Compressor Selection by Service | API 617, 618, 619, 672 Explained

📝 DESCRIPTION

In this video, we break down Compressor Selection by Service using the major API standards: API 617 (centrifugal & axial), API 618 (reciprocating), API 619 (screw), and API 672 (integrally geared).
A must-watch for oil & gas engineers, rotating equipment engineers, and anyone preparing for technical interviews.

🔑 What You Will Learn in This Video

✅ Compressor Selection by Service
– Gas type, flow, pressure, molecular weight, duty cycles

✅ Compressor Families & Where They Excel
– Efficiency, pressure ratio, turn-down, reliability

✅ Centrifugal Compressors (API 617)
– High flow, moderate pressure, clean gas applications

✅ Integrally Geared Compressors (API 672)
– Compact, multistage, high efficiency for air & nitrogen

✅ Reciprocating Compressors (API 618)
– High pressure, low flow, dirty gas, intermittent services

✅ Screw Compressors (API 619)
– Oil-injected/dry, steady flow, refrigeration & gas boosting

✅ Axial Compressors (API 617)
– Very high flow, low pressure rise per stage

✅ Diaphragm Compressors (Specialized)
– Ultra-pure gas, hydrogen compression, zero contamination

✅ Duty Envelope Decision Cues
– When to pick which compressor type

✅ Quick Thermodynamic Calculations
– Rule-of-thumb sizing checks (polytropic work, PR, flow)

✅ Mini Quiz – Quick recap

✅ Interview Questions – Common questions in rotating equipment interviews

✅ Practical Task – Select a compressor type for a given gas service

💡 By the end, you’ll know exactly how to choose the right compressor for any service, and how to justify it in design reviews and interviews.
