Abstract

The invention provides a diethyl ether water-free treatment device, which comprises a raw material diethyl ether heating tank, a coarse efficiency separation column, a calandria type condenser, a refined diethyl ether receiving tank and a tail gas adsorption tank, wherein the coarse efficiency separation column is connected on the raw material diethyl ether heating tank; the outlet of the coarse efficiency separation column is connected with the inlet of the calandria type condenser; the outlet of the calandria type condenser is connected with the refined diethyl ether receiving tank; and the tail gas outlet of the calandria type condenser and the tail gas outlet of the refined diethyl ether receiving tank are connected with a tail gas adsorption liquid seal tank respectively. Raw material diethyl ether is fully reacted with metal sodium in the raw material diethyl ether heating tank by heating and refluxing to reduce the content of impurity water in the raw material diethyl ether; coarse step separation is performed through coarse efficiency separation; and a diethyl ether raw material which meets the requirement of the preparation and the production of an MO source is obtained by the condensation of the calandria type condenser after the separation.

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...
