CPC Taoyuan starts up sulfur recovery units with DuPont technology
WILMINGTON, DEL. — The Chinese Petroleum Corporation (CPC) awarded DuPont Clean Technologies (DuPont) the contract to supply the technology license, engineering and proprietary equipment for a MECS DynaWave wet gas scrubbing unit to be installed at its Taoyuan refinery in Taiwan in August 2015. This scrubbing system has recently gone into operation for two sulfur recovery units (SRUs) at the site, in time for CPC to comply with strict emissions reduction regulations.
In the past, seven to eight days were required after turnaround of the SRUs at the CPC refinery before acid gas could be fed to the units and commence normal operation. As a result, off-gas from the catalyst would be released directly to the stack and into the air, causing environmental issues. CPC researched different solutions to resolve these issues, and finally opted for the MECS DynaWave scrubber, a scrubbing technology licensed by DuPont.
Licensed by DuPont, MECS DynaWave scrubbers are designed to work with a variety of reagents and handle multiple functions in one vessel. As such, the process makes it possible to quench the incinerated gas and remove potential particulates while absorbing the remaining acids from the Claus TGTUs. The technology also offers the flexibility of bypassing the SRU or the SRU tail gas system during maintenance and repairs, so operations can continue without interruption.
