Hello fellow engineers!

Could you suggest some useful literature about pre-commissioning and commissioning in chemical and oil refining industries?

I'm interested in both pipelines and equipment, managing practice is also appreciated.

Thank you.

Hi,

 

There is a specific book: "Process Plant Commissioning" by David Horsley which should be of some guidance.

 

Regards,

Ankur.

Thank you sir.

If you are in new project, then read vendor manuals, every thing is mentioned in vendor manual for pre-commissioning and commissioning of equipment.

For license technology, then read manuals for technology supplier like UOP etc.

Hello,

*pre-commissioning procedures are normally developed by plant's technology licensor  and vary plant to plant

 

PLANT COMISSIONING AND PREPARATION PRIOR TO INITIAL START-UP CAN BE INVOLVE MAINLY FOLLOWING PROCRDURES

*Operational Check-Out

*Hydrostatic Testing 

*Final Inspection of Vessels

*Flushing of Lines

*Instruments (Transmitters, control valves, energising solenoids, interlock loop test etc) 

*Acid Cleaning of Compressor Lines 

*Breaking-In Pumps ( seal oil,lube oil, motor solo run, priming of pumps)

*Breaking-In Compressors ( suction/discharge knock-out drums, cooling medium for inter stage coolers seal flow) 

*Dry-Out and Boil-Out

*Catalyst Loading

*Tightness Test

NORMAL START-UP PROCEDURES  CAN BE INVOLVE FOLLOWING PROCEDURE

*Prestart-Up Check List 

*Make Area Safe

*Utilities Commissioning 

*Air Purging and Gas Blanketing of Non-Catalytic Sections 

*Catalytic Units Reactor Section Air Purging and Gas Blanketing 

*Heat Exchanger Activation

*Vacuum Test

*Establish Flow in the Unit 

*Inhibitor/Chemical Injections

*Adjust Operation to Obtain Quality

Thanks for your answers.

I've already participated in 2 commissioning processes (naphtha hdt and fixed-bed reformer). Just wanted to see whole picture, not only from position of process engineer

The best material i've layed my hands on so far is Martin Killcross's "Chemical and Process plant commissioning handbook"
