SBIR Phase II: Biological Treatment of Hydrocarbons in Shipboard Exhaust Gas Cleaning Systems

该小型企业创新研究（SBIR）二期项目将解决航运业颁布的要求减少发动机排放硫氧化物（SOx）的新法规。许多商用洗涤器系统都能有效地去除发动机排放物中的硫氧化物，但没有一个是专门用于去除多环芳烃（PAHs）的。EnSolve吗?我们的方法是开发一种生物和机械相结合的系统，可以从洗涤系统废水中去除多环芳烃。I期研究的结果证实，生物力学方法在减少多环芳烃方面是有效的，减少率超过99%。这项研究的更广泛影响将是为海运业提供一种成本效益高、可靠和环保的处理系统，用于从世界上清除有毒物质。年代的海洋。船舶将被要求要么安装洗涤设备，要么改用更昂贵的低硫燃料。改用低硫燃料将使目前的燃料成本增加88%以上。与购买低硫燃料相比，使用洗涤器系统的商业船东可以实现每艘船每年节省200万美元的燃料成本。预计将有3.5万艘船舶受到这些法规的影响，这将为拟议的洗涤器水处理系统带来超过50亿美元的市场机会。正在开发的其他技术利用纯物理分离方法，将污染物从洗涤器水中转移到另一介质（即过滤器）进行处理。相反，拟议的生物方法是一种再生过程，将大大减少垃圾填埋处理，消耗品，劳动力和责任成本。

This Small Business Innovation Research (SBIR) Phase II project will address new regulations being enacted inthe shipping industry requiring Sulfur Oxides (SOx) reduction from engine emissions. Many commercialscrubber systems effectively remove SOx from engine emissions, yet none are designed to remove polycyclicaromatic hydrocarbons (PAHs). EnSolve?s approach is to develop a combined biological and mechanicalsystem that can remove PAHs from the scrubber system waste water. The results of the Phase I study confirmedthe biomechanical approach was effective in reducing PAHs at rates exceeding 99%.The broader impacts of this research will be to provide the maritime industry with a cost effective, reliable, and environmentally conscious treatment system for removing toxic substances from the world?s oceans. Ships will be required to either install scrubbing equipment or they will need to switch to more costly low sulfur fuels. A switch to low sulfur fuel would increase current fuel costs by over 88%. A commercial ship owner could realize annual savings of $2 million per vessel in fuel costs using a scrubber system compared with purchasing low sulfur fuel. An estimated 35,000 ships will be impacted by these regulations, yielding a market opportunity for the proposed scrubber water treatment system exceeding $5 billion. Other technologies under development utilize pure physical separation methods that transfer the contaminants from the scrubber water to another medium (i.e., filters) for disposal. Conversely, the proposed biological approach is a regenerative process that would significantly reduce landfill disposal, consumable, labor, and liability costs.
