Abstract

Hazardous and noxious substances (HNS) leakage from ship accidents has been one of the major sources of ship pollutions. Due to the varieties of HNS, the complexity of physical and chemical properties, the harmfulness of potential accidents, and the difficulty of accident prevention, HNS leakage could cause huge social and environmental impacts. HNS emergency response methods and technologies are currently in the early and exploring stage. As a big HNS import and export country with the increasing transportation volume, the risk of HNS pollution accidents in the ports has been significantly increasing over the recent years. However, few studies have been conducted regarding the HNS response technology, especially to the adsorption performance of various adsorbents against HNS. Therefore, this study aims to calculate the degree of adsorption of different adsorbents by selecting the representative HNS, which are commonly transported in the volume, for example, benzene, styrene, and vegetable oil. For inert substances with low saturated vapor pressure (vegetable oil and styrene), the degree and rate of adsorption of the investigated materials were found to be inversely proportional to the mass per unit area (area density). Moreover, these investigated adsorbents were shown to exhibit a good adsorption retention rate against inert substances. This study can provide the technical standard to select the most suitable adsorbents for the relevant HNS leakage.

Highlights

The Protocol on Preparedness, Response and Co-operation to pollution incidents by Hazardous and Noxious Substances(OPRC-Hazardous and noxious substances (HNS) Protocol) follows the principles of the International Convention on Oil Pollution Preparedness, Response and Cooperation(OPRC), 1990 [1] and was formally adopted by States already Party to the OPRC Convention at a Diplomatic Conference held at International Maritime Organization(IMO) headquarters in London in March 2000
Like the OPRC Convention, the HNS Protocol aims to provide a global framework for international cooperation in combating major incidents or threats of marine pollution [3]
HNSs were selected for the large transport volume and low toxicity according to the list of 20 major chemicals, which are most likely to cause high risks in HNS accidents determined by the IMO [19]

Summary

Introduction

1.1 BackgroundThe Protocol on Preparedness, Response and Co-operation to pollution incidents by Hazardous and Noxious Substances(OPRC-HNS Protocol) follows the principles of the International Convention on Oil Pollution Preparedness, Response and Cooperation(OPRC), 1990 [1] and was formally adopted by States already Party to the OPRC Convention at a Diplomatic Conference held at International Maritime Organization(IMO) headquarters in London in March 2000. Like the OPRC Convention, the HNS Protocol aims to provide a global framework for international cooperation in combating major incidents or threats of marine pollution [3]. Due to the diversity of HNS varieties and different physical properties, HNSs exist in one or more of the following behaviors after the leakage into the water: dissolution, evaporation, floating, and sedimentation. The leakage indirectly affects the organisms and users in these ecosystems, leading to more serious damage to human health
