Compressor Train Solutions out of one hand
We do not just sell turbocompressors. We have a unique compressor train competence from which our customers can benefit.
Whatever your process requirements are, Siemens offers the compressor solution you are looking for. From a single machine to a complex compressor train, we offer a tailor-made compression solution.
Siemens compressors, drives – steam or gas turbine or electrical motor –, controls and other auxiliaries are designed and perfectly matched to meet individual customer needs. Outstanding knowledge of interaction between the components - particularly the main rotating parts - is a result of decades of experience in this field. We can predict reliably how our compressor trains optimize your processes.
Siemens manages the interfaces and guarantees the system's performance as required and specified. Our customers can rely on a sophisticated compression solution and do not simply purchase an assortment of hardware.
In addition to manufacturing and assembling compressor trains, Siemens is one step ahead. The new workshop facility in Duisburg, Germany, allows to test large compressor trains, driven by steam or gas turbines or electric motors. With this mega test center, Siemens is a leading player in the growing markets of large applications by providing adequate test bed facilities and machining capabilities matching our customers' demands.
Technical Highlights:
- Electric motor drive up to 100 MW coupling power
- Steam turbine drive up to 35 MW coupling power
- Gas turbine drive up to 160 MW coupling power
Best in Test – Mega Test Center Duisburg
With the Mega Test Center, brought into operation at the beginning of 2008, Siemens is underpinning its compressor train expertise in the oil & gas and process industry. This includes compression solutions for refineries, chemical and petrochemical plants, natural gas transport or storage and air separation.
Siemens is fully up to date and can offer appropriate test conditions for future oriented machines. These include LNG (Liquefied Natural Gas), E-LNG or the production of liquid fuels and chemicals from coal or gas (Coal-to-Liquids, Gas-to-Liquids).

The All-Rounder
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
Highlights
- The perfect match for low molecular weight and ultra-high pressure processes
- Optimum compressor performance and rotor dynamics
- Robust design allowing high nozzle loads
Fields of Application
- Petrochemical plants
- Methanol plants
- Refineries
- Fertilizers
- Oil & Gas Industry (on-/offshore); compression solutions for:
> Natural Gas (e. g. gas transmission / gas pipelines)
> Liquefied Natural Gas (LNG)
> FPSOs
> Boil Off Gas (BOG)
> End Flash Gas (EFG)
> Fluid Catalytic Cracking (FCC) / wet gas
> Sour Gas (gas gathering, gas / oil separation)
Due to flexible design and sophisticated technology, Siemens SCT-SV compressors represent the following benefits to strengthen your industrial processes:
Reliable Design
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 from 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.
Sophisticated Technology
The reliable avoidance 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.
