  • Patent number: 11353261
    Abstract: Light gases such as helium are extracted from a carbon dioxide-containing feed stream by distillation. Costly dehydration steps are avoided by pumping the liquid bottoms stream leaving the distillation column without vaporization so as to ensure that any water present in the feed remains in solution with the bulk stream leaving the process. This prevents any liquid phase water causing corrosion or solid ice or hydrates forming to plug the flow.

  • Patent number: 11340000
    Abstract: A method for controlling a vapour compression system (1) is disclosed. A mass flow of refrigerant along a part of the refrigerant path is estimated, based on measurements performed by one or more pressure sensors (10, 12, 13) for measuring a refrigerant pressure at selected positions along the refrigerant path and one or more temperature sensors (11, 14) for measuring a refrigerant temperature at selected positions along the refrigerant path. A refrigerant pressure or a refrigerant temperature at a selected position a pressure sensor (10, 12, 13) or temperature sensor (11, 14) along the refrigerant path is derived, based on the estimated mass flow. The vapour compression system (1) is allowed to continue operating, even if a sensor (10, 11, 12, 13, 14) is malfunctioning or unreliable.

  • Patent number: 11340021
    Abstract: A heat exchanger module includes a condenser unit and an evaporator unit. The evaporator unit includes N pieces of parallel-flow heat exchangers arranged adjacently, and the coolant temperatures reduce gradually from the first to Nth parallel-flow heat exchangers along an air flow direction in the evaporator unit. A counter-current mounting method is adopted in the parallel-flow heat exchangers of the evaporator unit in the heat exchanger module provided by the present invention. The coolant temperature of each parallel-flow heat exchanger is lower than that of the previous one, the temperature difference between air and coolant is relatively uniform by using the counter-current method so as to reach a better heat exchange effect.
