| Abstract: | Technical features of high concentration of SO2 pre-conversion process are introduced in the aspects of pre-conversion process, SO3 circulation process and isothermal conversion. Jinchuan Co. adopted pre-eonversion process and double absorption process in 1 600 kt/a sulphuric acid plant based on copper smelter off-gas and used low-temperature heat recovery technology in drying and absorption section, with 18 vol% SO2 in flue gas entering converter, total conversion of 99.94% and steam production of 1.0 t/t. |
