How do I learn how to do this? What are the tools, skills sets and knowledge required to be able to do one for reciprocating compressor packages?

Thanks,

since it appears you are unfamiliar w/ pulsation studies for recip compressors, hightly recommend that you read through API-618 to gain an understanding.

to have pulsation study actually done, best to hire companies that have experience in this. two suggestions are SWRI (Southwest Research Institute) and Beta Machinery. you get what you pay for.

will need to work with designer and pulsation study company for pipe & compressor layout.

good luck
 
Hey Dev Ops,

Your best bet is to look at API-618 and ISO 13631 (API11P).
Both cover similar topics for reciprocating gas compression but they differ for speed and horsepower.

These codes provide a great baseline as to how to size pulsation bottles and piping systems. Most companies have there own tweaks or "best practices" they employee when doing this sizing as well based on experience.
In API-618 it dives deeper into the different design cases where thermal loading and vibration nodes come into play. This is where pipe stiffness, bottle chokes, orifice plate, shifting frequencies and come into play. At this point, it is not really possible to perform these calculations without some sort of program which has been design to do this specifically with a model and that has been fine tuned by engineers with a lot of experience in this field. This is where it is best to hire it out to someone rather than to try and do this yourself.

It is possible to make your own sizing calculator to get you close to what you are looking for. I have created one myself and have compared and verified against studies to ensure it is inline.
 
In addition to what has been mentioned by pmover, would like to mention the Dutch Organization TNO that can provide services for pulsation studies.

If you plan an escape, you must succeed as if you fail, you will be punished for trying. Never say or write down your plan. Heart is the only place where secrecy is granted.
