LPG Reliquefaction COP
Simplified reliquefaction plant COP - boil-off absorbed / electrical compressor power.
Boil-off heat absorbed
194.4kW
Plant COP
0.43 -
Formula, assumptions, and limits
Typical propane reliquefaction COP ~0.4–0.6 (single-stage) to 0.8–1.2 (two-stage with cascade). Ammonia carriers use cascades because NH₃ needs low-T evap with high condensing P.
