Ocean-based thermal power FGD - an accelerator for global FGD Deployments at a large scale
  • Over 20 years of commercial operation proved that NSW FGD, which uses only natural seawater to reduce emissions without secondary chemical pollution, has higher desulfurization rates than FGD processes that rely on chemicals. Moreover, it can lower the cost by about 80%.
  • Through the demonstration of NSW FGD projects at the large-scale thermal power plants, NSW FGD has started and promoted the deployment of various FGD in the thermal power industry of China, facilitating the acceleration of the deployment of global land-based FGD.
  • Seawater scrubbing FGD thus becomes BAT.


Ocean-based ship exhaust reduction, ensuring a win-winsituation for MARPOL and climate mitigation.
  • ZCEIU designed and manufactured NSW EGC (Exhaust Gas Purification) (2011) for the RUIHE tanker, which is the world's first EGC system with a main engine that complies with IMO emission regulations.
  • Only use natural sea water to scrub ship exhaust, remove sulfur dioxide more than 90%.
  • On November 8, 2012, environmental technologies in maritime shipping & transportation: Implementing the UN protocols´╝îreleased by Mr. Sigan Peng when he was invited to speak at Stanford University.
  • IMO&EPA revised the relevant standards in 2013.

ZCEIU NSW FGD/EGC has CCS spillover function: a total of 6GW FGD of installed coal-fired power plants being commercial operated since January 2000, and a real sea trial marine ship of EGC in 2011.
Mr. Peng Sigan (ZCEIU/CEPT) addressed the chief speech on the promising marine NSW technology for energy and environmental control.
