Integrated production tower of ethyl acetate

Abstract

The invention discloses an integrated production tower of ethyl acetate. The integrated production tower of the ethyl acetate comprises a tower body, a tower bottom reboiler and a tower top condenser,wherein the tower body is a cylindrical pressure container, and comprises a cylinder, an upper end socket and a lower end socket, and the tower body is divided into a tower bottom segment, a stripping segment, a reaction segment, an extraction segment, a rectification segment and a tower top segment by tower internals from bottom to top in sequence. The production tower is compact in equipment, the total occupied area is reduced by more than 60%, running energy consumption is low, and is saved by more than 40% compared with that of a conventional technology, and the device wastewater quantityis little, and is reduced by more than 80% compared with that of an existing technology.

Description

technical field [0001] The invention relates to an integrated preparation tower of ethyl acetate, which is a combined tower structure, specifically an integrated preparation that reacts to generate ethyl acetate and completes extraction and rectification in the same tower, and can directly take out the finished product tower equipment. Background technique [0002] Ethyl acetate is an important organic chemical product. At present, its main production method is continuous esterification with 98% concentrated sulfuric acid as a catalyst. The esterification reaction is carried out under the action to generate ethyl acetate and water, and the crude ester obtained by the reaction is refined through a rectification tower to obtain the final product. There are following problems in this mainstream ethyl acetate production process: (1) sulfuric acid is highly corrosive, many side reactions, by-products are difficult to handle, intermittent production requires system update after a...

AI Technical Summary

Problems solved by technology

There are following problems in this mainstream ethyl acetate production process: (1) sulfuric acid is highly corrosive, many side reactions, by-products are difficult to handle, intermittent production requires system update after a period of time; (2) needs thorough system cleaning, The process is interrupted, the system has a large amount of sewage, and the pressure on environmental protection is high; (3) The reaction, extraction and rectification in the process are completed separately in their own equipment, and the power consumption and steam consumption are large, which does not conform to the current green production concept
