- •
Three pressurized liquefaction processes for offshore natural gas are proposed.
- •
The proposed processes are simulated and optimized by the genetic algorithm.
- •
The cascade PLNG process saves energy by 46% and reduces heat transfer area by 42%.
- •
The SMR PLNG process saves energy by 50% and reduces heat transfer area by 25%.
- •
The expander PLNG process saves energy by 63% and reduces heat transfer area by 4%.
