Chinese gas plant installs H2S, CO2 treating in eastern plant

HOUSTON, Dec. 22 --
Sinopec’s 1.27-bcfd Puguang natural gas plant in China’s eastern Sichuan province is using Black & Veatch’s Interstage Cooling technology to remove H2S and CO2 from feed gas produced from Puguang field.

The Puguang gas plant produces up to 8,400 tonnes/day and 3 million tonnes/year of sulfur. The processing plant removes virtually all the H2S, which comprises nearly 15% of the raw gas, and converts it to elemental sulfur. It also reduces CO2 to 3 vol % from 10 vol %, according to the Black & Veatch announcement.

The company is providing process design engineering, technology licensing, and field support services as part of a sour-gas purification and sulfur-recovery scheme.

The giant gas field, with proven original gas in place of more than 12.5 tcf, was discovered in 2003 in the eastern Sichuan basin. In addition to the Puguang gas plant, Black & Veatch says it has recently provided process engineering and technology licensing for PetroChina’s Longgas sour-gas field development in Sichuan province, a field discovered in 2006.
