Process Designer technology gives to you the power to build up you specific process step by step exactly as you want.
A simple recipe allows you to change the pressure, temperature, flow rate of each component but can not change the process imposed by the PLC programmer. The Process Designer can do that: allows you to write every single step of the process as if it were a software program. The program will be compiled by a software compiler, stored in memory and recalled whenever you want. No limit to the recipes that can be associated to the new process.
The initial design analysis of a product design problem identifies constraints on physical and chemical properties. These constraints are used to generate design candidates that may have different compositions and possibly different forms. The composition, form, and physical properties of each of these product candidates, determines the required processing operations for its production.
A Process Flow Diagram - PFD - (or System Flow Diagram - SFD) shows the relationships between the major components in the system.
PFD also tabulate process design values for the components in different operating modes, typical minimum, normal and maximum. A PFD does not show minor components, piping systems, piping ratings and designations.
A PFD should include:
- Process Piping
- Major equipment symbols, names and identification numbers
- Control, valves and valves that affect operation of the system
- Interconnection with other systems
- Major bypass and recirculation lines
- System ratings and operational values as minimum, normal and maximum flow, temperature and pressure
- Composition of fluids
The Process Flow chart provides a visual representation of the steps in a process. Flow charts are also referred to as Process Mapping or Flow Diagrams. Constructing a flow chart is often one of the first activities of a process improvement effort, because of the following benefits:
- Gives everyone a clear understanding of the process
- Helps to identify non-value-added operations
- Facilitates teamwork and communication
- Keeps everyone on the same page
To draw a New Process Flow Chart you have to identify each step, write a function that describes this steps, and then you have to concatenate the different functions. If you succesfully complete all of this passages, the game is done. You have just created a new process.
