Experimental determination of the coefficient of gas permeability of a porous binder of composite sorbent

摘要

Helium is an important substance for modern industry. The actual task is the development of effective methods for extracting helium. The membrane-sorption method, based on selective permeability of microspherical membranes (microspheres) to helium, stands out among such method. In this paper, an experimental determination of the permeability coefficient for the binder material of granules of a composite sorbent based on MS-VP-A9 5 group microspheres had been carried out. The experiments had been conducted for air and helium. The air permeability coefficient value was about 16.71 ± 11.70 darcy.
