Active magnetic regenerative liquefier using process gas pre-cooling from bypass flow of heat transfer fluid
Abstract
A process for liquefying a process gas that includes: introducing a heat transfer fluid into an active magnetic regenerative refrigerator apparatus that includes a low magnetic or demagnetized field section; continuously diverting a bypass portion of the heat transfer fluid from a cold side of the low magnetic or demagnetized field section into a bypass flow heat exchanger at a first cold inlet temperature; and continuously introducing the process gas into the bypass flow heat exchanger at a first hot inlet temperature and discharging the process gas or liquid from the bypass flow heat exchanger at a first cold exit temperature; wherein the temperature difference between bypass heat transfer first cold inlet temperature and the process gas first cold exit temperature is 1 to 5 K.
