MODERNIZATION OF PLANT FOR THE ORGANIZATION OF MANUFACTURE OF LIQUID CARBON DIOXIDE ACCORDING TO THE EUROPEAN STANDARDS

Abstract

The high demands make to lowtemperature carbon dioxide according to the European standards. The analysis of made product by refrigerating carbon dioxide plant has shown that the basic undesirable impurity in ready CO2 is CO. By researches it is established that the maintenance of CO can achieve 17 ppm. Two ways of decrease of CO in lowtemperature liquid CO2 are considered. One of them is based on use of additives O2 in compressed CO2 and the further oxidation of CO and H2 in a reactor on rutheniumpalladium catalyst up to CO2 and H2O. The second way taken for basis for introduction, provides inclusion in the technological circuit of plant a steaming columns for reliable and thin clearing of CO from CO and other solute gases.
