Abstract

Coal is playing a major role as a reductant and as an energy source in the present world steel production due to its low cost and widespread distribution around the world. At the same time, being the largest contributor to global CO 2 emissions, coal faces significant environmental challenges in terms of air pollution and global warming. Hydrogen is a promising alternative for coal in lowering the steel industry’s CO 2 footprint, but the availability of green hydrogen is currently limited by its high production cost. This research study focuses on developing a pressure swing adsorption (PSA) technology that will allow for continued use of coal for a smooth transition towards green hydrogen-based steel production, by better utilisation of its by-product coke oven gas to produce high purity hydrogen. A generic, fast and robust simulation tool for simulating a variety of PSA processes considering both equilibrium and kinetic effects using a detailed non-isothermal and non-isobaric model is developed in the study. The adsorption equilibrium data required for the model are calculated from experimental results using the non-linear regression data fitting method. A series of rigorous parametric studies and breakthrough tests are performed using the developed mathematical model for better understanding of the effects of different factors on the PSA process performance. With the better understanding obtained from the above-mentioned parametric studies, the model is optimised by performing several simulation tests to achieve a high process performance in terms of purity and recovery of the H 2 product, productivity of the adsorbents and energy consumption for compression of gases. The optimised 14-step multi-bed PSA cycle developed in this study allows for an improved energy efficiency of coal usage by better utilisation of its by-product coke oven gas by converting it into valuable high purity (>99.999%) hydrogen product with a recovery of over 75%.

用变压吸附法从焦炉煤气中制氢-一种数学建模方法
煤炭由于其低廉的成本和广泛的分布在世界各地,在当今世界钢铁生产中作为还原剂和能源发挥着重要作用。与此同时,作为全球二氧化碳排放的最大贡献者,煤炭在空气污染和全球变暖方面面临着重大的环境挑战。在降低钢铁行业的二氧化碳足迹方面,氢是煤炭的一个有前途的替代品,但目前绿色氢的可用性受到其高生产成本的限制。这项研究的重点是开发一种变压吸附(PSA)技术,通过更好地利用其副产品焦炉煤气生产高纯度的氢气,使继续使用煤炭顺利过渡到绿色氢基钢铁生产。该研究开发了一种通用、快速和强大的模拟工具,用于模拟各种PSA过程,同时考虑平衡和动力学效应,使用详细的非等温和非等压模型。采用非线性回归数据拟合的方法,从实验结果中计算出模型所需的吸附平衡数据。使用开发的数学模型进行了一系列严格的参数研究和突破性测试,以更好地了解不同因素对PSA工艺性能的影响。从上述参数研究中获得更好的理解后,通过进行多次模拟试验对模型进行优化,以在h2产物的纯度和回收率、吸附剂的生产率和气体压缩能耗方面实现高工艺性能。本研究开发的优化的14步多床PSA循环通过更好地利用其副产品焦炉气,将其转化为有价值的高纯度(99.999%)氢产品,回收率超过75%,从而提高了煤炭使用的能源效率。
