Part 9: Use EdrawMax for Easy Process Flow Diagram Creation EdrawMax provides an extensive range of symbol libraries. These libraries are compatible with most mechanical and industrial requirements in piping, instrumentation, and all the required processes. Use Process Flow Diagram Symbols Now A Pro...
This chapter covers different types of chemical process diagrams, how these diagrams represent different scales of process views, one consistent method for drawing process flow diagrams, the information to be included in a process flow diagram, and the p
Use the standard symbol of the equipment, sketch, etc, set by the project standard. It should be represented in the legend sheet. Use the applicable data in a tabulated format and show it at the bottom of the process flow diagram for each unit operation and process line. Define the steam...

The chemical processing industry has as- signed a symbol for each type of valve, pump, compressor, steam turbine, heat exchanger, cooling tower, basic instrumentation, reactor, distillation column, furnace, and boiler (Figure 12.1). There are symbols to represent major and minor process lines ...
6) Arrows may be used on process lines to indicate direction of flow. 7) Symbols should be shown only when they are important to understanding the operation or are an integral part of the process depicted. Symbol qualities, such as luminance, size, color, fill, and contrast should be ...
Knowing and recognizing these symbols is important for a new technician.The chemical processing industry has as- signed a symbol for each type of valve, pump, compressor, steam turbine, heat exchanger, cooling tower, basic instrumentation, reactor, distillation column, furnace, and boiler (Figure ...
Non-flow parameters, although not used for heat exchangers, are included for completeness. Table 3.1. Availability and Exergy terms NameNonflowflow SymbolEquation (intensive form)SymbolEquation (intensive form) Availability A,a a=e−T∘s+p∘v B,b b = ht-ToS Exergy (thermomechanical or ...
To start tuning Smart Bass, enable Smart Bass and click the Expand symbol, as shown in the following image. The Smart Bass Tuning page has all the controls needed for Smart Bass tuning. Several plots (such as Excursion) are provided as an aid to the tuning process. SLAA737B – March ...
You may want to collect data on how often there is a yes or no answer at decision points marked by a diamond- shaped symbol. If most decisions go one way rather than the other, you may be able to remove this decision point. 14 FLOWCHART Basic Tools for Process Improvement Interpreting ...
