Abstract
A heat exchanger or regenerator system useable in an air separation plant to minimize infiltration of air into the low pressure nitrogen stream comprising a heat exchanger (regenerator) having at least one flow path for the reversing heat exchange fluids, which flow path has at each end, an inlet branch and an outlet branch, wherein each branch has two series connected valves with a vent pipe between each pair of valves. Fluid flow through the vent pipe is controlled, e.g. by remotely actuable switch valves.
