Design Analysis for 330 kt/a Sulfur-based Sulfuric Acid Plant

The 330 kt/a (Yunnan) is another modern and large sulfur based sulfuric acid plant developed and designed by Nanjing Chemical Industrial (Group) Design Institute. The process flow and technical features of the plant is introduced and it is indicated that new equipment and new materials are used in the plant. Central tube type stainless steel converter, low dry absorption column and turbine driven primary blower are synchronously used for the first time among large domestic sulfur based sulfuric acid plants.
