The most important reason and benefit of measuring H2S in liquid phase is that it deals with the key issue, which is to measure the potential latent H2S concentration of the fuel oil that could be released over a period of time from a bunker fuel at any suitable conditions, when the fuel is transferred, heated and agitated by the rolling action of the ship, rather than the measurement of variable equilibrium dynamics of the vapour phase.

Changes for Residual Fuels only are: Since the GTL products are paraffinic hydrocarbons and they are undistinguishable from the rest of the petroleum based marine fuel, no actual reference needs to be made for GTL synthesized hydrocarbons in the scope of the standard. Each country means one member.

Perhaps we are moving in the direction of higher quality residual fuels suitable for use in the engine without the need to first clean it. H2S – the new limit will only be applied from 1 Julywhich will allow the industry to gain global experience of the prevailing levels and with the new test method.

As the scope of ISO refers to petroleum derived products, the inclusion of any bio-derived products is ruled out. This is required as there is no known generalised experience in respect of storage, handling, treatment and service performance including overboard discharges of biodiesel within the broad spectrum of the marine environment.

The experiences gained with operation on low sulphur fuels, air quality, ship safety, engine performance, crew health as well as operational aspects and other changes of the bunker market realities were the main drivers for WG6 work and the agreed changes considered necessary were introduced into the standard.

In view of the difficulty of establishing a wording that fuel 88216-1 free of ULO, the WG agreed that it should be expressed in terms 8216–1 when a fuel does contain ULO and amend the wording in Table 2 as follows: The isl for Residual Fuels are set at max limit of 2.

A fuel shall be free from ULO. Although we endeavour to maintain an up-to-date catalogue, on occasion we may not have the latest version of a document, including where it has not yet been provided through an international feed. Current membership stands at 47 experts from all sides of the marine industry such as: The issues that could not be resolved during this revision will be debated for the next revision and these are:.

Changes to both Distillate and Residual Fuels are: The GTL products clearly fall within the 821-61 of the standard, unlike bio-derived materials which are specifically excluded.

Although the time frame of the development of the oso edition might have looked tight, the WG6 took the necessary time to consider all issues. ISO occupies a position between the private and public sectors, because some member institutes are part of the government structure in their countries but also there are other members who represent the private sector working in industry associations.

Another most important consideration is when a supplier delivers fuel to a customer, the supplier should measure the presence of H2S in the liquid phase of the fuel in order to provide an indication of the maximum amount of H2S that may emerge from the liquid phase during subsequent handling of the fuel. ISO is a non-governmental organisation and is a network of the national standards institutes with the Central Secretariat located in Geneva.

Achieving universal agreement on contentious issues connected with today’s marine fuels is a good achievement, which was not easy. Changes in ISO Measurement 82161 H2S, using Draeger tube in vapour phase, as per standard test method ASTM Dwhile totally appropriate as an occupational health protection measure, has its limitations.

International Classification for Standards ICS izo an international classification system for technical standards. Notify me of new comments on this article. Vapour phase measurements in ship’s tank head space are strongly influenced not only by the amount of H2S in the liquid phase but also by factors such as: The fourth edition of the marine fuels standard has delivered more significant changes than ever before and will give all stakeholders confidence in improved fuel quality for this and future generations.

ISO – European Standards

A fuel shall be considered to contain ULO when either one of the following conditions is met: If you need help with the purchase or have any queries please email enquiries standards. The basis for including CCAI was as a substitute for a minimum viscosity limit.

While bio-derived fuels can be produced by other process methods there is no general experience with regard to their application in marine systems and hence this Standard does not address those issues. The new limit will ensure that the whole industry follows a precautionary practice. However, because of its potentially fatal nature, operators of fuel storage terminals have prevented H2S from entering the supply chain system.

Additionally there are a variety of different sourced FAME products each with its own isso characteristics having implications in respect of storage, handling, 82161- engine operations and emissions.

Categories of marine fuels”. As a result of IMO regulations, there is much increased awareness of safety, health and environmental issues. The ISO entitled “Classification of marine fuels” has been revised and now it comprises: The new combination of elements will not trigger incorrect identification of ULO.

Fuel containers – Portable – Plastics and metal You may be interested in this related standard Automotive biodiesel – Specification for manufacture and blending You may be interested in this related 826-1.

However some countries may wish to adopt ISO standards as part of their regulations or legislations, for which they serve as the technical basis.

Acid number limits included Hydrogen sulphide H2S limits included Acid Number — the limits for Distillate fuels were adopted from the accepted industry’s guiding limit of 0. The experts represent 14 countries worldwide.

It is therefore not appropriate to consider a vapour space measurement as part of a sales specification. However the practice of blending FAME into automotive diesel makes isl almost inevitable, under current supply processes, that some marine distillates, and even perhaps marine residual fuels, may contain FAME as a result of cross contamination within the distribution system.

Categories of marine fuels This document has ixo re-assessed by the committee, and judged to still be up to date. However vapour space measurement are appropriate to verify operational conditions on board a ship for crew health protection.

For other products, uso as biomass to liquid BMTL and hydrotreated vegetable oil HVOthe WG maintained that these shall be considered as a separate issue for discussion during the next revision of the standard.

As a non-governmental organisation ISO has no legal authority to enforce standards implementation. In addition, today’s non-marine distillate fuels can contain a significant amount of bio-derived components, which might impact sio the oxidation stability of the fuel.
