Abstract
A new graphical method for solving enthalpy transfer problems is described in which a modified enthalpy is the transfer potential. The condition line is determined by successive approximations. An entire condition line is constructed for each approximation, and the resulting approximate line determines an auxiliary line used for the next construction. The method was used to calculate enthalpy transfer coefficients from experimental data on enthalpy transfer in a grid-packed tower for the tetrachloroethylene-air system, which are reported. Three types of countercurrent operations were studied: 1. The vapour content of the gas is increased and the gas is heated by hot liquid. 2. The vapour content of the gas is increased and both the gas and the liquid are cooled. 3. The liquid is heated by the hot gas and the vapour content of the gas is either increased or decreased. The enthalpy transfer coefficients for operations of the first type were lower than those for the other two. The existence of fog during dehumidification had no apparent effect on the coefficients. The application of the graphical method to the design of a cooler-condenser is described.
