Abstract
In this study, a new process with the aim of producing green synthesis gas (syngas) with high thermodynamic energy and exergy efficiency is presented. This process consists of four units including a water electrolysis unit (WEU), an Allam power cycle (APC), a Water/Ammonia power cycle (WAPC), and an organic Rankine cycle (ORC). The process was simulated, and the results showed that the overall efficiency of energy and exergy is 60.44% and 63.22%, respectively. It was also found that for this novel process, total exergy destruction is 10.97 MJ/kgsyngas, whereas APC, ORC, WAPC, and WEU units have 66%, 4%, 2%, and 28% share in exergy destruction, respectively. Additionally, the energy analysis results showed that APC, ORC, WAPC, and WEU units have an energy efficiency of 19.07%, 17.76%, 14.48%, and 83.22% respectively. According to the environmental assessment, the direct and indirect emission of carbon dioxide in the proposed process is zero. In this respect, the proposed process has a significant advantage compared to other syngas production methods.
