Abstract

The article concerns the mathematical model of heat-exchange process of the separation part of condensation column of the unit of secondary condensation of synthetic ammonia. The experimental data on condensation column were obtained in industrial conditions according to the method of passive registration experiment. The influence of material flow on the temperature regime of circulation gas after separation was analyzed, and the equation for calculating the temperature, necessary to determine the heat-exchange surface of the column, was derived. The dependence was determined, using the package Statistica, calculation error does not exceed 5%. The set temperature indicates that it is lower than that adopted for the project. The specified temperature provides an increase of the average logarithmic temperature difference, and, for the same heat load the decrease of the heat-exchange surface, and consequently, the reduction of the specific quantity of metal of the condensation column in general.
