Non-API Compressors
Non-API Compressors
(OP)
Could someone educate me on the critical differences between non-API and API (617) compressors.
Application is for syngas compression to 500psig @400F.
Thanks

The API sections that are the most followed, are those that set to guide the pressure housing design, rotor dynamic design, and process connection design, and perhaps shaft sealing design.
As the customer you can require that certain parts of the API guidelines be followed, or you can allow exceptions to the API guidelines, as you feel is adequate for your application.
You should get a copy of API 617 and go through it yourself, to see what it really discusses.

I think api is basic and you wouldn't gain much by not using it..
Just my opinion.

We plan to use this compressor in a flammable gas service. Therefore the entire area around the compressor will be electrically classified.
The problem w/API 617 compressor is the delivery lead time which led us to evaluate a non API option. Needless to say this option is less expensive and saves us around 20 wks.
I presume that if we utilize 617 shaft seals and 617 recommendations for MOC of the shaft ans impellers we should be in relatively good shape.
As for Dlite's comment regarding going through 617. I have a copy, all 290 pages of it. Going through it I realized that it will take a good part of someones career to interpret it and do an intelligent comparison. That is why I asked the question in the first place!
