ABSTRACT:
The invention is a method of returning process generated warm vapors of a cryogen such as hydrogen, helium and neon, to the main liquefier by contacting the warm vapors with process liquefied cryogen in order to generate saturated, essentially constant enthalpy vapors that can be readily processed by the main liquefier. Three example methods are described. In the first two methods, the warm vapor is recycled through the main storage tank associated with the process back to the main liquefier. In the third method, the warm vapor is washed with liquid in a contactor before being recycled to the main liquefier.
