Siemens manufactures world’s largest gear compressor rotor

Siemens has manufactured the largest geared compressor rotor in the world. Testing was conducted at its facility in Duisburg, Germany. The first-stage impeller has a diameter of 1.8 m. The STC-GV compressor rotor is part of an order placed by UK-based Air Products PLC. The order includes 19 STC-GV integrally geared compressors for the air separation unit of the Jazan integrated gasification combined cycle power plant (IGCC) in Saudi Arabia.

The air separation facility will supply 75 000 tpd to a facility in the Jazan province on the coast of the Red Sea. The air separation plant will be operated by Jazan Gas Projects Co. Siemens will proovide seven model STC-GV main air compressors, six STC-GV booster air compressors and six model STC-GV nitrogen. The nitrogen compressor power is significantly higher than normally seen on high pressure integrally geared compressors.

“This project proves that we have the necessary capabilities to provide large air separation plants with the appropriate compression equipment,” said ThomasMoenk, head of Product Development and Technology for the Dresser-Rand business, part of Siemens Power and Gas. “The STC-GV compressors with theircustomised design are the largest integrally geared main air compressors ever built. This is a tremendous demonstration of our technical expertise.”

“We appreciate the ingenuity the Siemens team brought to this project. We especially valued the Siemens and Air Products joint team dynamic andcollaboration throughout the design, manufacturing and testing phases which resulted in a timely delivery,” said David Edmondson, Vice President GlobalEngineering & Manufacturing and Jazan Project Director at Air Products PLC.
