By a detailed comparison of various decarburization processes , The method of MDEA is chosen to absorb CO2 form shift gas. The rich fluid after goes through the thermal vapor for recycling, generating CO2 meanwhile. Based on the material balance and heat balance , the design of the main equipment, auxiliary equipment selection and facility layout are done. Then 40000Nm3 / h shift gas decarburization section in process design is completed. Additionally, the map of main equipment, process flow diagrams and plant layout are achieved. Finally, the economic, environmental and safety assessments of the whole process show that the process design achieves energy conservation and emission reduction requirements.
