| Abstract: | 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. |
