Húni SIGHVATSSON has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20230211283
    Abstract: An improved system for separating gas from a process stream by providing a stripping unit at the overhead stream of a fractionation column to selectively and effectively remove the gas using a stripping fluid without providing a dedicated light-ends separations unit. The stripper unit may be connected to the reflux drum at the overhead stream. The system for separating gas further achieves greater thermodynamic efficiency by means of a split column design using mechanical vapor recompression with the reboiler and condenser integrated in a falling-film evaporator- or thermosiphon-type vapo-condenser.

  • Publication number: 20220219112
    Abstract: This invention relates to a method and a system of abating carbon dioxide (CO2) and/or hydrogen sulfide (H2S) in a geological reservoir. Water is pumped or transferred from a water source to an injection well. The gasses are merged with the water under conditions where the hydraulic pressure of the water is less than the pressure of CO2 and/or H2S gas at the merging point. The water with CO2 and/or H2S gas bubbles is transferred further downwardly at a certain velocity higher than the upward flow velocity of said CO2 and/or H2S gas bubbles ensuring downward movement of gas bubbles resulting in full dissolution of said CO2 and/or H2S in the water due to elevating pressure. The complete dissolution ensures a lowered pH of the water entering a geological (e.g.
