LTG - turbo expander with low or high voltage generator and usually with gear box.
LTP - turbo expander with oil pump brake on a common shaft.
A significant improvement of the refrigeration cycle efficiency and power savings between 1 % and 3 % of the total power consumption of the plant.
The “cartridge” design of the expander allows access to the rotating element without removing the expander casing (and its cold box extension or annex plate).
Usual gases handled: air, nitrogen, or waste gas from air with higher oxygen content, Liquefied Natural Gas, mixed-refrigerants (propane, butane).
