摘　　要：基于现有的一步法合成二甲醚分离工艺存在的种种缺陷,文章提出了一种新的分离工艺-"高压吸收、变压分离",并在此工艺的基础上,研发了新的分离设备-NS倾斜立体长条复合塔板(用于大气量、小液量的吸收塔板)和用于分离高纯度二甲醚的解吸精馏塔板,主要介绍塔板的特性、操作原理及工业应用。Based on the disadvantages of separation technology of one-step dimethyl ether synthesis, a new separation technology, called ＂high pressure absorption, pressure swing adsorption＂ was put forward. Ground on this technology, new separation devices-NS slant stereo strip combination tower tray which was used on more air less liquid absorption tower tray and desorption rectification tower tray which was used on high-purity dimethyl ether separation had already been studied and developed. The characteristics, operational principle and industry application were introduced mostly.
