A block diagram is a diagram of a system where the principal parts or functions are represented by blocks connected by lines that shows the relationships of the blocks. A chemistry block diagram displays a structural representation of a system as it gives a quick overview of the working process from how the data is retrieved and how the desired result is achieved. As the chemistry block diagram shows, solvents, and raw materials mix together where the waste gas from scrubbing is released after the reaction. Meanwhile, from the distillation and concentration process, wastewater is also discharged. Instead of creating a block diagram explaining a chemical cycle from scratch, use EdrawMax as it provides several shapes and figures that let you create some amazing block diagrams.
