Siemens RefinesTurbocompressor for Coking

Efficiency improved up to 15%


Published:

Siemens Energy has improved its STC-SOL turbocompressor for coking industry applications by reducing the number of casting components and using an impeller technology that improves compressor efficiency up to 15%.

The STC-SOL single-stage radial compressor has modernized impeller geometry proven in applications with contaminated gases, such as in the sulfur industry. The compressor inlet chest and volute casing will be fabricated from a single casting, reducing the number of casing components from seven to two, thus enhancing safety and reliability.

Siemens said the design has fewer compressor surfaces that require sealing against the contaminated and toxic gases used in the coking industry. The horizontal joint of the compressor casing also ensures short down times during plant maintenance.

The company makes the STC-SOL compressor at its Frankenthal, Germany, development and manufacturing site.
