While energy use reduction projects in retrofit are often difficult to justify economically for industrial processes on a stand-alone basis, there is a significant opportunity when these projects are made in conjunction with major projects and process modernizations. Such is the case for biorefinery retrofit into pulp and paper mills. With biorefinery projects, there can be an important opportunity for energy “re-profiling” and improved site-wide energy efficiency, and at the same time, for increasing the overall economic profitability of the larger project. To address energy management in existing and new industrial processes, in general and for the specific case of biorefinery implementation, we have developed a breakthrough practical methodology called the Bridge Method that considers complex issues such as retrofit situations, site-wide energy integration, and utility/cogeneration systems. The fundamental principle behind the Bridge Method is that in industrial processes, heat cascades through heat exchangers and process operations from hot to ambient. In the Bridge Method, this feature is reflected in the Energy Transfer Diagram (ETD) for the analysis of process operations and heat exchange networks in order to reduce external energy usage. A sequential design decision-making framework has been developed for the systematic application of the Bridge Method in the industrial context. The framework considers a user-interactive decision-making approach, where design calculations are made automatically and open-ended design decisions are taken at different points sequentially in the design process, leading to a practical set of recommendations for plant-wide energy optimization. Improvements in the Bridge Method Framework are necessary to arrive at a practical method suitable for site-wide energy analysis in industry, incorporating state-of-the-art systems engineering and digitalization techniques the objective of this proposal. The goals of this Discovery Grant proposal are to improve the decision-making framework for site-wide energy analysis based on the Bridge Method, and render the method practical, robust and suitable for industrial application. The potential energy integration opportunity of new biorefinery processes into existing industrial sites is considerable and if the Bridge Method is deployed and applied in the Canadian forest products industry in the coming years, it has the potential to result in attractive economic returns, significant reductions in greenhouse gas emissions, as well as improved competitive position of Canada's emerging bioeconomy for the longer-term.

虽然改造中的能源使用减少项目通常很难在独立的基础上经济地证明工业流程的合理性，但当这些项目与重大项目和流程现代化结合起来时，就会存在重大机会，生物炼制厂改造就是如此。纸浆和造纸厂。生物精炼项目可以为能源“重新配置”和提高整个工厂的能源效率提供重要机会，同时提高大型项目的整体经济盈利能力。现有的管理和新的工业流程，总体而言以及针对生物精炼厂实施的具体情况，我们开发了一种突破性的实用方法，称为“桥梁方法”，该方法考虑了复杂的问题，例如改造情况、全厂能源整合和公用设施/热电联产系统。 桥法背后的基本原理是，在工业过程中，热量通过热交换器和过程操作从热到环境进行级联。在桥法中，这一特征反映在用于分析过程操作和环境的能量传递图（ETD）中。为了减少外部能源使用，我们开发了一个顺序设计决策框架，用于桥接法在工业环境中的系统应用，该框架考虑了一种用户交互式决策方法，其中设计计算是。自动做出开放式设计决策在设计过程中的不同点按顺序采取，从而得出一套针对全厂能源优化的实用建议，需要对桥法框架进行改进，以得出适合工业现场能源分析的实用方法，其中包括。最先进的系统工程和数字化技术是本提案的目标。 该发现资助提案的目标是改进基于桥接法的全场能源分析的决策框架，并使该方法实用、稳健且适合工业应用，将新的生物炼制工艺的潜在能源整合机会。现有的工业用地相当可观，如果未来几年在加拿大林产品行业部署和应用桥梁方法，它有可能带来可观的经济回报，显着减少温室气体排放，并提高竞争地位加拿大新兴的生物经济更长期的。
