The authors have solved scientific and technical problems of mathematical modeling and calculation of thermal efficiency, and also of structural characteristics of packed scrubbers of condensation water cooling of a gas in a film countercurrent regime. By simultaneous solution of the heat-balance equation and the expressions for thermal efficiencies of a packed scrubber in the gas and liquid phases, a relation has been established between the thermal efficiencies of condensation cooling of the gas and heating of the water. With an assigned temperature regime of cooling of the gas and its thermodynamic state, a required gas-phase thermal efficiency is computed. To calculate the actual thermal efficiency of a packed bed, use is made of a cellular model of the flow structure in the liquid and gas phases. An expression has been obtained for calculating the height of the packed bed from the assigned thermal efficiency, structural characteristics of the packing, and flow rates of the gas and water. Agreement with the existing experimental data has been shown and a calculation algorithm has been given. Conclusions on the most efficient packing structures have been drawn.
