Within the Carbon2Chem® project, new processes have been developed to valorize steel mill gases by producing methanol. This article compares the global warming impact of integrated steel and methanol production to the stand‐alone production of steel and methanol. In order to generate mass and energy balances of the cross‐industrial network, several simulation approaches were conducted, and two power sources investigated. In the case of a power mix in 2030, the conventional production of steel and methanol is favorable, and in the case of wind power, the integrated production of steel and methanol shows greater benefit. If an electricity mix with a carbon intensity of less than 0.23 kgCO2‐eq.kWh−1 electricity is used, the integrated production of steel and methanol has a lower global warming impact than stand‐alone steel and methanol production.

Carbon2Chem®项目中钢厂基于气体的甲醇生产的生命周期评估

在Carbon2Chem®项目中,已开发出新工艺以通过生产甲醇来增值钢铁厂气体。本文将钢铁和甲醇一体化生产与单独生产的钢铁和甲醇对全球变暖的影响进行了比较。为了产生跨工业网络的质量和能量平衡,进行了几种仿真方法,并研究了两种电源。在2030年实现电力混合的情况下,钢和甲醇的常规生产是有利的,而在风力发电的情况下,钢和甲醇的综合生产则显示出更大的收益。如果混合碳强度小于0.23 kg CO2当量的电。千瓦时-1 使用电力,钢和甲醇的综合生产对全球变暖的影响要比独立的钢和甲醇生产低。
