Abstract
Methods and apparatus for magnetically cooling and liquefying a process stream include a plurality of active magnetic regenerative refrigerators (AMRRs) configured in parallel or in series and parallel. Active magnetic regenerative liquefiers (AMRLs) include such AMRRs and are configured to liquefy, for example, natural gas or hydrogen. In specific embodiments, a magnetic field is produced by hexagonally arrayed solenoids and magnetic refrigerants are selected to provide a thermal mass that is dependent on an applied magnetic field.
