Abstract Raw material selection is very important in industrial production, and technical, environmentally sustainable and economic criteria must be taken into account. Purified flue gas and useless polyethylene waste are proposed for use as sustainable raw materials, thus minimizing wastes and emissions and protecting the environment. The use of flue gas in this way could reduce CO2 emissions by 1.9 106 kmol/a. This study uses an applied intelligent calculation technique to analyze the replacement of natural gas with wastes. This technique includes applied upgrades and offers environmental benefits: • modification of existing processes with well-known technology, using wastes as raw materials • predicting constant applied assumptions of industrial production within effective process units with sensitivity analyses using the Aspen Plus simulator • using mathematical calculations to determine optimal and sustainable production rates and energy and raw material consumption. The constant applied assumptions provide measurable effects on optimal sustainable product production with the same quality. This technique was tested on an industrial methanol process, replacing natural gas with purified flue gas and useless polyethylene waste. By determining constant applied production assumptions within effective reactors, a hypothetical plant could generate an additional profit of 3.8 MEUR/a.

应用智能计算技术改造现有工艺，以烟气和聚乙烯废料为原料

摘要 原材料选择在工业生产中非常重要，必须考虑技术、环境可持续和经济标准。建议将净化的烟气和无用的聚乙烯废物用作可持续原材料，从而最大限度地减少废物和排放并保护环境。以这种方式使用烟气可以减少 1.9 106 kmol/a 的 CO2 排放量。本研究使用应用智能计算技术来分析用废物替代天然气的情况。该技术包括应用升级并提供环境效益： • 使用众所周知的技术修改现有工艺，使用废物作为原材料 • 通过使用 Aspen Plus 模拟器的敏感性分析，预测有效工艺单元内工业生产的持续应用假设 • 使用数学计算来确定最佳和可持续的生产率以及能源和原材料消耗。不断应用的假设为具有相同质量的最佳可持续产品生产提供了可衡量的影响。该技术在工业甲醇工艺中进行了测试，用纯化的烟道气和无用的聚乙烯废料代替天然气。通过确定有效反应堆内恒定应用的生产假设，假设工厂可以产生 3.8 MEUR/a 的额外利润。不断应用的假设为具有相同质量的最佳可持续产品生产提供了可衡量的影响。该技术在工业甲醇工艺中进行了测试，用纯化的烟道气和无用的聚乙烯废料代替天然气。通过确定有效反应堆内恒定应用的生产假设，假设工厂可以产生 3.8 MEUR/a 的额外利润。不断应用的假设为具有相同质量的最佳可持续产品生产提供了可衡量的影响。该技术在工业甲醇工艺中进行了测试，用纯化的烟道气和无用的聚乙烯废料代替天然气。通过确定有效反应堆内恒定应用的生产假设，假设工厂可以产生 3.8 MEUR/a 的额外利润。
