Siemens to Supply Compressor Solution for Coal-to-Urea Production

Siemens Energy has received an order from Vietnam for the supply of an air compressor train. Purchaser is Air Liquide Engineering South Asia. The compressor train will be deployed in a coal-to-urea production plant, which will be owned by the Vietnam National Chemical Corporation (Vinachem). The coal gasification plant is located in Ninh Bin approximately 80 kilometers south of Hanoi and is scheduled to start operation in 2011. The order volume is approximately EUR 8 million.

Siemens will supply a steam-turbine-driven compressor train comprising two STC-GV integrally geared turbocompressors (main air and booster air compressors), an SST-600 steam turbine and auxiliary systems. In the air separation unit the train will provide the oxygen required for coal gasification. The air will be compressed to the requisite process pressure of over 50 bar. The plant's annual capacity for coal-to-urea production will be approximately 560,000 metric tons. The integrally geared compressors will be produced in Duisburg and the steam turbine in Görlitz.

Urea is used in agriculture as part of fertilizers, in animal feedstock and in the field of medicine. It Is also a key primary product in the production of plastics and soaps. "Especially for innovative applications like coal to urea we can utilize our wealth of experience in air separation solutions," said Tom Blades, CEO of the Oil & Gas Division of Siemens Energy. "We also have a further advantage thanks to our know-how in coal gasification technology. We see this order for Vietnam as a milestone with a view to comparable applications."

Siemens has accumulated a wealth of experience in coal-based applications. Oxygen is essential for a wide variety of processes. Siemens has already supplied over 1,000 compressors for air separation units.

The Siemens Energy Sector is the world's leading supplier of a complete spectrum of products, services and solutions for the generation, transmission and distribution of power and for the extraction, conversion and transport of oil and gas.
