摘要
我国工业副产气排放量大,在对环境造成污染的同时,副产气中H_(2)、CO等有效成分随排放而浪费。氢气既是重要的化工原料,也是无碳、高效的能源,用工业副产气制备或分离提纯氢气既减少资源浪费,又可减少CO_(2)排放。本文介绍了我国含氢工业副产气排放情况,详述了焦炉煤气制氢、炼厂副产气制氢、氯碱尾气制氢等三种典型工业副产气制氢工艺,对煤制氢、天然气制氢、甲醇制氢及三种典型工业副产气制氢工艺的成本和CO_(2)排放进行了计算和整理分析。文章指出,考虑二氧化碳排放和碳交易成本等因素,与煤制氢、天然气制氢、甲醇制氢和电解水制氢相比,现阶段下工业副产气制氢的综合成本优势更加明显。在碳中和背景下,工业副产气制氢是获取低碳氢气的有效和经济的途径,研究和开发工业副产气制氢技术,将为碳减排提供一条高效路径。
China’s industrial by-product gas emissions is large,which makes pollution to the environment,and meanwhile wastes the valuable resources such as H_(2) and CO.Hydrogen is an important chemical raw material,and also is a carbon-free and high-efficiency energy.The separation and purification of hydrogen from industrial by-product gas could reduce resources waste and CO_(2) emission.This article introduces the current emissions status of hydrogen-containing industrial by-product gas in China,three typical industrial hydrogen production processes,the calculation and analyses of their costs and CO_(2) emissions.These three typical processes are hydrogen production from Coke Oven Gas,refinery gas,and chlor-alkali emission gas.Taking into account factors such as carbon dioxide emissions and carbon transaction costs,the comprehensive cost advantage of hydrogen production from industrial by-product gas is more competitive.In the context of carbon neutrality,hydrogen production from industrial by-product gas is an effective and feasible way to obtain low-carbon hydrogen energy.Further researches and development of industrial byproduct gas hydrogen production technologies would provide an efficient way to reduce carbon emissions.
