Facing energy transition and carbon mitigation is the subject of different sectors from energy production and industries to transportation and building constructions. This study focuses on industrial decarbonization and investigates carbon dioxide (CO2) emissions from different petro-/chemical plants. For this research project, the emission rate and CO2 stream purity of various petro-/chemical sub-sectors were listed to find the low-hanging fruit options for decarbonization. Then, the processes are categorized and described, deriving the most important parameters from different literature to generate an essential dataset for each product. This paper includes the main achievements over ethylene-oxide and ammonia production and investigates the CO2 emission sources at the related processes, it also introduces novel decarbonization approaches.EPOC projec
