Optimized Cascade Process Advantages
High Availability
- “Two-trains-in-one” configuration yields approximately 95% plant availability, with high efficiency during turndown
Proven Technology
- Nearly 50 years of operation
- 26 trains producing more than 105 MTPA at 12 plants
- Designed and built plants with broad range of ambient temperatures and feed compositions
- Low equipment count
Flexible Operations
- Easy to start up, shut down, operate and maintain, with fast startup cycles
and wide operating range - Cold boxes retain cold temperatures during extended outages, which translate into faster startup cycles
- Widest range of plant turndown capability (from 100% to 10% of nameplate capacity)
- Shifting load between refrigeration circuits allows for quick response to changes in operating conditions
High Thermal Efficiency and Low Emissions
- Use of brazed aluminum heat exchangers, aeroderivative gas turbines, and waste heat recovery integration, yields up to 96% LNG facility thermal efficiency and lower emissions
- Refrigerants retained in process and not flared during shutdowns
Integrated Design Operations
- Improve overall LNG plant efficiency and economics with integrated heavies removal and/or nitrogen rejection units
- Increase LNG production and efficiency with:
– Gas turbine power augmentation (inlet air chilling or humidification, water injection, etc.)
– Gas and flashing liquid expanders
– Combined cycle/cogeneration
