Measuring hydrogen sulphide in marine fuels-new testing scheme

摘要

The updated IP 570/13a Determination of hydrogen sulphide in marine fuels-Rapid liquid phase extraction method provides an automatic and precise quantitative analysis of liquid phase hydrogen sulphide (H2S) below 1 mg/kg in marine fuels. Publication of the original method in 2009 enabled specification writers to set the maximum allowed H2S in marine fuels to be 2 mg/kg. The Concawe Report 8/13 Marine fuels and hydrogen sulphide published in 2013, stated: 'This new liquid phase H2S limit in ISO 8217 is intended to provide an additional margin of safety by reducing the risk that personnel are exposed to levels of H2S vapour that can cause sudden and severe health effects.'
