| Abstract: | Based on analysis on the shortages and problems found in traditional bubble-cap tray column, Sichuan Lutianhua Co., Ltd have developed spiral type of column for concentrated nitric acid bleaching. By employing this column in nitric acid plant, the process of nitric acid producing is improved, which reduces the maintenance, realizes the purpose reducing the energy consumption, prolongs the running life of the plant with direct synthesis process. |
