ABSTRACT:
An improved process and apparatus is disclosed for rejecting nitrogen from a gaseous nitrogen-methane mixture while the nitrogen content of the mixture varies widely. The process, which is especially suited for recovery of nitrogen in an enhanced oil reservoir flooding project which employs nitrogen for flooding the reservoir; utilizes a modified dual distillation column arrangement including a relatively high pressure fractionator which lacks a conventional reboiler and a low pressure fractionator which lacks a conventional overhead condenser for liquid reflux.
