Hangzhou 310012) Abstract Jacketed vessel is the most commonly used chemical equipment in petrochemical industry. The jacket is divided into several subsections on the basis of the diathermanous area equidistribution and structure feature. The shell thickness of every pressure space is gained from strength calculation and stability calculation. Combined with the mixing medium characteristic parameters, the mixing scheme of reactor is given. The local stress calculation is done to verify the strength of jacket shell where the lug support is installed. The pressure test sequence and nondestructive detection method are given. The special and important aspects needing to be paid attention in the design of mixing reactor are described from several practical cases in detail, which are taken for reference and discussion.
