Mopoz N. NOx absorption by cavitation with gas-liquid flow redistribution in the nitric acid technology absorption column

The object of research: the processing of acidify in technology nitric acid. The aim of research: improvement technology of reprocessing oxide nitrogen in nitric acid the grounds of analysis regularity of behavior in liquid phase, including using of the hydrodynamic cavitations' effects. Method of testing: Analysis: complex of the modern methods theoretical and experimental researches was using. Chemical analysis liquid and gas phases were transmitting by titrimetric method. Analysis of physics and chemic characteristic cavitation water has transacted with helping of analyzer WATER TEST. Researching of acidify process was transmitting with using of the special producing experimental installation of absorption column and cavitation. Theoretical and practical results: The reasons of diminution of ruinous strength connecting with using of solvates (HNO3nNOx) and hydrates (HNO3nH2O) in a range of concentration HNO3 from 10-40% mass. have formed. Creasing methods of diminution of ruinous strength in process of acidify by redistribution gas-liquid currents have proposed and researched experimentally. The theoretical conditions of the positive influences of cavitation aqueous solution HNO3 for the property solution and for process of acidify and for the proposing mechanism of this process have certificated experimentally. The technological circuitry of redistribution gas-liquid currents previous cavitation of watering process have proposed with receiving results, it gives to absorption allowing to raise the degree of processing and provides concentration NOx after absorbtion 0,03% instead 0,11 for now. Innovation: An analyzes theoretically and practically made by researching of influence effect hydrodynamic cavitations' for absorption quality water and gas-liquid's redistribution currents have made with preparatory cavitation condition liquid phase. Introduction: The technical decision made and it improved on the enterprise CC "Severodonetsk obyednannya "Azot" with economic effect of 2,3 mill.grn. Using field: applied chemistry (chemical engineering)
