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.
Claims5
A reversible heat exchanger or regenerator system comprising a heat exchanger or 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 is provided with two valves arranged in series, a vent pipe in communication with the branch between the two valves and means for controlling the flow of fluid through said vent pipe.
