工業上常使用合成氣作為合成各種化學品的原料，且近年來綠色工業更加受到重視。為了使工業與環保均衡發展，本研究使用甲烷為原料，結合甲烷蒸氣重組與甲烷二氧化碳重組來生產合成氣，於獨立式系統完整考量生產過程的二氧化碳排放量，並透過系統優化使其近乎零排放，於此同時能有最佳的合成氣產能。
首先，本研究使用ASPEN Plus軟體來模擬生產合成氣製程，於穩態分析找到最佳操作條件。並使用Hammerstein model對動態系統進行系統鑑別，使用鑑別後的數學模式來設計控制器，期許系統不論是在設定點追蹤或干擾消除都能良好控制。

Syngas was a raw material for the synthesis of various chemicals in industry. In recent years, environmental issues is increasing, the balance of environment and industry becomes an important research topic. Our standalone design complete calculate of CO2 source in the production process. This work develops a dry (CO2) reformer, which is connected to the steam methane reformer unit, in order to consume carbon dioxide and unreacted methane. The purpose of this study is to get high syngas production and reduce emission of carbon dioxide.
In simulation part, this paper using ASPEN Plus to build syngas production process, to get optima operating parameters at steady state operating. Than using Hammerstein model identify dynamic system to get mathematical model of system. Finally, we use the mathematical model design controller to control our system.
