PCT No. PCT/SE95/01122 Sec. 371 Date Aug. 15, 1996 Sec. 102(e) Date Aug. 15, 1996 PCT Filed Oct. 3, 1995 PCT Pub. No. WO96/11876 PCT Pub. Date Apr. 25, 1996A new chemical reaction container (43) is provided which is suitable for a process plant the production of sulfuric acid according to the contact process. It comprises a cylindrical envelope surface and is divided by vertical separation walls into at least two sections, usually three. Each section has an inlet and an outlet, the separation walls at their bottom parts having one or several openings for making contact possible between the different sections. The advantage of this is that both the drying of the process gas, the interpass absorption step and the final absorption step may be conducted in one and the same reactor, instead of three separate reactors, as done previously. This saves both space and material. Further are provided a plant and a process for the production of sulfuric acid according to the contact process, which plant and which process comprise the above reactor container. |
