4; below this temperature the k 12 values decrease uniformly toward zero at the lowest temperatures. 4 reproduces the experimental B 12 values satisfactorily. Based on the observed temperature dependence of the k 12 values and the difficulty in making phase-equilibria measurements with ethane, particularly in the low-temperature region, it is possible that the data presented here for the helium-ethane system might inelude a consistent, temperature-dependent error due to some undetected phenomenon, such as adsorption in the higher temperature regions of the apparatus.

Individual points are shown for the nitrogen curves, since the nitrogen analysis was made on agas chromatograph equipped with a thermal conductivity detector, and consequently the analysis had to be done on a sampie by sampie basis rather than continuously. The methane concentrations, on the other hand, were measured continuously on a strip chart recorder and as a result no individual points are shown.

Dickson NBS Institute fOT Basic Standards Boulder, Colorado INTRODUCTION Adsorptive purifiers are fixed-bed units in which the carrier gas containing the impurity to be adsorbed is passed through a packed bed of adsorbent. In this type of operation there are two distinct mass transfer processes : the diffusion of the impurity through the gas phase to the surface of the adsorbent, and diffusion into the particle.
