Single Shaft Vertical Split Turbocompressors
This product line is suitable for a wide range of process gases and meets customers’ requirements in all types of industries, especially on/offshore oil & gas and downstream applications and LNG. Siemens centrifugal barrel-type turbocompressors feature a flexible, reliable and robust design – the perfect solution for higher pressures.
Siemens Turbocompressor - Single Shaft, Vertically split casing
The compressor series STC-SV is Siemens’ answer to the diversified needs in industrial process compression. From standard processes to high-pressure applications such as hydrocracking, syngas or gas storage and injection, STC-SV compressors are the ideal solution for a large number of applications. These compressor types realize a discharge pressure up to 1,000 bar. As all Siemens single-shaft compressors, STC-SV compressors are designed according to API 617.
The STC-SV (S) is also available as single-stage machine. This is a packaged-unit concept – compressor, driver and auxiliaries form one single-lift unit which facilitates transport and reduces site installation work to a minimum, realizing pressures up to 80
Designed to compress gases of any molecular weight and optimized for those with low molecular weight, STC-SV is ultimate for high pressure services, covering a discharge pressure range up to 1,000 bar.
All compressor internals assembled into a bundle allow easy axially removing form the casing shell without the need to remove process gas piping. A wide variety of sealing systems (labyrinth seals, carbon ring seals and mechanical dry gas seals) completes the reliable compressor design. Mechanical dry gas seals, in combination with active magnetic bearings for compressor and driver, yield the special economic and environmental benefits of dry-dry equipment operation.
The reliable advoidance of subsynchronous rotor vibration caused by gas forces in labyrinth seals and diffusers is the key to the high-pressure compressor design. Within sustainable research and development, Siemens provides a series STC-SV compressor supplying over 900 bar discharge pressure with nitrogen. Due to technical expertise, Siemens can reliably predict rotor-dynamic behavior in ultra-high pressure environments, with results verified in PTC 10 class 1 tests.
