The Puguang Natural Gas Plant has been in operation since 2010. It produced more than eight percent of China’s total natural gas output in its first year of operation. It has also become a major supply of domestic elemental sulfur in China.
The Puguang gas field is one of the largest of its kind in Asia. Discovered in 2003, the field’s raw natural gas is sour, which means it must be purified before it can be used for commercial purposes. The sour gas at Puguang contains large volumes of hydrogen sulphide, in addition to having appreciable carbon dioxide content.
Black & Veatch helped the client overcome this challenge through its proven Interstage Cooling technology. This enhanced selective treating configuration is one of the key features of the design that enables the facility to significantly reduce the volume of inerts processed in the SRU as well as reduce capital and operating costs compared to other technologies.
