Question 1 Sulfuric acid is acting as important additives in a lot of pharmaceutical production processes. It is also used to dry chemicals in dozens chemical processes. Various technologies are available to produce sulfuric acid. The contact process is the most popular one where sulfuric acid is produced in three main steps: (1) production of sulfur dioxide SO2, (2) oxidation of SO2 to sulfur trioxide SOs, and (3) absorption of So; in water to form sulfuric acid. The following reactions occur during the production of sulfuric acid: S + O2 SO2 SO2 + 1202 SO SO, + H2O H2SO4 a. For this process, generate a process concept diagram. b. Develop a preliminary block flow and process flow diagram for this process. c. Provide two alternatives for sulfuric acid process. For each alternative, show both BFD and PFD
