摘要
Abstract
The coal to methanol unit of CHN Energy Yulin Chemical Co.,Ltd.uses coal as raw material and adopts coal water slurry gasification technology to produce crude gas.The crude gas undergoes sulfur tolerant shift to adjust the hydrogen carbon ratio,rectisol process to remove impurities and acidic gases,fine desulfurization in the fine desulfurization unit,and finally enters the methanol synthesis system to produce crude methanol products.In order to avoid deactivation of methanol synthesis catalysts and ensure normal production operation,the refined desulfurization unit uses domestically produced deep purification desulfurizer CNTS-11 for desulfurization under harsh conditions.The specific application of CNTS-11 desulfurizer was introduced,including loading,industrial operation data,strength after use,and sulfur capacity.After desulfurization,no sulfur-containing substances are detected in the syngas.The sulfur capacity of desulfurizer reaches 13.00%,which is 40%higher than similar domestic products,and there are no by-products produced during the process.关键词
