Abstract: Mathematical methods are developed to describe helium sorption by microspheres with a certain dispersion distribution. An analytical solution of the problem is derived and applied to expand the experimental dependences of the degree of helium absorption by microspheres on time into harmonics. As a result, the time characteristics of the sorption process can be analyzed.

Keywords: helium, natural gas, microspheres, separation, mathematical simulation, harmonics, ordinary differential equations, matrix exponent.
