摘要
NS倾斜长条立体复合塔板是吸取了New VST塔板的优点并优化其流体结构,将并流喷射结构和规整填料有机结合而开发的一种超大处理能力、高效率的新型立体塔板。介绍了NS倾斜长条立体复合塔板的结构、操作原理、特点及其在茂名石化公司和东方化工厂环氧乙烷精馏塔改造以及东明石化公司MTBE共沸塔的工业应用情况。工业应用数据表明,NS倾斜长条立体复合塔板能够显著提高产量和分离效率,是企业扩能改造和实现节能降耗的最优选择,具有更大的推广应用潜力。
NS stereo composite trays of tilt strip （NS SCTTS） is a new kind of stereo trays with larger throughput and high efficiency. This technology is an improvement of the New VST technology according to its flow structure,combining the cocurrent injection structure and structured packing effectively. The structures, operation principle and characters were introduced in the passage and its application on renovation of ethylene oxide refining tower in Maoming SINOPEC and Dongfang SINOPEC was described. Its industrial application implied that with NS SCTTS,the production and separation efficiency could be improved significantly. Obviously, it is the best choice for industrial renovation and energy saving, additionally, the potential application of this technology has a splendid future.
