Reciprocating Compressors 101 : The User's Perspective

Abstract

This course will present the basic concepts of reciprocating compressor applications from a user’s perspective. There is an introductory section on application basics (why recips?), including selection criteria and industry standards (API 618, etc.). Compressor components, the basic compression cycle, capacity control, pistons, rings, rods and lubrication essentials are covered. Technical details including PV diagrams, rod loads, rod reversal, torsional vibration as well as skid and foundation considerations are discussed. Some basic information on pulsation and vibration control is presented, including a discussion of the various API design approaches. Vibration and pulsation measurements are also included. The course is then summarized with basic “must have” design rules of thumb, life cycle considerations, layout and maintenance considerations, and several case histories to illustrate these concepts.
