increase heat transfer efficiency in a closed loop geothermal operation. The methods comprise injecting a thermally conductive material into the annular space between a conduit in the wellbore and the formation; forming a fracture in the formation and filling it with the thermally conductive material; and putting the well in an underbalanced state and drawing the thermally conductive material back towards a port in the conduit that is in an excluded configuration to create a pathway of increased thermal conductivity. The thermally conductive material may comprise a fluid carrier and solid particles having a high thermal conductivity.

A heat exchanger 5 is disclosed for the lower end of a pipe (3, fig 1) disposed in a geothermal well bore (2, fig 1). The heat exchanger includes one or more vanes 19 arranged to cause a working fluid exiting the lower end of the pipe to return up the geothermal well bore via a helical path 22 between an outer radius of the pipe and an interior radius of the geothermal well bore. The helical path having a pitch length (P, fig 4B) and a total length (H) parallel to the geothermal well bore. A thermosiphon (1, fig 1) connected to a turbine (9, fig 1) and comprising the heat exchanger is also claimed. A method of coupling the heat exchanger to a pipe and lowering it into a geothermal well bore is also claimed. Use of the heat exchanger or thermosiphon in generation of electricity is also claimed.
