Title:
REACTION DEVICE, AND SYSTEM AND METHOD FOR SYNTHESIZING ACETIC ACID FROM CARBONYL
Document Type and Number:
WIPO Patent Application WO/2022/148162
Kind Code:
A1
Abstract:
The present invention provides a reaction device, comprising a reaction kettle, a circulating fluid stirring part, and a raw material gas distribution stirring part. The gas distribution stirring part comprises at least one gas distribution stirring unit; circulating fluid feed pipes penetrate through circulating fluid inlets and are communicated with a circulating fluid outlet; and a raw material gas feed pipe penetrates through a raw material gas inlet and is communicated with the gas distribution stirring part. The reaction device is used for synthesis of acetic acid from carbonyl, such that a shaft seal and a bottom fixed bearing are prevented from being easily damaged in an operation process during mechanical stirring, there is no movable sealing point, and safe and stable operation of a reaction system is guaranteed; appropriate internal component size and process operation indicators ensure the uniformity of liquid distribution and the stability of operating conditions in the operation process; and meanwhile, the at least one gas distribution stirring unit distributed in multiple layers and sequentially communicated enables gas in the reaction kettle to be distributed more uniformly, the gas-liquid two-phase mixing effect is improved, a reaction state in the system is optimized, a temperature difference in the reaction kettle is reduced, and side reactions are reduced.
