✦ Synopsis

When a non-reactive compressible gas experiences a considerable pressure drop during flow, such as in gas production from petroleum reservoirs, compressibility effects have to be added to the treatment of material dispersion of incompressible systems. In this paper, the dispersion resulting from such effects is calculated and expressed in terms of a Transfer Function with the Dispersion Number as parameter. It is shown that the effect of compressibility is considerable, particularly for large pressure gradients. The analysis is limited to an ideal gas in isothermal flow with a continuous velocity distribution (i.e. no sonic velocity) and flow through a porous mass or fixed bed which can be represented by the axially dispersed flow model.
