摘要:
针对我国目前上行制气能耗较大的现状，开发了上行制气采用增氧间歇式气化法工艺.以山东某有限公司技改前后为例对上行制气采用增氧间歇式气化的节能减排结果进行预测分析.技改前制气采用自然空气（79%的氮和21%的氧气）加入，技改后在满足(CO+H2)/N2的需要基础上，上行制气入炉蒸汽中加入含90%氧气和10%氮气量，直接弥补部分蒸汽分解时吸热反应的热量，使蒸汽长时间在高温条件下进行分解.预测结果表明：弥补了制气温度，提高蒸汽分解率和煤炭的利用效率，减少CO2、SO2的排放.
Abstract:
To solve the current problem of high energy consumption in the upstream gasification, we developed a technique of generating ammonia synthesis feed gas using intermittent gasification and oxygen enrichment during the process of upstream gas production. In order to predict the effects of oxygen gas on the upstream gasification via oxygen enrichment and gasification, a company in Sandong was taken as an example. Before technical transformation, natural gas air (79% nitrogen and 21% oxygen）was added in the gas making process. After the technical transformation, steam entering the gasifier including 90% oxygen and 10% nitrogen was used to meet the requirement of (CO+H2)/N2. Because the heat of steam decomposition in the endothermic reaction was made up, steam was decomposed in high temperature conditions for a long time. The results show that the rate of steam decomposition and the efficiency of coal utilization are improved, the emission of carbondioxide and sulfur dioxide is reduced.
