Estimating the term…
A process and apparatus for recovering at least nitrogen, oxygen and/or argon from a feed gas (e.g. air, process gas stream, etc.) can be configured to provide an improvement in operational efficiency with reduced electricity costs. Some embodiments can be adapted so that a substantially liquid feed can be fed for continuous separation processing while liquefaction of the feed may only occur intermittently during low electricity rate time periods. Some embodiments can utilize at least one tank for storage of the liquid feed received from a liquefaction processing unit for storage and use of the liquid feed for the continuous operation of the separation unit(s) utilized for separating desired product outputs from the liquified feed stored in the one or more tanks. The at least one tank can be a single tank or more than one tank (e.g. at least two tanks).
