Siemens to supply core compressor train for China PDH unit

Siemens Energy has received an order from China for the supply of two gas-turbine-driven axial-flow compressors trains for the first propane dehydrogenation (PDH) project in China. The purchaser is Tianjin Bohai Chemical Industry Group Co.; a company specialized in areas of the chemicals sector such as caustic soda, and the organic/inorganic/refined chemicals, rubber and plastic processing, and biochemicals industries. Currently, the demand for propylene in Asia is growing very fast. The implementation of PDH projects will facilitate China's own propylene production and the development of its downstream industries. Siemens will supply two sets of axial- flow compressors with the largest flow rate in the world driven by SGT-700 gas turbines. The plant in Bohua with a 60 mt/year polymer grade is the world's largest PDH plant to date, utilizing the Catofin dehydrogenation process developed by the U.S. company Lummus Technology.The new plant will produce propylene, which is a feedstock for the production of plastic. The incoming gas (propane) will be hydrogen-reduced to produce propylene. The Siemens compressor solution for the new plant encompasses two sets of axial flow compressors (STC-SX450-6V6), driven by its SGT-700 industrial gas turbines. Auxiliary systems such as control systems, dual fuel system, lube oil unit and air filter units are also part of the scope of supply. Each compressor has the world's largest flow rate: more than 700,000 m3/h of air will be compressed from atmosphere to 2.4 bar discharge pressure. The gas turbine is provided with a duel fuel system to operate the gas turbine with natural gas from a pipeline or with the feed gas of the plant, which is mainly propane. "The contract is a milestone for Siemens, and it establishes a very good position for us as a core player with its comprehensive compressor portfolio in the emerging PDH market in China," said Ralf Kannefass, head of the Turbo Equipment business segment in the Siemens Energy Oil & Gas Division.
