This detailed process flow diagram represents an industrial chemical processing system. It outlines the flow of materials through various stages of processing, including the introduction of 'Aire humedo' (humid air) and two concentrations of sulfuric acid (H2SO4 at 98% and 67%). Valves and flow directions are indicated with numbered markers, suggesting controlled steps in the process. It is a vital tool for engineers, operators, and technicians in the chemical industry, ensuring precise control and safety in the plant.
