For every industry, there are some important Key Performance Indicators, called KPIs, which can be considered as criteria for process efficiency, perfiamcnce and efficacy.
My question refers to identification of most relevant KPIs in gas processing industry, mainly those that point to production, sweetening, energy consumption, operation, etc. If any one has an experience on this subject to share with me, or has any document (paper, report, book, powerpoint, etc.), I'd appreciate to receive them.
