Sg. Dyakonov et al., MODELING OF SEPARATION PROCESSES ON CONTACT DEVICES IN INDUSTRIAL COLUMNS, Russian journal of applied chemistry, 66(1), 1993, pp. 77-89
This paper surveys publications on the physical and mathematical model
ing of mass and heat transfer, flow structure, and efficiency for bubb
le-cap contact devices in column-type equipment. It is concluded that
existing approaches to modeling lack a quantitative foundation linking
fundamental and specialized knowledge. Bypassing multiple experimenta
l studies in the design of industrial systems requires that fundamenta
l knowledge in the form of conservation and equilibrium laws be used f
or modeling. A new approach to modeling of separation processes on con
tact devices is discussed; it only provides for experimentation with a
laboratory prototype. The mathematical description structure is selec
ted in this stage, and the parameters of the resultant model are found
during scaleup, utilizing the variational formulation of the momentum
, mass, and energy conservation laws.
