PFD and P&ID Development using Autocad P&ID

Enough is enough. We are just trained to read PFDs and P&ID developed by others and boast about it. You see, preparation and development of PFD and P&ID are just carried out based on some algorithm to which you do not have any access! EIEPD PFD and P&ID Development course provides you with all of these design notes for typical equipment from towers to pumps. More importantly you learn where to prepare P&ID pages: Auto-Cad P&ID. We guarantee your success if you follow our instructions closely.

PFD Development

Session 1: Design criteria for PFD development

The instructor starts the session with the purpose of PFD issue, its format, and work procedure. Then he continues with general drafting instruction such as scales, types of lines, crossover, utility lines and flow directions. Then he shows how instrument and control system should be shown. In addition, you are taught how fixed equipment such as heat exchanger, air coolers, fired heaters, reactors, towers, and rotary equipment namely pumps, expanders, compressors and so on is shown on a PFD.

Session 2: Example of PFD development

In this session, the presenter provides learners with a comprehensive example. In this example you will learn the followings:

1. Developing the process sketch using EIEPD-STEPWISE Methodology

2. Vessel rule regarding vertical or horizontal

3. Air cooler rule T=65

4. Design notes for compressor

5. Pressure drops calculations and the need for compressor.

Now he introduces three steps of PFD development in a pragmatic way, first of which being the developed process sketch. The second step being inclusion legend, stream table, operating conditions, stream numbering and equipment tag. In third step, which equipment needs control loop and shows how to apply them on a real PFD.

Finally, he provides the PFD development check list and common mistakes by junior process engineers.

Auto-cad P&ID Intro

Session 3: Auto-cad P&ID Introduction

In this session you get to know how to define a new project, get familiar with Tool Pallete, project set-up and other miscellaneous features.

Session 4: Practice

In this session the trainer opens a page of P&ID of an existing plant which includes process lines, a separator with mist eliminator, heat exchanger, centrifugal pumps, air cooler, and valves. In this session you see and observe how he connects the lines (primary and secondary lines) to different equipment, draws a separator with its instrumentation, draws pumps with the piping around them, and draw control valves with their bypass assembly around them. He develops it from scratch to completion.

Session 5: Practice-Continued

This session is the follow-up of the previous session. In previous session you learned how to developed the P&ID page based on Auto-cad equipment icons. In this session you learn how to change icons based on your project P&ID equipment icons (for example you can’t find a separator with mist eliminator in Auto-cad but your project might have a lot of them, you learn how to add it. That is one example. In a technical perspective, you learn how to edit blocks. More importantly, you learn how to adjust and edit blocks from project set-up. You also learn how to export the file. Finally, you learn how to develop, import and export line list, equipment list and how to get various report out of Smart Auto-cad P&ID.

P&ID Development for Equipment

Session 6: Introduction

Session 7: P&ID development for separators and  distillation columns

Session 8: P&ID development for heat exchangers

In this session you will learn:

1. How to show different types of reboilers and which indications and notes should be stated in P&ID.

2. A note about steam reboiler duty controls, how to show each control approach and which note should be given.

3. A note about condenser duty controls, how to show each control approach and which note should be given.

4. Typical arrangement for water-cooled heat exchanger

5. Typical arrangement for on-stream maintenance facilities

Session 9: P&ID development for air-cooled heat exchangers

In this session you will learn:

– A note for air coolers manifold piping including different types, type selection criteria, sizing criteria and terminal type based on process fluid being single phase and mixed phase.

– A note for air coolers temperature control like inverter control, fan pitch control, louver control, bypass control and air circulation.

– The corresponding P&ID for each of outlet temperature control.

Session 10: P&ID development for furnaces

This session covers instructions for the following four sections:

– Process Fluid Heating Section

– Fuel Supply and Burner Control Section

– Combustion Air Supply Section, where forced air supply or air preheater (APH) is installed

– Decoking or Descaling Facility Section, if applicable

Finally, the speaker presents the typical P&ID arrangement for each of these sections.

Session 11: P&ID development for pumps

In this session he provides the typical P&ID for the following condition and more importantly explains the procedure and the reasons behind this developed P&ID arrangement.

– Typical fluids

– Fluids with operating temperature more than 170C

– Fluids with operating temperature less than 0C

– Vacuum services

– Slurry service

– High pour point

– High volatility

The instructor also talks about different types of protection for minimum flow and compares them from operational and economical point of view. Additionally, he provides the corresponding P&ID.

He gives instruction about P&ID development of reciprocating and rotary pumps. Finally, he provides good notes on strainers

Session 12: Example

In this session, a real page of P&ID is developed from scratch using all aforementioned typical arrangement and subsequently the whole P&ID page is drawn in Auto-cad P&ID, aiming to boost the learner’s capability in using Auto-cad P&ID alongside the knowledge they have learned.


Session 13: Purge-out operation

In this session you will learn the followings:

– Purge-out method

– Location of purge-out connection

– Connection size for purge-out

– Typical arrangement

Session 14: Vent and drain system

Of the vent and drain facilities which are most frequently applied in actual plants, the focus here is placed on the following:

– Vent to flare

– Vessel vent/drain

– Instrument vent/drain

– High point vent/low point drain

– Drain recovery system

Session 15: Miscellaneous piping arrangement

In this session the following subjects will be discussed:

– Line class breakpoint

– Control valve assembly

– PSVs piping layout

– Reverse flow protection

– Battery limit

– Sampling connection

– Steam trap

Hose connection


Session16: Transmitters

In this session a brief but practical presentation towards flowmeter and temperature transmitter will be given by the speaker; Afterwards, he provides instruction on piping layout requirement for transmitters, how to show them on P&ID and which notes should be provided before issuing P&ID.

Session 17: Miscellaneous

In this session the followings will be covered:

– Requirement of temperature and pressure compensation

– Failure action of control valves

– Special instrumentation (online stream analyzer and custody transfer)

Session 18: Typical instrument indication on P&ID

Session 19: Example

In order to help the learners better understand the aforementioned arrangements, the instructor in this session provides an actual and practical example in which he tries to develop a P&ID page using Auto-cad P&ID.

Answer the following questions to help you take the course or not.

1. Are you able to draw a page of P&ID using Auto-Cad P&ID?

2. Do you know how to develop P&ID around air-coolers based on their controlling system and the fluid being single or mixed phase?

3. How much do you know about class break point, isolation philosophy, or battery limit?

4. Do you know that the piping layout around pumps changes based on their operating temperature and the type of pumping fluid?

5. How much do you know about furnaces and what to show on P&ID?

6. Do you know how to prepare and develop(not read) PFD from scratch?


Be honest with yourself and for each question give yourself a score out of 10. If the sum is less than 30, then take the course; if the score is between 30 to 50, consult with us. If it is more than 50, we think you don’t need to take it.
