The thermodynamic analysis and adjusting methods for reliquefaction plant on board LEG carriers

摘要

The real capacity of the reliquefaction plant on board the ethylene carrier depends on the knowledge and skills of the ship cargo engineer to a great extent. Aimed at optimum operation, thermodynamic analyses are made on refrigerating cycles of the plant. The maximum cooling rate mode and the optimum energy-conservation mode are brought forward. Ethylene tank temperature is forecasted; optimum-operating mode is chosen and the division point is determined. Meanwhile, various influencing factors and working parameters of the plant are discussed in the paper.
