18、d to enhance air quality, exhaust emissions regulations around the world are continuously strengthened. For ships with large combustion engines, particulate matter (PM), nitrogen oxide (NOx) emissions, and sulfur dioxide emissions are the main concern, and efforts have been focused on the developmen

19、t of technology that can reduce them effectively with minimum fuel economy penalty. Selective catalytic reduction (SCR) converters using a urea solution as the reducing agent is considered to be a key technology for reducing NOx emissions. The quality of the urea solution used for that technology ne

20、eds to be specified to ensure reliable and stable operation of the SCR converter systems. The ISO 18611 series provides the specifications for quality characteristics, for handling, transportation, and storage, as well as the test methods needed by manufacturers of SCR converters, by engine producer

21、s, by producers, distributors of the urea solution, and by fleet operators/ship owners.Efficient expanding of the use of urea SCR technology requires a consolidated framework that can be followed by producers, end users, OEMs, and catalyst suppliers.

22、BS ISO 18611-3:2014Ships and marine technology Marine NOx reduction agent AUS 40 Part 3: Handling, transportation and storage1 ScopeThis part of ISO 18611 describes best practice recommendations and requirements for handling, transportation, and storage of NOx reduction agent AUS 40 (aqueous urea so

23、lution), specified in ISO 18611-1. These recommendations and requirements are necessary to preserve the specified quality of AUS 40 from any point of production to the point where it is filled into the on-board tank of the vehicle, in order to ensure the proper function of the selective catalytic re

24、duction (SCR) converter systems.This International Standard is covering quality requirements and guidelines for AUS 40 for marine applications, irrespective of manufacturing method or technique.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this doc

31、ings, gaskets, hoses, etc.), all materials in direct contact with AUS 40 during handling, transportation, and storage, including sampling, shall be compatible with AUS 40.It is the responsibility of the user of this International Standard to ensure that the correct materials are used. The list of th

32、e materials given in Tables 1 and 2 shall be used for guidance only until such time as more definitive information is established.Any material with uncertain compatibility with AUS 40 shall be tested. The test conditions should reflect the intended temperature range and contact time, in order to eva

33、luate possible influences on the product quality as specified in this International Standard. In addition, this test shall ensure that the integrity of the material in contact with AUS 40 is maintained. Accelerated tests using higher temperatures can be used, as appropriate.If a contamination of AUS

34、 40 is detected during handling, transportation, and storage, an investigation shall be carried out to determine the causes of contamination and to take appropriate corrective actions.NOTE Choice of materials for the purpose of storing/distributing AUS40 on-board a vessel might be subject to special

45、 well as the evaporation of water in the case of vented containers, prolonged transportation or storing above 25 C should be avoided;NOTE 1 Insulation can be required, especially in hot areas of the world.NOTE 2 In hot areas of the world where there is a real risk of recommended long-term storage te

46、mperatures being exceeded, temperature monitoring of the AUS 40 is recommended.NOTE 3 Prolonged storage at temperatures above 25 C can reduce the shelf life (see Table 3). However, temporary exposure to higher temperatures does not necessarily influence the quality of AUS 40. in order to prevent sol

47、idification of AUS 40, storage below 1 C should be avoided;NOTE 4 Insulation or means of heating the AUS 40 can be required.NOTE 5 Solidified AUS 40 has a larger volume than the liquid and, therefore, can cause a fully filled, closed container to burst. Solidified AUS 40, which has been warmed up ca

48、refully at temperatures not exceeding 30 C will not be impaired in quality and can be used as soon as the warmed up solution is free from solids. in order to avoid excessive temperature rise, AUS 40 should be protected from sunlight; in order to protect AUS 40 from any contamination carried by the a

49、ir, well-closed containers or vented containers with filters should be used.Table 1 (continued) ISO 2014 All rights reserved 3BS ISO 18611-3:2014ISO 18611-3:2014(E)4.2.2 Shelf lifeThroughout the entire distribution chain, AUS 40 is expected to remain within the specifications given in this part of ISO 18611 for at least the time periods specified in Table 3 as a function of the constant fluid temperature, or if fluid temperature is not known, average ambient temperature at which the AUS 40 is stored provided it is not exposed
