摘要

几十年来,氢一直被认为是未来的能源载体,由于新技术的复兴,炼油厂对氢的需求一直在上升。蒸汽甲烷重整法因其产氢效率高、成本低、环境足迹小而被广泛采用。然而,根据原料类型的不同,一个单位的氢气会产生9-10单位的二氧化碳,这些二氧化碳需要经过处理才能实现环境的可持续性。因此,优化氢气生产和二氧化碳捕获是解决这一问题的关键。利用Aspen HYSYS对蒸汽重整进行了预测和优化仿真研究。一个转换型反应器被用来开发这个基于仿真的模型。这项工作的主要目标是研究和优化氢气生产效率,同时通过改变工艺参数来减少二氧化碳。研究了不同产氢率下的CO2捕集效率,采用本研究提出的碳捕集系统,CO2吸收率最高可达98.8%。后来,阿斯彭能源分析工具揭示了能源和成本优化的潜在改进。

Optimization of Carbon Capture in Hydrogen Production via Steam Reforming: A Simulation-Based Case Study
Hydrogen has been considered a future energy carrier for decades and the demand for hydrogen in refineries is always upward due to the revival of new technologies. The steam methane reforming method is frequently employed because of its high hydrogen generation efficiency at a cheap cost and minimal environmental footprint. However, depending on the type of feedstock, one unit of hydrogen generates 9-10 units of CO2 that need to be treated for environmental sustainability. Therefore, the optimization of hydrogen production and CO2 capture is critical to address the issue. The simulation research was conducted to anticipate and optimize steam reforming using Aspen HYSYS. A conversion-type reactor was used to develop this simulation-based model. The primary goal of this work is to investigate and optimize hydrogen production efficiency while mitigating CO2 by varying process parameters. The CO2 capture efficiency was investigated at the different yields for hydrogen production and a maximum of 98.8% absorption of the CO2 was achieved using the carbon capture system proposed in the current study. Later, the Aspen Energy Analyzer tool revealed potential improvements for energy and cost optimization.
