development of novel and sensitive methods for the determination of sulfide in aqueous samples by hydrogen sulfide generation inductively coupled plasma atomic Emission spectroscopy
Analytica Chimica Acta, 2008Co-Authors: Mireia Colon, José-luis Todolí, Manuela Hidalgo, Monica IglesiasAbstract:Abstract Two new, simple and accurate methods for the determination of sulfide (S2−) at low levels (μg L−1) in aqueous samples were developed. The generation of hydrogen sulfide (H2S) took place in a coil where sulfide reacted with hydrochloric acid. The resulting H2S was then introduced as a vapor into an inductively coupled plasma-atomic Emission spectrometer (ICP-AES) and Sulfur Emission intensity was measured at 180.669 nm. In comparison to when aqueous sulfide was introduced, the introduction of Sulfur as H2S enhanced the Sulfur signal Emission. By setting a gas separator at the end of the reaction coil, reduced Sulfur species in the form of H2S were removed from the water matrix, thus, interferences could be avoided. Alternatively, the gas separator was replaced by a nebulizer/spray chamber combination to introduce the sample matrix and reagents into the plasma. This methodology allowed the determination of both sulfide and sulfate in aqueous samples. For both methods the linear response was found to range from 5 μg L−1 to 25 mg L−1 of sulfide. Detection limits of 5 μg L−1 and 6 μg L−1 were obtained with and without the gas separator, respectively. These new methods were evaluated by comparison to the standard potentiometric method and were successfully applied to the analysis of reduced Sulfur species in environmental waters.

Characterization of Low Sulfur Fuel Oils (LSFO) – A new generation of marine fuel oils - OC2020 A-050
SINTEF Ocean AS, 2020Co-Authors: Sørheim, Kristin Rist, Daling, Per Snorre, Cooper David, Bust Ian, Faksness, Liv Guri, Altin Dag, Pettersen Thor-arne, Bakken, Oddveig MeretheAbstract:This Multi-client project "Characterization of Low Sulfur Fuel Oils (LSFO) - A new generation of marine fuel oils" has been a 1-year project (2019-2020). The project has been funded by MPRI/DFO Canada, ITOPF and the Norwegian Coastal Administration. In order to meet new requirements for lower Sulfur oxides (SOx) Emissions to the air, new generation of low Sulfur marine fuels are now replacing the traditional Intermediate bunker fuels and heavy fuel oils (like IFO 180 and IFO 380) with "Ultra Low Sulfur Oils" – ULSFO (S < 0.1 % m/m), for use in the Sulfur Emission Control Area (SECA) in Europe and North America from 2015, and a Global Sulfur Cap regulation was implemented from 2020 with "Very Low Sulfur Oils" (S < 0.5 %m/m). This project aims to provide responders better knowledge and preparedness for spills involving new generation of low Sulfur residual marine fuel oil on the market today. The project included laboratory studies on these LSFO oils with focus on fate and behaviour, potential toxicity and with relevance to the effectiveness of different oil spill response options (use of dispersants and in-situ burning). Test methodologies was also subjected to an interlaboratory study and experiments were performed both in Norway (SINTEF) and in Canada (SL Ross) on one of the tested oils.publishedVersio

Characterization of Low Sulfur Fuel Marine Fuel Oils (LSFO) - A new generation of marine fuel oils
SINTEF Ocean AS, 2020Co-Authors: Daling, Per Snorre, Sørheim, Kristin RistAbstract:This is a summary report of the Multi-client project "Characterization of Low Sulfur Fuel Oils (LSFO) – A new generation of marine fuel oils" (2019-2020). The project has been funded by MPRI/Fisheries and Ocean-DFO Canada, ITOPF (R&D Award) and the Norwegian Coastal Administration (NCA). In order to meet new requirements for lower Sulfur oxides (SOx) Emissions to the air, new generation of low Sulfur marine fuel oil (LSFO) are now replacing the traditional Intermediate fuels and heavy fuel oils (like IFO 180 and IFO 380) with "Ultra Low Sulfur Oils" – ULSFO (S ≤0.10 % m/m), for use in the Sulfur Emission Control Area (SECA) in Europe and North America from 2015, and a Global Sulfur Cap regulation was implemented from 2020 with "Very Low Sulfur Oils" (S ≤ 0.50 %m/m). This project aims to provide responders better knowledge and preparedness for spills involving new generation of low Sulfur residual marine fuel oil on the market today. The project included laboratory studies with focus on fate and behaviour, potential toxicity and with relevance to the effectiveness of different oil spill response options (use of dispersants and in-situ burning). Test methodologies was also subjected to an interlaboratory study and experiments performed both in Norway (SINTEF) and in Canada (SL Ross) on one of the tested oils. The companies mentioned in this report provided samples for investigation of the fuel’s characteristics when spilled in sea water to help with the development of an industry response strategy for a new generation of low-Sulfur fuel oils. Many of the low-Sulfur fuels being developed by the industry share similar compositions, so it is important to notice that the findings of this report are not unique to the fuel samples analysed. The results of this study are indicative of a new generation of marine fuel oil across the wider industry. Further laboratory analysis of low-Sulfur fuel oils from other suppliers is needed to give a clearer understanding of the characteristics and behaviours of individual products.publishedVersio
