Description

Technical Field

[0001] The present invention relates to the technical field of epichlorohydrin production, and particularly to a residual pressure power generation device for a saponification reaction tower in epichlorohydrin production. Background Art

[0002] In the production processes of propylene oxide and epichlorohydrin, the common production methods are as follows: The main raw materials for the alcohol method to produce propylene oxide are chlorine, propylene, and lime milk. The production process is divided into three parts: namely, chlorohydrination, saponification, and refining. The production process of the double alcohol method is as follows: 1. Chlorohydrination is the process of reacting an olefin with chlorine dissolved in water in a tubular reactor to produce chlorohydrin; 2. Saponification is the process of reacting chlorohydrin with an alkali to produce an epoxide; 3. Refining is the process of purifying the epoxide.

[0003] In the prior art, after the saponification reaction process, the internal pressure in the saponification reactor is too high after the reaction is completed. The high-pressure gas is directly transmitted to the refining and purification reactor. The high-pressure gas often carries a certain amount of energy. Therefore, we set up a residual pressure power generation device to convert the residual pressure of the saponification reaction tower in epichlorohydrin production into electric energy to achieve energy recovery. Therefore, we propose a residual pressure power generation device for the saponification reaction tower in epichlorohydrin production. Summary of the Invention
