For approximately eight years, MMS has helped to fund the development of RAPRENOx technology for offshore applications. This new technology has the potential to significantly reduce the NOx emissions from gas or diesel turbines used during offshore operations. Now, this technology development is moving into the private sector as its commercial viability becomes more certain.

RAPRENOx is a patented process for reducing nitrogen oxide gases emanating from gas or diesel turbine engines. RAPRENOx is nontoxic and is considered an effective means for achieving Clean Air Act NOx limitations offshore. The process uses isocyanic acid, formed by decomposition of cyanuric acid, a nontoxic, nonflammable, commercially available solid material. The gaseous isocyanuric acid is added to the exhaust stream whereby the NOx is reduced to N2, H2O, and CO2. Cyanuric acid is a solid, non-toxic compound that is safe to store and utilize around personnel in an offshore platform environment.
