Emission reduction becomes increasingly important for petroleum refineries nowadays. Cost-effective solution strategies require emission reductions to be addressed from the entire plant point of view, where emission source generations and reutilizations should be well balanced. This, however, presents a big challenge to refineries due to their large-scale complex manufacturing systems with hundreds of units and thousands of process streams. In this paper, a greedy concept of profitable emission reduction (PER) has been proposed, bearing merits of being economically attractive, environmentally benign, and technologically viable for emission reduction and control in petroleum refineries. To identify PER strategies, a methodology framework and a general plant-wide scheduling model have been developed. It couples generic production activities and characterizations of major air emissions from refineries, such as CO₂, volatile organic compounds (VOCs), nitrogen oxides (NO_X), and particulate matter (PM). A case study has demonstrated the efficacy of the PER concept and the developed methodologies.

全厂调度，以实现炼油厂的有利减排

对于当今的炼油厂而言，减少排放变得越来越重要。具有成本效益的解决方案策略要求从整个工厂的角度来解决减排问题，在这种观点下，排放源的产生和再利用应保持良好的平衡。然而，由于其具有数百个单元和数千个工艺流的大规模复杂的制造系统，这对精炼厂提出了巨大的挑战。在本文中，提出了贪婪的有利可图的减排量（PER）概念，具有在石油精炼厂的减排和控制上具有经济吸引力，环境友好和技术上可行的优点。为了确定PER策略，已经开发了方法框架和通用的全厂调度模型。参照图₂，挥发性有机化合物（VOC），氮氧化物（NO _X）和颗粒物（PM）。案例研究证明了PER概念和已开发方法的有效性。
