Compressor loaded Expanders with oil lubricated bearings. The expander and compressor wheels are mounted on a common shaft and the energy recovered from the expansion powers the compressor wheel, which can be used as a booster compressor. A double or triple shaft seal arrangement ensures no lube-oil leakage to the atmosphere or the process gas.
The TC is available in 6 frame sizes with a power range from 50 to 12’000 kW. Design is customized to fulfill customers’ requirements in terms of standards : API standards, local standards or customers’ best practice standards can be applied when requested.
Turbo expander with compressor mounted on a common shaft.
The “cartridge” design of the expander allows access to the rotating element without removing the expander casing and its cold box extension.
For easy maintenance, a spare “plug-in unit” (expander without casings usually named cartridge) allows customer to change all internal parts within a minimum of time and with maximum reliability.
Diffuser design allows low radial loads at all operating flows.
A modular lube oil system is feeding the bearings.
