New system
Start from the process specification and define the compressor duty from zero.
Use this page to collect the engineering inputs needed to review an oxygen duty against source-documented compressor platforms.

The source process-gas examples do not list oxygen, so this information is required before any O2 service claim is made.
Start from the process specification and define the compressor duty from zero.
Use 20-40 bar source families only as platform candidates until O2 suitability is approved.
Provide old documentation, photos and current operating conditions.
Document oxygen percentage and contaminants instead of assuming compatibility from another gas.
