Material balance of nitrogen and sulfur components in simulated flue gas treated by an electron beam

Abstract

The material balance of nitrogen and sulfur components in simulated flue gas (NOSO 2H 2OO 2NH 3N 2) treated by an electron beam was measured using 15N labeled NO (250 ppm). Combinations of chemical analysis, instrumental analysis and mass analysis were used to identify and quantify the nitrogen-containing products as well as to determine the ratio of 15N in each product. The products 15N 14N, 15NO 3 −, 15NO 2, 15N 14NO and 15N 15NO were detected after electron beam treatment of the gas. Perfect material balance of 15N (103%) was obtained. The material balance of the sulfur components was measured using two different chemical analysis methods. All the removed SO 2 was converted to SO 4 2− by electron beam treatment, and both methods yielded a satisfactory balance (103 and 105%).
