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.
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
China’s 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
Protection’s current emission requirements for SO2, NOx and sulfuric acid
"China’s 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 ZPC’s 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
