| titleOfInvention | Acetic acid production method |
| abstract | A method for the production of acetic acid in acetic acid production equipment, the equipment comprising: a reactor; a first distillation column; a second distillation column; and a further purification unit, the method comprising: a reaction step of subjecting a material mixture comprising methanol, carbon monoxide, a catalyst and an iodide to a carbonylation reaction of methanol in the reactor to form acetic acid in a reaction mixture; a flash evaporation step of partially evaporating the reaction mixture to separate the reaction mixture into vapors and residual liquid components, where a portion of the vapors is introduced into the first distillation column as crude acetic acid stream; a first purification step of subjecting a crude acetic acid stream to distillation in the first distillation column to give a first acetic acid stream, the crude acetic acid stream containing the acetic acid formed in the reaction step, the first being acetic acid enriched acetic acid stream compared to crude acetic acid stream; a second purification step of subjecting the first acetic acid stream to distillation in the second distillation column as a dehydration column to give a second acetic acid stream enriched with acetic acid as compared to the first acetic acid stream; and a third purification step of subjecting an acetic acid stream to purification in the further purification unit while controlling a corrosive concentration of iodine in the acetic acid stream, which has a water concentration of 0.001 to 2 mass percent , which passes through the further purification unit at 100 ppm or less, to give a third acetic acid stream enriched with acetic acid compared to the second acetic acid stream. |
