Hi fresh Engineer

I think that the attached pdf files will be usefull for your understanding about your question.

The first one is from Carnegie Mellon University "Conceptual design process", and the another one is from PIPSTEP "Process Plan Activity Model".

Good luck

Hi again Fresh Engineer.

I think that the next few tips will be useful.

Basic and detailed engineering
Prior to the construction of an industrial plant, engineering studies are needed involving several engineering specialties such as:

• process
• pressure vessels
• rotating equipment
• instrumentation
• electrical facilities
• computing,
• piping, civil works
• cost control and scheduling

All these activities are covered and fully managed by the experienced Consulting Engineering firms.

According to the nature of a project, engineering studies will include all or part of the following steps:
1. Basic Engineering Design (BED) covering:

• Conceptual process studies (material balances, process flow sheets…) and preliminary plot plan.
• Preliminary Piping and Instrument Diagrams.
• Definition and sizing of main equipment resulting in process specifications.
• Specification of effluents.
• Definition of control and safety devices.
• And, generally speaking, all the basic studies required supporting a Basic Engineering Design Package (BEDP) containing all data needed by a competent contractor to perform the Detail Engineering.

These basic engineering studies may consist of consolidating a Process Package initiated by an external process licensor.

2. Front End Engineering Design (FEED) covering:

• Mechanical data sheets of the main equipment, starting from the process specifications issued during the BED and incorporating the specific requirements of codes and standards to be applied to the project in question.
• Thermal rating of heat exchangers.
• Preparation of tender packages for the main equipment.
• Development of process and utility Piping and Instrument Diagrams released for detail engineering.
• Development of detailed plot plans and hazardous areas.
• Elaboration of the main piping, instrument, electrical and civil works layouts.
• And, generally speaking, all the studies to be performed before ordering the main equipment.

3. Detail Engineering, covering:

• Purchasing of equipment, main and bulk.
• Thermal rating of heat exchangers.
• Development of Piping and Instrument Diagrams released for construction.
• Development of detailed piping drawings, including isometrics and stress calculations.
• Development of detailed drawings related to instrumentation, electrical facilities and civil works.
• Management of vendor drawings.
• Cost and schedule control.
• Start-up procedures.

And, generally speaking, all the studies to be performed before construction of the plant.

Good luck
