| Abstract: | In this paper, a new process has been suggested for treating NO_x waste gas. This process consists of following steps: 1) absorbing nitrogen oxide with pyrolusite, 2) purification and concentration of the solution from absorbing step, 3) crystallizing of Mn(NO_3)_2 from the concentrated solution, 4) preparation of pure MnO_2 by heat decomposition of Mn(NO_3)_2, 5) production of nitric acid by absorbing NO_x from the heat decomposition step with water etc. The test results indicate the process is feasible technically, and has significant environmental and economic benefits. |
