Оптимизация технологического процесса отбелки концентрированной азотной кислоты путем применения фторопластовых тепломассообменных аппаратов

Abstract

In work are investigated and the factors of influence of fiuoroplastic heat and mass exchange devices on process desorption of oxides of nitrogen in manufacture of concentration a nitric acid by a direct method are described. The mathematical dependences allowing to predict realization of process desorption of oxides of nitrogen and his optimum conditions depending on major factors of a technological mode are given. The opportunity of the operative equation by a temperature mode of bleach a column in the strictly given parameters is achieved, that is absent in a typical design aluminium bleach of columns.
