规模小、分布散、产地偏远的煤层气资源给煤层气的转化和利用带来了巨大挑战。利用模块化装置，可以将此类煤层气资源的就近转化为容易运输的液态产品。从系统的角度研究模块化煤层气转化过程的集成优化以及模块化装置的最优配置对于提高资源利用效率和经济效益具有重要意义。本项目通过流程模拟建立煤层气转化过程模型，探索分布式煤层气转化系统中的设备共享以及与煤转化过程的互补方式，构建煤层气与煤的分布—集中式耦合转化系统的流程超结构。在此基础上，建立过程尺度与系统尺度耦合的多目标数学模型，通过定量优化，查清气源参数、经济参数变化对全局优化结果的影响规律，揭示模块化装置的配置机制以及资源利用效率与经济效益的协调优化机制。本项目融合了多学科知识，所得结果将进一步拓展过程集成优化理论，同时为煤层气的有效利用提供新思路，具有重大的理论意义和广阔的工业应用前景。

Small, distributed, and remote coalbed methane resources pose great challenges for coalbed methane conversion and utilization. Based on modular devices, such coalbed methane can be converted nearby into liquid products that are easy for transportation. It is of great significance to investigate the integration and optimization of coalbed methane conversion processes and the optimal allocation of modular devices for improving the resource utilization efficiency and the economic performance from a system perspective. Through process simulations, we build models of coalbed methane conversion processes to investigate the equipment sharing in the distributed coalbed methane conversion system and the complementary with the coal conversion process. A process superstructure for the coalbed methane and coal coupling conversion system with distributed-centralized networks is constructed. On this basis, a multi-objective mathematical model coupling process-scale and system-scale is formulated. The influences of gas resource and economic parameters on the global optimization results are investigated to reveal the mechanism of modular devices allocation and the coordinated optimization of the resource utilization efficiency and economic performance. The results of this project can further extend the process integration and optimization theory and present a new idea for effective utilization of coalbed methane. Therefore, this project is of great importance in both theory and industrial application.
