Field experience of Marine SCR
Selective Catalytic Reduction (SCR) is an established technology and has been used to remove acidic oxides of nitrogen (NOx) from the exhaust gases of engines, boilers and other combustion processes for over 50 years. The first SCR demonstration on a ship engine was conducted more than 30 years ago and since then over 500 vessels have installed SCR technology. Today, SCR is considered a proven, commercially available technology capable of removing 95% or more of NOx in an exhaust gas. As such, it is expected to be one of the major technical options capable of meeting IMO Tier III standards. Whilst there has been considerable success in the application of Marine SCR, the experience in the field is mixed and contrary messages have emerged. As part of the IMO NOx Review, the International Association for the Catalytic Control of Ship Emissions to Air (IACCSEA) committed to sponsoring an independent review of field experience of marine SCR. A database comprising most of the shipping SCR installations was compiled and a representative sample was surveyed. In this paper we propose to explore the following findings from the dataset and survey: 1. The extent to which SCR has been applied to a wide range of marine engine types, utilizing different fuels (of differing sulphur content) and operating over a range of engine conditions over the past 30 years. 2. The major problems that operators have had with SCR and a description of how these issues were managed, resolved or mitigated. 3. An outline of the most important lessons learnt that may be applicable during and after the transition to IMO Tier III.
