Usual Gases Handled: The turbo expander with compressor brake TC is designed to handle gases such as air, nitrogen, waste gas with high oxygen or CO, CO2, sour natural gas, H2 & CH4 mixtures, LNG, NGL, and LPG. It can accept high liquid content at the outlet due to its unique design.

Typical Applications: This equipment is used in the industrial gas industry, particularly in air separation units for refrigeration when a process booster compressor is needed. In the oil and gas industry, it is used for natural gas treatment, dew point control, ethane recovery, LNG production, and NGL and LPG recovery. It is also applicable in petrochemical plants for refrigeration, such as in ethylene and ammonia/urea plants.

Features and Benefits: The turbo expander is mounted on a common shaft with a compressor. Its cartridge design allows easy access to the rotating element without removing the casing. A spare plug-in unit facilitates quick maintenance. The diffuser design minimizes radial loads, and a modular lube oil system supports the bearings. The expander package can be customized to meet stringent specifications like API617 and API614.

References: Cryostar has extensive experience with the TC design, having built the first unit in 1976 and sold over 500 units to major gas and hydrocarbon companies.

Other Available Expanders: Various models are available, including TFC, TCC, MTC, ECO, TP, TG, MTG, LTP, and LTG, each with specific features like cryogenic compressors, oil brakes, generators, and magnetic bearings.

Technical Specifications: The expander can handle flows up to 2.5 million Nm3/h, pressures up to 200 bar, and temperatures from -270°C to +200°C. It offers power up to 12000 kW. Models like TC120, TC200, TC300, TC400, TC500, TC600, TC700, and TC800 are available based on customer needs.

Range of Operation: The document details various configurations and combinations, such as TC300, 2TC, 2TC120/300, and TC120 ECO, highlighting the flexibility and adaptability of the equipment to different operational requirements.
