The Advantages of Acetic Acid Plant & Production Process
1) The stability of catalyst is better compared to other process.
2) The activity is better.
3) The selectivity is higher.
4) The process flow is short.
5) Less equipment is required.
6) The investment is lower.
7) The enginery consumption is lower.
SL Technology has rich experience in Acetic Acid plant design and construction of Acetic Acid plant for Acetic Acid production process. Welcome to contact us to get more detailed information of Acetic Acid plant design and Acetic Acid production process.
Acetic Acid production process of the Acetic Acid Plant starts from methanol and CO feedstock, which are continuously sent to the Reactor, at the presence of Rh catalyst and 3.0MPa(G), 180-220oC to synthesize acetic acid. The reaction solution is pressure relieved by flash valve before entering into the Flash Evaporator for vapor-liquid separation, from which the mother liquor at the bottom is pumped back to the Reactor for continuous conversion into acetic acid, while the vapor at the top is charged to the distillation system for purification to get acetic acid with concentration higher than 99.85%. By-products such as hydrogen, carbon dioxide, methane, propionic acid, hydrogen, methanol as well as the non-reacted carbon monoxide is collected to remove iodine substances before emission to the flare system.
