Symbols & Story TellingEarliest forms of communication during the prehistoric period were the Hieroglyphics and cave drawingsVersion - 1.0, January 2019Process Flow / Instrumentation Drawings5
Evolution of SymbolsPhoto captionVersion - 1.0, January 2019Process Flow / Instrumentation Drawings6
The Basics There are standards for symbols:– AutoCAD P&ID ISA – International society of automation– AutoCAD P&ID PIP – Process Industry Practices– AutoCAD P&ID ISO – International Organization forStandardization User defined “unique” symbols Use the symbol guide for the P&ID’s youare reading.Photo captionVersion - 1.0, January 2019Process Flow / Instrumentation Drawings7
Where Can P&IDs Used? Everywhere in our conveyance andtreatment systems:– Operator Training– Developing SOP’s– Process Troubleshooting– Conveyance Information– Storage InformationPhoto captionVersion - 1.0, January 2019Process Flow / Instrumentation Drawings8
Where Can P&IDs Used? Everywhere in our conveyance andtreatment systems:– Chemical feed systems– Hazard monitoring type and location– Sampling type and location– Security– Auxiliary servicesPhoto captionVersion - 1.0, January 2019Process Flow / Instrumentation Drawings9
PFD / P&ID Differences
The Process Flow Diagram Shows the flow of process and theequipment involved in the process. Shows the relationships between themajor components minus the details. Are sometimes used for visitorinformation and new employee training.Version - 1.0, January 2019Process Flow / Instrumentation Drawings11
A PFD should include: Process Piping Major equipment symbols, names andidentification numbers Control, valves and valves that affectoperation of the system Interconnection with other systemsVersion - 1.0, January 2019Process Flow / Instrumentation Drawings12
A PFD should include: Major bypass and recirculation lines Sometimes system ratings andoperational values as minimum, normaland maximum flow, temperature andpressure Composition of fluidsVersion - 1.0, January 2019Process Flow / Instrumentation Drawings13
More Basics Process always flows from left to right The whole process doesn’t always fit onone drawing Drawing numbers on the left side tellswhere the process is coming from Drawing number on the right side tellswhere the process is going toVersion - 1.0, January 2019Process Flow / Instrumentation Drawings14

3.0 PROCESS INSTRUMENTATION AND CONTROL SYSTEMS The systems discussed in this chapter are those that have to do with process instrumentation or process control. The control systems used to alter reactor core reactivity are discussed in Chapter 7. The process instrumentation and control
Change Control in SmartPlant Instrumentation - Because of the Critical and Dynamic nature of process data it is important that Change Management Procedures be in place on every project. - The Process Engineer is the Owner of the Process Data in SmartPlant Instrumentation Process Training for SmartPlant Instrumentation
Drawings are Engineering’s INTERNATIONAL LANGUAGE engineers all over the world can understand them. TYPES of DRAWINGS Process Flow Diagrams: What a Process Does Piping & Instrument Diagrams: How it works Layout Drawings: How it looks Mechanical Drawings: How to build it Construction Drawings: dwg1. Uses of P&IDs Develop Operational methodology Develop Safety .
12.2 ENGINEERING DRAWINGS Successful bridge fabrication and construction depend on the accuracy and completeness of the engineering drawings. Two types of drawings are normally used: design drawings and shop drawings. Design drawings show the structure configuration and provide information necessary for field assembly.
Planar Drawings A planar drawing is a drawing in which edges do not intersect each other in the drawing (for example, the drawings (a), (b), and (c) in Figure 5.1 are planar drawings, and the drawing (d) is a non-planar drawing). Planar drawings are normally easier to understand than non-planar drawings, i.e., drawings with edge-crossings .
2.0.3 Process Flow Diagrams versus Piping and Instrumentation Diagrams Piping and instrumentation diagrams diverge from process flow diagrams (PFD) through many facets. Provided by the International Society of Automation, “[A process flow diagram is a] drawing the shows the general proc
Another encounter attracting attention presently is the Battle of Bannockburn which, as every Scottish school pupil will know, took place some 700 years ago. September of this year will also be an important time in Scotia’s history, no matter which way the electorate throughout the country decides. In addition to all of the above, our Society celebrates its 10th Anniversary. Earlier in the .
