  • Patent number: 11906248
    Abstract: A method of heating a fluid stream for a power plant comprises diverting a portion of a main flow of flue gas from a power plant at a first pressure (P1), flowing the diverted flue gas through a heat exchanger, flowing an auxiliary fluid stream through the heat exchanger, and transferring heat from the diverted flue gas into the auxiliary fluid stream in the heat exchanger to raise a temperature of the auxiliary fluid stream from a first temperature (T3) to a second temperature (T4), while lowering a first temperature of the diverted flue gas (T1) to a second temperature (T2). The diverted flue gas is then returned to the main flow of flue gas in the power plant at a second pressure (P2). The method of flue gas flow through the heat exchanger may be accomplished by adding a self-contained flow path from a boiler higher pressure (P1) zone to a lower pressure (P2) zone.

  • Patent number: 11242785
    Abstract: Provided is a process that may comprise cooling an engine exhaust emissions comprising SOx on a vehicle that may come from an engine. The cooled engine exhaust emissions comprising SOx may be passed to one or more absorption units. The SOx may be extracted from the engine exhaust emissions with a sorbent supported on solid porous media in an absorption unit on the vehicle to form an absorbed SOx. The absorbed SOx may be desorbed, followed by forming one or more SOx product from the desorbed SOx. The one or more SOx product may be unloaded to an off-vehicle facility.

  • Patent number: 11180702
    Abstract: The present development is a metal particle coated nanowire catalyst for use in the hydrodesulfurization of fuels and a process for the production of the catalyst. The catalyst comprises titanium(IV) oxide nanowires wherein the nanowires are produced by exposure of a TiO2—KOH paste to microwave radiation. Metal particles selected from the group consisting of molybdenum, nickel, cobalt, tungsten, or a combination thereof, are impregnated on the metal oxide nanowire surface. The metal impregnated nanowires are sulfided to produce catalytically-active metal particles on the surface of the nanowires The catalysts of the present invention are intended for use in the removal of thiophenic sulfur from liquid fuels through a hydrodesulfurization (HDS) process in a fixed bed reactor. The presence of nanowires improves the HDS activity and reduces the sintering effect, therefore, the sulfur removal efficiency increases.
