Division of Operations Research internal report

"The Division of Operations Research has instituted a program to obtain phase equilibria data for helium-bearing natural gases which are of special interest to the Helium Activity. This plan encompasses the studies of gas processed for helium by our operating plants in addition to gases which give promise of becoming the source material for prospective plants. The actual study is performed on gas from which carbon dioxide, water, and hydrogen sulfide have been removed so that the experimental apparatus will not be plugged with solids which otherwise would form at the low temperatures encountered...The present report is a phase study related to the gas from which helium is extracted at the Excell Helium Plant"--Page 1.
