Turbocompressors from Siemens –
covering the complete spectrum
Siemens offers a full range of turbocompressors to meet the needs of the oil and gas and process industries: in-line, axial or axial-radial, or integrally geared compressors can be matched with a range of drivers – steam turbine, gas turbine or electric motor – in a solution to match each unique customer
A wide range of products and a wealth of experience
With our unrivalled competence in complete compressor train solutions from a single source, Siemens offers an extensive range of standard or customized compressor solutions (Siemens Turbocompressors – STCTM). Our standard units with predefi- ned engineering options ensure low investment costs and short delivery times. For the more complex processes such as Gas-to-Liquids (GTL), Coal-to-Liquids (CTL), methanol and integrated gasification combined cycle plants (IGCC), we provide a uniquely tailored solution.
Air separation, petrochemical plants & refineries, catalyst regeneration and synthetic fiber production are amongst the most common applications for our compression solutions.
Catering for mega-scale applications
As a technology of the future, GTL is worth a mention in its own right. This complex process demands a considerable variety of very large rotating machinery. Siemens offers compression and power generation packages for air separation, the syngas process and the refinery process with its own steam turbine, gas turbine or electric motor drive. Siemens has successfully supplied the largest air compressors and the largest mechanical drive steam turbines ever made. This experience makes Siemens the partner of choice for all compression and power requirements in all sections of the GTL process up to a complete power Island
The comprehensive portfolio
STC- SR
The perfect match for large air volume flows
Siemens STC-SR axial-radial isothermal turbocompressors are the perfect solution to handle large volume air flows whilst maintaining excellent efficiencies. The STC-SR series is ideal for applications requiring higher pressure ratios and intercooling. The design incorporates an axial process stage followed by one or more centrifugal process stages. STC-SR compressors combine excellent efficiency with highest quality due to proven components and compliance with API standards.

The comprehensive portfolio
STC-SX
The optimum solution for blast furnace air
The STC-SX series are axial-flow compressors designed to handle large volume air flows and other clean gases within relatively small casings. This axial-flow turbocompressor is typically an uncooled straight-through compressor, designed for discharge temperatures up to 350°C. Outstanding blading technology and unique material usage result in optimized performance and reliability.
Technical data
• Flow rates from 50,000 to 1,300,000 m3/h
• Pressure ratio between 1.9 and 6.0
• Driver of your choice
Fields of application
• Blast furnace air
• FCC air (Fluid Catalytic Cracking)
Features
• Excellent efficiency
• Modular design principle
• Extended operation range
• Highest quality standards
• Casings with axial inlets
• Up to 19 axial compression stages
STC-SV
The Allrounder
The STC-SV is a single-shaft centrifugal compressor with vertically split barrel-type casing, designed for direct drive concepts in accordance with API 617. All compressor internals are assembled into one bundle for easy installation and maintenance. The STC-SV allows for perfect matching of compressor performance and rotor dynamics and is the perfect solution to compress gases of any molecular weight.
The single-stage STC-SV (S) 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.
Technical data
• Flow rates from 250 to 480,000 m3/h
• Discharge pressure up to 1,000 bar
• Driver of your choice
Fields of application
• On/offshore oil and gas
• Petrochemicals
• Methanol
