Abstract
This paper analyzes the characteristics of a Natural Gas (NG)-based Methanol-Power Polygeneration System (MPPS). The structures and parameters of the polygeneration systems are investigated to explore the appropriate process for each polygeneration system. And some effective methods, such as exergy distribution analysis and energy-utilization diagrams (EUD) are adopted to investigate the performance & characteristic of the system. The results reveal that, MPPS adopted Partial Reforming and Partial Cycling synthesis (PR/PC) process can reach good performance, while MPPS exhibits poor performance when adopting Full Reforming and Once Through synthesis (FR/OT) process. Through further study with exergy analysis method, we find that the particular synthesis and separation properties of methanol lead to such difference. Therefore, the characteristics of chemical product should be important factors in the configuration and integration of polygeneration systems. The work of this paper is significant for the research and development of polygeneration system.

Summary
How to enhance the efficiency is an eternal topic for energy utilization system. To achieve this target, most efforts are focused on elevating the performance of components and system integration. Li H., et al proposed a new natural gas-based polygeneration system for power and methanol production [3]. Kreutz T. et al made techno-economic analysis of these hydrogen-electricity polygeneration systems [6]. Few studies paid attention to the impact on system characteristics brought by the internal property of chemical production process. The aims of this paper are: 1) to study the characteristics of different NG-based polygeneration systems; 2) to discuss the impacts on system characteristics brought by different chemical products; 3) to explore the appropriate process and parameters for different polygeneration systems
