Two-stage cascade (−100 °C)
Propylene + ethylene cascade: the ethylene loop condenses inside a heat exchanger against the evaporating propylene loop and serves a −100 °C load. Two coupled closed cycles. From the ChemSep casebook (Refrigeration_2-Stage-100C).

Propylene → ethylene → methane cascade to −150 °C: each colder loop condenses against the next-warmer loop’s evaporator. From the ChemSep casebook (Refrigeration_3-Stage-150C).
