Chemical process drawing The chemical process diagram includes process flow chart, chemical process diagram, including process flow chart, equipment layout and piping layout. This chapter introduces the process flow chart. And piping layout, this chapter introduces the process flow chart. A process flow diagram is a diagram for expressing the flow order of material and the sequence of operations in the process of production. A pattern of flow order and order of production operations. The design process of chemical process flow chart can be divided into three stages as follows: three stages: the production process of the production process in the production process of sketch; sketch; production process. Production process flow chart. 1.1 classification of process flow chart 1.1 classification of process flow chart total process flow chart Also known as plant material balance, also known as the material balance chart, used to express all the production units (or workshop section) unit (or workshop section) flow path and material balance between the main logistics results. Material balance result. Two material flow chart Also called program flow chart, also known as programme flow chart, is the basis of the total process flow diagram, which expresses the process and material flow of each workshop. The design of each process and material flow in each workshop. Three. Process flow chart with control points (PID diagram) Production control flow chart or the construction process flow chart and control flow chart of construction or production process flow chart, which is based on the material flow chart on the basis of the material flow chart on the basis of a process flow diagram detailed content. Flowchart. 1.2 drawing requirements of process flow chart Production process sketch The general drawing
