Cryogenic Plant Safety & Interlock Guide

Cryogenic plants rely heavily on interlocks and safety shutdown systems to prevent mechanical damage and personnel hazards. This micro-book explains the philosophy behind safety logic and how interlocks protect compressors, expanders, and cold box equipment.

It helps engineers understand trip events rather than treating them as nuisance alarms.
