Siemens Turbocompressor - Single Shaft, Horizontally split casing
Siemens single-shaft centrifugal compressors with horizontally split casings in the STC-SH series can be used for the majority of process applications. Appropriate for process requirements such as medium pressures for a wide range of volume flows, the STC-SH is the preferred compressor for e. g. cracked gas, coker gas, process air or carbon dioxide.
The STC-SH is also available with an overhung impeller - a lower-cost alternative design for large volume applications especially with steam turbine drive.
Designed in accordance with API 617, this product line corresponds with all technical requirements imposed by the market.
With the integration of Siemens Turbomachinery Equipemt, the STC-SH series was extended and now even covers chlorine applications.
The design concept of STC-SH compressors is very flexible, allowing easy adaptation to the requirements of specific process applications (e .g. gas or water injection).
Casings are mostly fabricated, but can also be cast for special applications (e. g. low-temperature applications down to -163 °C / - 261 F°). Impellers and stator parts (e. g. return vanes) are tailor-made and 100% machined, thus ensuring high aerodynamic predictability. The horizontally split casing permits easy access to all compressor internals by simply removing the upper half of the casing.
These centrifugal compressors can be equipped with up to ten impellers per casing and each casing can contain as much as four process stages. Designs include straight-through, double-flow and back-to-back configurations. A well-proven, fully parametric aerodynamic design, based on comprehensive in-house research and development, allows for the perfect matching of compressor performance and rotor dynamics for any application. Compressors of the STC-SH series are project-specifically designed to meet individual customer needs.
Besides conventional oil-lubricated tilting pad bearings, active magnetic bearings can be used, allowing 100% oil-free operation of compression trains in combination with electric motors, which are available also with magnetic bearings.
