在分析构成联供联产系统中关键技术的基础上,利用Aspen Plus软件对系统的单元操作过程进行了建模仿真工作。通过不同技术的组合,得到了二甲醚单产系统、二甲醚与电力的联产系统、煤与天然气联供的二甲醚电力联产系统,并通过模型的仿真计算,计算出各自系统中关键节点的物流和能流数据,为后续的3E研究提供了可靠的数据。
The advanced technologies of coal or NG gasification, the synthesis of DME in the liquid phase and IGCC are key to the in tegration involved in the standalonc system for DME, co-generation system for DME and electricity, and the co-feed ( from coal and NG) & co-production system for DME and electricity. Several unit process models have been built with the aid of the software Aspen Plus on the basis of analyzing those key technologies. Through the designs, simulations and calculations of the standalone system, cogeneration system and Co-Co system, simulation results concerning material flows and energy flows of the systems are obtained, which are the base for the subsequent study on energy, economy and environment.
