蒸馏装置分馏塔的技术改进

MAIN TECHNOLOGY IMPROVEMENT IN DISTILLATION COLUMNS OF CRUDE UNIT

列举了在国内外炼油蒸馏装置上，用高效规整填料Mellapak、Gempak改造不同生产方案的常压蒸馏塔、减压蒸馏塔的实例，有针对性的选择在常减压蒸馏装置上以不同的方法、不同的手段解决装置中存在的“瓶颈”以及在生产上存在的提高处理量、拔出率，改善质量、分离精度及节约能耗等一系列问题，以供提高我国炼油厂常减压蒸馏装置分馏塔的设计、改造及生产水平时借鉴。

?The structured packing has the advantage of increasing the capacity, raising the distillate amount, improving the product quality, reducing the overlap as well as energy conservation. Examples for improving the performance of atmospheric and vacuum distillation columns by using the structuredpackings in various production schemes are presented.
