Is the chemical process flow the same as the equipment flow?

The chemical process flow chart is different from the equipment flow chart. The main function of process flow chart is to show the processing flow of workpiece, and the equipment flow chart refers to the equipment flow of workpiece processing, from one equipment to another. Process flow chart is a design document used to express the chemical production process. It mainly includes scheme flow chart, material flow chart, construction flow chart (process flow chart with control points) and scheme flow chart, which express the process flow of materials from raw materials to finished products or semi-finished products, as well as the equipment and machines used. It is used to discuss the process plan at the beginning of design and can also be used as the design basis of construction flow chart. On the basis of the scheme flow chart, the material flow chart and the material flow chart adopt the form of combining graphics and tables. Drawings reflecting the results of material balance and heat balance in design, and construction flow chart (process flow chart with control points) are the basis for designing and drawing equipment layout and pipeline layout, and are also the main reference for construction, installation and production operation. The equipment flow chart is a system diagram that uses graphic symbols to represent the equipment used in each production operation of coal preparation plant and their interrelationships.
