Dynamic Simulation of Methanol Synthesis Loop under Abnormal Conditions

Key Words:dynamic simulation; methanol synthesis; fault diagnosis

Abstract:As the core component of methanol production, methanol synthesis takes place in a loop where hydrogen, carbon monoxide and carbon dioxide are converted to methanol per pass through the methanol reactor. Its nonlinear mathematic model is built in this paper, based on partial data from literatures. The research focuses on four types of unit: methanol reactor, methanol separator, synthesis gas compressor and heat exchanger, and performs dynamic simulation under fault conditions. Results show that the model has enough precision to meet fault simulation requirements. This work establishes the research foundation for future quantitative fault modeling, diagnosis algorithm selection and fault effect analysis.
