Abstract: A heat pump has an internal heat-absorbing section that receives heat and an internal heat-releasing section that releases heat. Heat is transferred between the internal heat-absorbing section and the internal heat-releasing section using a magnetic particle dispersion circulating between the internal heat-absorbing section and the internal heat-releasing section. The heat pump may include: an external heat-absorbing section in which a secondary working fluid receives heat from a heat-giving fluid; an external heat-releasing section in which the secondary working fluid releases heat to a heat-receiving fluid; and a circulation channel that allows the secondary working fluid to circulate.

Abstract: To provide a process for separating hydrocarbons capable of recovering ethane or propane, including improved cold heat recovery enabling a reduction in compressor power. A process for separating hydrocarbons, in which a residual gas enriched with methane or ethane and a heavy fraction enriched with a lower volatile hydrocarbon are separated, includes: a) partially condensing the feed gas by cooling using the residual gas and another refrigerant as a refrigerant, followed by vapor-liquid separation; b) depressurizing and supplying the liquid obtained from step (a) to the distillation column; c) expanding a part or all of the gas obtained from step (a) by an expander to cause partial condensation, followed by vapor-liquid separation; d) feeding the liquid obtained from step (c) to the distillation column after using it as the further refrigerant in step (a); e) feeding a part or all of the gas obtained from step (c) to the distillation column; and f) obtaining the residual gas from the top of the distillation column and the heavy fraction from the bottom of the distillation column.
