Quantifying release rates during loss of primary containment

潜在危险流体的运输和储存几乎发生在所有工业加工设施中。一次密封损失(LOPC)是与每个处理步骤相关的风险，可以通过适当的工程和管理实践来减少，但不能完全消除。为了量化某一加工步骤造成的风险，重要的是能够准确地预测在发生密封损失时将释放的危险液体的数量及其在环境中的命运。普罗萨里斯咨询有限公司是一家总部位于新斯科舍省的咨询公司，专门从事流程行业损失预防和风险管理计划的开发，并帮助这些行业促进和维护强大的过程安全文化。目前，Prosaris正在开发一种软件工具，该工具将使对LOPC构成的风险的评估更加有效。该软件工具将提供已知工艺/工厂布局、操作条件、LOPC方案和关键工艺安全指标/指标之间的关键链接。该软件的一个关键组成部分将是它能够量化LOPC事件期间危险流体的释放率。该研究项目的目标是开发一种经过验证的建模方法和模拟环境，可用于量化LOPC场景中的释放率和数量。将使用目前可用的最佳做法和最先进的方法开发建模方法，并对应用程序进行具体修改。然后，该方法将被集成到模拟环境中，并通过与实验发布数据的比较来验证。通过与达尔豪西大学的合作，Prosaris将能够利用现有的过程建模和流体动力学模拟方面的专业知识。这将产生先进建模和模拟方法方面的新知识，将专门知识转移到私营部门，培训高素质的人员，并开发具有商业化潜力的技术。

The transportation and storage of potentially hazardous fluids occurs in nearly all industrial processingfacilities. Loss of primary containment (LOPC) is a risk associated with each processing step that can bereduced through proper engineering and management practices, but that cannot be eliminated completely. Toquantify the risk posed by a certain processing step, it is important to be able to accurately predict the quantityof hazardous fluids that would be released as well as their fate in the environment if a loss of containment wereto occur. Prosaris Consulting Ltd. is a Nova Scotia based consulting company that specializes in thedevelopment of loss prevention and risk management programs in the process industries, and in helping theseindustries promote and maintain a robust process safety culture. Currently, Prosaris is developing a softwaretool that will make the assessment of risks posed by LOPC more efficient. This software tool will provide thecritical link between the known process/plant layout, operating conditions, LOPC scenarios, and key processsafety metrics/indicators. One key component of this software will be its ability to quantify the release rates ofhazardous fluids during an LOPC event.The goal of this research project is to develop a validated modeling methodology and simulation environmentthat can be used to quantify release rates and quantities during LOPC scenarios. The modeling methodologywill be developed using currently available best practices and state-of-the-art methods, with specificmodifications for the application. The methodology will then be integrated into a simulation environment andvalidated through comparison with experimental release data. By partnering with Dalhousie University,Prosaris will be able to take advantage of the available expertise in process modeling and fluid dynamicssimulation. This will result in the generation of new knowledge in advanced modeling and simulation methods,the transfer of expertise to the private sector, the training of highly qualified personnel, and the development ofa technology with commercialization potential.
