镇海炼化国内首创“硫磺装置加氢催化剂预硫化尾气再脱硫”操作技术,该工艺使硫磺装置开工阶段二氧化硫排放浓度下降7倍以上。在Ⅶ硫磺装置开工过程中,镇海炼化把硫磺装置开工过程中加氢催化剂“预硫化”期间产生的废气改进吸收塔进行吸收净化,避免预硫化操作期间装置烟气中二氧化硫排放浓度超标。通
Zhenhai Refining & Chemical’s first domestic “sulfur plant hydrogenation catalyst pre-cure tail gas desulfurization ” operating technology, the process of sulfur dioxide plant starts to reduce the concentration of emission levels more than 7 times. In the process of starting the Ⅶ sulfur plant, Zhenhai Refining & Chemical will improve the absorber to purify and absorb the waste gas generated during the hydrogenation catalyst “presulfiding ” during the start-up of the sulfur plant to avoid excessive concentration of sulfur dioxide in the plant flue gas during the presulfiding operation . through

采用扫描电镜、傅里叶红外光谱和X射线衍射法研究了不同干燥方式对纤维形态及其超分子结构的影响.结果表明:与自然风干条件相比,强制干燥使得纤维变得更加光滑、挺硬,呈现扁平状,降低了纤维的润胀能力.不同的干燥方式不会改变纤维的晶型结构,但对不同模式的氢键的含量却产生了明显影响.与自然风干的纤维相比,强制干燥后纤维分子间氢键O(6)H…O(3′)含量明显增加了19.41％,而分子内氢键O(2)H…O(6)
