A kind of intelligent reaction system and method for producing acetic acid by methanol carbonylation |
| abstract |
The invention provides an intelligent reaction system and method for producing acetic acid by methanol carbonylation. The intelligent reaction system for producing acetic acid by methanol carbonylation comprises: a carbonylation reaction kettle and a flash tank connected in sequence, and CO is simultaneously introduced into the carbonylation reaction kettle Carry out carbonylation reaction with methanol as raw material, and the carbonylation reaction kettle is filled with iridium-based catalyst; the carbonylation product from the carbonylation reaction kettle enters the flash tank to flash to obtain liquid phase components and gas phase components; gas phase components The acetic acid product is obtained after going to the gas phase rectification tower for rectification, the liquid phase components are returned to the carbonylation reactor to continue the reaction, and the acetic acid product that comes out after the gas phase rectification tower rectification goes to the product rectification tower for further rectification, The side-line extraction of the product after rectification also includes an intelligent control module, a big data analysis module and a drive module. The intelligent reaction system of the invention improves the quality of the acetic acid product by well recovering the iridium catalyst and further purifying the product. |
