文摘
- •
Propose a novel pressurized liquefaction process integrated with CO2 removal.
- •
Optimize proposed processes with and without precooling using energy criterion.
- •
CH4 refrigerant not only saves energy but also achieves a high liquefaction rate.
- •
CO2 precooling refrigerant is low in price and acceptable in energy efficiency.
- •
Using precooling reduces energy by more than 14% but also increases complexity.
