Algebraic Method for Concentrated Gases

Algebraic Method for Concentrated Gases When the feed gas is concentrated, the absorption factor, which is defined in general as A = Lm/KGm and where K = t/°/x, can vary throughout the tower due to changes in temperature and composition. An approximate solution to this problem can be obtained by substituting the effective adsorption factors A, and A derived by Edmister [Ind. Eng. Chem. 35, 837 (1943)] into the equation 

This procedure has been applied to the absorption of C5 and lighter hydrocarbon vapors into a lean oil, for example.

In diffusion combustion of unmixed gases the combustion intensity is limited by the supply of fuel and oxidizer to the reaction zone. The basic task of a theory of diffusion combustion is the determination of the location of the reaction zone and of the flow of fuel and oxidizer into it for a given gas flow field. Following V. A. Schvab, Ya.B. considered (22) the diffusion equation for an appropriately selected linear combination of fuel and oxidizer concentrations such that the chemical reaction rate is excluded from the equation, so that it may be solved throughout the desired region. The location of the reaction zone and the combustion intensity are determined using simple algebraic relations. This convenient method, which is universally used for calculations of diffusion flames, has been named the Schvab-Zeldovich method.
