Posted on May 29, 2013

Siemens has concluded a framework agreement with China’s biggest oil and gas corporation, China National Petroleum Corporation (CNPC), to supply the entire electrical engineering and electrical systems for the first phase of the planned Guangdong Petrochemical Refinery in China.                  

Once completed, the refinery will be the largest in China. The first stage of the plant complex is scheduled for commissioning in late 2015.

The framework contract covers supply of the electrical equipment and all control systems for the entire refinery. This includes SF6 gas-insulated switchgear stations (GIS) with a rating of 220 kV as well as 220kV /110kV power transformers and 35kV/10kV distribution transformers, basic automation systems, PCS7 control systems, and 35 kV gas-insulated and 10 kV air-insulated switchgear. Protection and relay devices complete the current distribution.

Under the terms of a strategic cooperation agreement signed with CNPC in 2012, Siemens will also provide compressors for the air separation process and wastewater treatment solutions for the project. Overall, the three Siemens sectors – Energy, Industry and Infrastructure & Cities – are involved.

Siemens said that when the first phase of construction is finished, the refinery will be able to process 18.1 million tonnes of heavy oil per year. Completion of the second phase will boost the refinery's capacity to 45.3 million tonnes per year, playing a key role in meeting the country's booming demand for oil.
