Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a reboiler for producing butyl acetate. Background Art

[0002] As the name implies, a reboiler is a device that vaporizes a liquid again. Its structure is similar to that of a condenser, but one is used to cool down, while a reboiler is used to heat up and vaporize. Reboilers are often used in conjunction with distillation towers: a reboiler is a special heat exchanger that can exchange heat and has a vaporization space. Reboilers are important heat exchange equipment in the field of petrochemicals. Its working principle is to use a heating medium, usually steam, to partially vaporize the medium in the reboiler, and to return it to the distillation tower through a cycle to provide energy for the separation process. Reboilers are important heat exchange equipment in the field of petrochemicals. Its working principle is to use a heating medium, usually steam, to partially vaporize the medium in the reboiler, and to return it to the distillation tower through a cycle to provide energy for the separation process. For the production process of acetate esters, the reboiler is a key reaction equipment. Acetic acid and alcohols are heated by steam under the catalysis of concentrated sulfuric acid, and fully react in the reboiler to form acetate esters. Then the vaporized acetate esters are continuously exported from the outlet pipeline to the distillation tower to complete the next purification process.

As the thickness of the dirt increases, the heat transfer efficiency decreases, which in turn leads to a decrease in the production efficiency of butyl acetate. To this end, we propose a reboiler for butyl acetate production. Utility Model Content
