METHOD AND APPARATUS FOR SUPPORTING OPERATION OF MULTITUBULAR REACTOR OR PREPARATION ACTION THEREOF

Document Type and Number:

WIPO Patent Application WO/2023/157699

Kind Code:

A1

Abstract:

This method for supporting operation of a multitubular reactor or a preparation action thereof including a plurality of reaction tubes configured to produce at least one of unsaturated aldehyde and unsaturated carboxylic acid by oxidation reaction using a catalyst, or a conjugated diene by oxidative dehydrogenation reaction includes making a computer device execute: an acquisition step for acquiring reaction tube information regarding a part of a plurality of reaction tubes included in the multitubular reactor; and an output step for outputting supporting information for supporting operation of the multitubular reactor or a preparation action thereof by performing statistical processing of the reaction tube information. The reaction tube information includes real machine temperature information related to the temperature in the reaction tube at the start of the oxidation reaction or the oxidative dehydrogenation reaction, at the end thereof, during steady-state operation, at a setting change of control factors, or during air treatment. The supporting information includes comparison information between the real machine temperature information and intra-tube temperature information in a reactor different from the multitubular reactor.
