Historically, API 11P was the go-to standard for high-speed, packaged reciprocating compressors, typically driven by internal combustion engines or electric motors in oilfield production environments. These are often referred to as "separable" compressors, operating at higher rotational speeds (typically above 600 RPM) compared to heavy-duty process compressors. The Shift to ISO 13631 and API 618
