Dresser-Rand- STC-SX Compressor Series

Published on : Tuesday 30-11--0001

Innovative and Reliable

The Siemens STC-SX compressor type is optimally featured for today’s blast furnace requirements – which are characterized by the continuous strive for larger compressor units with increased efficiencies. Siemens axial flow compressors STC-SX have proven to meet customer needs: designed to handle large volume air flows and other clean gases within relatively small casings while maintaining excellent efficiency. Since 1950, the concept of Siemens STC-SX has continuously been optimized. Designed in accordance with API 617, this product line now allows for volume flow rates up to 1,300,000 m³/h.

Highlights

• The perfect match for large volume flows
• Excellent efficiency
• Low maintenance costs

Applications

• Blast furnace air
• FCC air
• Design Concept
• High Flow Rates at High Efficiencies
• Designed for large volume air flows and other clean gases within small casings, Siemens STC-SX compressor series guarantee excellent efficiency. Fulfilling highest technical standards, the compressor design is according to API 617.
• Casings have an axial or radial inlet. As standard, they are fabricated. On special request, Siemens also offers cast casings. These machines are typically uncooled straight-through compressors, optimal for high discharge temperatures.
• Modular Principle
• The design principle common to the Siemens STC-SX series is a modular concept. It is based on finely graded machine elements and flow components that have proven their reliability over many years of operation.

Highlights

• Tilting pad bearing for journal and axial thrust bearing
• Up to 19 stages
• Outstanding blading technology
• Rotor blades of first and second stage are made of duplex steel
• Corrosion resistance due to unique material usage

Control Systems

• Broad range of appropriate control systems
• Performance control
• Independent anti-surge protection
• Anti-choke control
• Control by either speed variation or adjustable guide vanes, or a combination of both

Technical Data

• Flow rates from 50,000 to 1,300,000 m³/h (30,000 to 825,000 cfm)
• Pressure ratio between 1.9 and 6.0
• Speed up to 9,000 rpm
• Discharge temperature up to 350°C
• Various control systems to optimize operation
• Driver: electric motor or steam turbine, depending on process and energy resources
