Methanation Unit Process Configuration Optimization Analysis Of CPI Huocheng SNG

Coal chemical technology that taking coal as raw material and new energy system will increasingly play an important role on the energy structure in the future. Methane as one of the important raw material in C1 chemical industry will influence the energy structure adjustment of the whole world. At the same time it also positively affects improvement of environment and progress of human society. The innovation and optimization of methane process will play an important role in the production of coal chemical industry.This article mainly focuses on process simulation, equipment selection, and economic analysis of the optimized methane process. Through research and analysis of the Topsoe high temperature methanation process, a simulation model is established by using the tools of advanced chemical process simulation software in order to verify the model of CPI project. While completing the simulation, the optimized methane process system model is established based on this model. The final simulation outcome is accordance with the licensor process operation conditions. Therefore it illustrates the feasibility of the optimized process and it can be used in subsequent process optimization research. In addition, based on the process of this simulation, the process optimization scheme will be researched by adjusting the utility conditions. The optimization process with economic benefit will be established and will be applied to the plant operation.According to the established simulation process, the economic benefit is calculated by comprehensive comparing the operation costs, such as the equipment investment, power consumption, and water consumption.
