Abstract

The invention provides an anhydrous treatment device for ether, which comprises a raw material ether heating tank, a crude effect separation column, a calandria condenser, a refined ether receiving tank and a tail gas absorption tank. The raw material ether heating tank is connected with a crude effect separation column, and the crude effect The outlet of the separation column is connected to the inlet of the calandria condenser, the outlet of the calandria condenser is connected to the refined ether receiving tank, and the exhaust gas outlet of the calandria condenser and the exhaust gas outlet of the refined ether receiving tank are respectively connected to the tail gas absorption liquid sealing tank . The raw material ether is heated and refluxed in the raw material ether heating tank to fully react with metal sodium to reduce the impurity water content in the raw material ether, and the coarse-step separation is carried out through a coarse-effect separation column. ether used.

Description

technical field [0001] The invention relates to an ether anhydrous treatment device. Background technique [0002] Since the manufacture of commercial diethyl ether has been disclosed in several research papers, it can be manufactured in a variety of ways. In addition, there are also a variety of processes that use diethyl ether as an intermediate compound. Due to the different operating conditions and the concentration of the liquid-gas phase, the combination of the ether process and the methanol process in the known technology is very complicated. [0003] Furthermore, the known art methods of forming ether are very energy intensive. Contents of the invention [0004] The purpose of the invention is to overcome the deficiencies in the prior art and provide an ether refining device. [0005] The purpose of the present invention is achieved through the following technical solutions: [0006] The ether anhydrous treatment device is characterized in that it includes a ra...
