Optimized Cascade process advantages

High availability

• “Two-trains-in-one” configuration yields greater than 95% plant availability, with high efficiency during turndown.

Proven technology

• Over 60 years of design and operations experience.
• 120+ MTPA of licensed capacity.
• Designed and built plants with broad range of ambient temperatures and feed compositions.

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 changing operating conditions.

High thermal efficiency and low emissions

• Use of brazed aluminum heat exchangers, aeroderivative gas turbines, and waste heat recovery unit 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 thermal 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.
