Zhejiang Petroleum awards DuPont contract for sulfuric acid regeneration unit

April 18/2017

MOSCOW (MRC) -- Zhejiang Petroleum and Chemical Co. (ZPC) in China has awarded and signed contracts for the engineering, technology license and proprietary equipment for a MECS sulfuric acid regeneration (SAR) unit, licensed by DuPont Clean Technologies, reported Hydrocarbonprocessing.

ZPC is constructing a greenfield refinery and petrochemical project on Dayushan Island, just off the coast of eastern China, near Shanghai and Ningbo. The USD15 B project is the largest privately led petrochemical and refining project in Chinas history. The project will be executed in two phases with the first phase coming online in late 2018. After completion, the complex will have a refining capacity of 40 MMtpy, or 800,000 bpd.

The MECS SAR unit for the ZPC petrochemical complex will have a capacity to regenerate 858 mt of spent sulfuric acid. The unit will produce a combination of products consisting of 98.3 wt% sulfuric acid, 99.2 wt% sulfuric acid, and 20% oleum. Furthermore, the MECS SAR unit is designed to meet the Chinese Ministry of Environmental Protections current emission requirements for SO2, NOx and sulfuric acid mist.

"Chinas Ministry of Environmental Protection has enacted some of the most stringent point source emission requirements in the world," said Jason Hartman, global market specialist for the MECS SAR technology. "DuPont Clean Technologies is uniquely positioned to meet these new standards through enhancements to our MECS SAR technology. These enhancements include the MECS Vectorwall furnace, DynaWave scrubbing and Brink mist eliminators. When built, the SAR unit at ZPCs petrochemical complex will achieve world-class environmental emissions, reliability and on-stream time."

Specific to the oil and gas industry, MECS offers solutions for treating sour off-gas from amine treaters and sour water strippers to achieve ultra-low emissions specifications. In place of, or in addition to, traditional Claus SRU / TGTU facilities, these solutions can incorporate wet gas scrubbing (DynaWave), direct wet gas conversion to sulfuric acid (SULFOX), and/or regenerative recovery of SO2 (SolvR).
