Abstract
Purpose: Study of the possibility of reducing the energy intensity of adsorption processes with high requirements for the moisture content of compressed air. Results: It has been shown that the molecular sieve RS-144M has the lowest weight among all the adsorbents represented due to its low density, which makes it possible to reduce the weight of the adsorption unit; the smallest volume and height of adsorption filling in the column have zeolites NaA and Ka-CO, followed by molecular sieves; due to the release of the molecular sieve RS-144M in the form of a powder the size of the working pores of 3Å, it has a low bulk density and the smallest intergranular spaces, which provides a low value of porosity of the granules, a total of 8.3% of the total fill volume. Practical significance: The use of molecular sieves produced on the basis of zeolite helps to reduce the energy capacity of the compressed air drying process. The most effective is the molecular sieve RS-144M. It allows you to dry compressed air to meet the requirements of the highest moisture purity classes, while guaranteeing the lowest energy consumption. The remaining adsorbents will also allow the compressed air to be dried to the desired purity grade, but will have an energy consumption greater than that of the RS-144M, making their use not always expedient.
