Alcohol oxidation: 95% of the raw alcohol and 76% of the alcohol recovered in the workshop are mixed in the mixing tank ratio into 84 0.5% dilute alcohol, the alcohol ingredient is heated by evaporation pot into the oxidation furnace, and has reaction to generate acetaldehyde gas at 555 5 ℃ high temperature and under the catalysis of electrolytic silver. The reaction gas mixture enters into the absorption tower after being condensed, and is diluted with about 8-10% of dilute acetaldehyde after being absorbed by water once. Acetaldehyde refining and alcohol recovery: dilute acetaldehyde is sent into the acetaldehyde distillation column for pressure distillation; control the top temperature at 45 2 ℃ and pressure at 0.15Mpa; the tower gives pure acetaldehyde. Bottoms temperature should be controlled at 121 3 C, the material is pressurized into the alcohol recovery column distillation with the tower temperature being controlled at 90 5 C; the tower top finally produce about 76% alcohol to be used as the ingredient of the alcohol oxidation process; control the bottoms temperature at 110 3 ℃, and the waste water is discharged through the tower kettle. Acetaldehyde oxidation: Acetaldehyde enters into the oxidation tower through the action of the pressure pump; it has reaction with the compressed air at a temperature of 50 ~ 80 ℃, pressure 0.20 ~ 0.22Mpa and under a certain amount of manganese acetate to generate crude acetic acid. The crude acetic acid is discharged from the upper discharge port of the oxidation tower to the crude acetic acid storage tank; the unreacted acetaldehyde is condensed and separated from the top of the tower through the condenser, the liquid is refluxed to the bottom of the oxidation tower, and the exhaust gas is further absorbed into the rear of the oxidation tower by the bubbling absorber into the atmosphere. Acetic acid refinement: The crude acetic acid is evaporated by the high-boiling pot to separate the manganese acetate from the heavy component, the temperature of the high-boiling evaporation pot is controlled at 120 2 ℃, and the manganese acetate at the bottom of the high-boiling pot is discharged into the manganese circulation tank of the acetaldehyde oxidation process for recycling. The light fraction in the top enters into the concentration distillation column, and the bottoms temperature is controlled at 123 3 C; acetic acid inside the tower is continuously and quantitatively discharged into the finished product evaporating pot and further distilled and condensed into acetate at 120 2 ℃ into the finished product metering tank. After qualification, it is sent into the finished product pot. The temperature of the top of the tower is controlled at 100 2 ℃. The dilute acid produced at the top of the tower enters into the measuring tank and is put into the dilute acid tank after measurement. Production route includes BP Cativa process and Celaness AOPlus process. BP Cativa process BP is the worlds largest provider of acetic acid, and 70% of the worlds acetic acid production uses BP technology. BP introduced the Cativa technology patent in 1996. The Cativa process uses a new iridium-based catalyst system and uses a variety of new additives such as rhenium, ruthenium and osmium. The iridium catalyst system has higher activity than rhodium catalysts with few by-products and operates at lower water concentrations (less than 5%), which greatly improves traditional methanol carbonylation, cuts production costs by up to 30%, and reduces expansion costs by 50%. In addition, due to the decrease of water concentration, the CO utilization efficiency is increased and the steam consumption is reduced. Celanese AOPlus process Celanese is also one of the largest acetic acid producers in the world. In 1978, the Hurst-Celanese Company (now Celanese) commissioned a Monsanto acetic acid plant at Lake Clare in the U.S. state of Texas. In 1980, Celanese Corporation introduced the AOPlus method (acid optimization method) technology patents, greatly improving the Monsanto process. The AOPlus process increases the rhodium catalyst stability by adding high concentrations of inorganic iodine (mainly lithium iodide), and the water concentration in the reactor after the addition of lithium iodide and methyl iodide.
