Design a Nitrogen Removal Unit (NRU) with Helium Recovery using a double-column cycle to process 50 MMSCFD of pipeline gas at 800 psig. The process natural gas must be delivered to the pipeline at 1,000 psig containing no more than 2% Nitrogen. The crude He product must contain at least 65% He with a recovery of 96% of the He in the feed. As part of the design optimize energy usage by adjusting the column pressures to minimize the power input and by evaluating the use of turbo-expanders versus Joule-Thompson valves.
