“…The adsorption capacities in both cases were similar (0.33 g/g and 0.25 g/g, respectively). 50 Small volatile hydrocarbons such as cyclohexane are frequently used to investigate adsorption properties related to physiosorption, 51 while organic phosphonates such as DMMP are used to mimic GB in adsorption studies because of their similar chemical properties, kinetic diameters, and content of polar functional groups. 52 However, GB is less stable than many OP-simulants used to assess adsorption behavior because its strongly electronegative fluorine center becomes an excellent leaving group.…”

Ammonia is a carbon free energy carrier that is gaining popularity as the next generation marine fuel. However, the adoption of ammonia by ships will not be feasible without solving the challenges during its bunkering operation, of which the utmost is the harmful effect from ammonia’s toxicity. A potential release of ammonia during bunkering operation will cause harmful impacts of various levels depending on its initial physical states, rate of release, total released inventory, local geometries, terrain and weather conditions. Without any mitigation measures in place, the released ammonia will undergo a complicated dispersion, dilution and uplifting pathway, affecting potential sensitive receptors in the surrounding. The knowledge and experience learnt from chemical, fertilizer and refrigeration use of ammonia provide valuable references for ammonia handling at sea and port. Mitigation for released ammonia can follow a two-pronged strategy: 1) the preventive strategy to reduce the likelihood of accidental release and 2) the protective strategy to reduce the release severity. This translates into mitigation technologies developed for pre-release scenarios and post-release scenarios. The pre-release mitigation considers inherent safer engineering design and good management, while the post-release mitigation focuses on early vapor detection and warning, containment, suppression, counter measures and emergency response. Nevertheless, there is a lack of understanding and use cases on how to extend the findings to ammonia bunkering operation, where the contact between ammonia and the sea environment, in particular sea water surface and column, is inevitable. The review provides a consolidated view on the applicability of land-based post-release mitigations such as physical containment, use of barriers, foams, dilutions and other chemical approaches to mitigation the consequences of accidental ammonia release from future ammonia bunkering operation.
