最近的页岩气革命为从甲烷中分布式制造关键的大宗化学品（如甲醇）提供了机会。然而，传统的甲烷制甲醇工艺是能源密集型的，这对盈利能力和可持续性产生了负面影响。我们报告了一种强化工艺配置，既具有经济吸引力，又具有环境可持续性。该流程图是使用基于构建块的表示和优化方法系统地发现的。新的工艺配置利用膜辅助反应分离，与传统配置相比，年总利润可高出190%。此外，它还减少了57%的二氧化碳当量温室气体排放。这种巨大的改进突出了基于积木式计算机辅助过程强化方法的优势。
The recent revolution in shale gas has presented opportunities for distributed manufacturing of key commodity chemicals, such as methanol, from methane. However, the conventional methane‐to‐methanol process is energy intensive which negatively affects the profitability and sustainability. We report an intensified process configuration that is both economically attractive and environmentally sustainable. This flowsheet is systematically discovered using the building block‐based representation and optimization methodology. The new process configuration utilizes membrane‐assisted reactive separations and can have as much as 190% higher total annual profit compared to a conventional configuration. Additionally, it has 57% less CO2‐equivalent greenhouse gas emission. Such drastic improvement highlights the advantages of building block‐based computer‐aided process intensification method.
