Expander

Designed to maximize value from process waste gas, recovering energy from both heat and pressure sources

Benefits

Optimized design with special metallurgy and features for long life in any process conditions (5 years of uninterrupted running)
Full testing including mechanical integrity (4 hrs running @MCS above 1,000°F (538°C), and performance evaluation at site
Parts and design upgrades available for installed units from Baker Hughes and other OEMs

Features

Outer casings designed according to ASME standards with heat treatment for optimal structural and corrosion resistance
Integral stator shroud improves efficiency and reduces cone stress while improving maintainability and ease of disassembly
Optimized aerodynamic gas path for high efficiency and minimum erosion by using state-of-the-art design and protective coatings

Applications

Fluid catalytic cracking (FCC)
Otherwise wasted flue gas
Baker Hughes's hot gas expanders are available in a wide range of frames and sizes to best match any demanding FCC tail-gas recovery application. The single-stage design with highly accurate flow-path enable high reliability and maintainability, and best-in-class performance.
Power and cost recovery

An average 18 MW Baker Hughes hot gas expander for power recovery can save approximately $9 million per year in refinery electricity costs, and avoid more than 244,000 metric tons of CO2 emission per year.
