Thanks guys.

Quite a subjective question however operating pressure is determined by optimizing:
Separation efficiency
Energy consumption
Condenser feasibility
Fluid thermal stability
Column size & cost
Utility availability
Safety & equipment limits

What exactly this RP covers?
Does that talk about the responsibilities as well?

Good one.

Yes, that is possible.
Better to take PI admin support if you are not able to pull this data out.
Doing on valve-to-valve plotting basis is not practical if you have a considerable site size.

Most international operators combine:
API 521 / ISO 23251 (Design)
API 537 (Hardware details)
EPA or EU limits (Emission benchmarks)
IFC EHS (Financing requirement)
IOGP methane guidance
ISO 14001 EMS

Suspect tool failure if you observe:
Sudden torque drop
Unexplained pressure drop
Erratic WOB transfer
Sudden ROP change
Abnormal vibration
Loss of telemetry
Mud leakage at surface
Monitoring of these 7 parameters would help.

In amine production, what are the controlling factors to have effective amine ratio (MEA/DEA/TEA distribution in production) during the process?

Shutdown systems are often part of SIS architecture but still maintained under a specific shutdown program.
Maintenance too as we have observed with our maintenance teams is also not random.
Every SIF has:
. SIL 1/2/3 rating
. Proof testing interval
. Probability of failure on demand
DUring LOPA and ...

I can provide you an auditor perspective, and that should enable you to have a procedure in place:
Is there a register? So you develop one controlled through a procedure
Do seals match register (serial numbers)? Apply within the procedure to have this sort of a control (serial numbers)
Are valves in ...

What are the guidelines to have the right TYPE of check valve installed on a process stream?
Which one to be picked, and how those should be maintained?
