Title:
EXTERNAL MICRO-INTERFACE UNIT ENHANCED REACTION SYSTEM AND PROCESS FOR PRODUCTION OF PTA FROM PX
Document Type and Number:
WIPO Patent Application WO/2021/196383
Kind Code:
A1
Abstract:
An external micro-interface unit enhanced reaction system and process for production of PTA from PX. The system comprises a reactor, a first micro-interface generator (17), and a second micro-interface generator (18); the reactor comprises a housing (10), a feed port (22), a first baffle plate (13), a second baffle plate (14), and a circulating heat exchange device partially disposed outside the housing (10); a first reaction zone (11) is formed between the inner wall of one side of the housing (10) and the first baffle plate (13), a first overflow zone (15) is formed between the first baffle plate (13) and the second baffle plate (14), and the first overflow zone (15) is communicated with the first reaction zone (11); a second overflow zone (16) is formed between the second baffle plate (14) and the inner wall of the other side of the housing (10), and a second reaction zone (12) is formed at the bottom of the reactor; the first micro-interface generator (17) is separately connected to the feed port (22) and the circulating heat exchange device, the second micro-interface generator (18) is disposed at the bottom of the second reaction zone (12), and both the first micro-interface generator (17) and the second micro-interface generator (18) are used for breaking raw material air into micro-bubbles.
