Title:
ETHYLENE GENERATING CRACKING FURNACE OPERATION ASSIST SYSTEM AND ETHYLENE PRODUCTION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/070804
Kind Code:
A1
Abstract:
An ethylene generating cracking furnace operation assist system (21) is provided with a storage server (22) and an analysis server (28). The analysis server (28) is provided with a surface temperature prediction unit (32), an input unit (44), and a case study unit (42). The surface temperature prediction unit (32) calculates the surface temperature of a radiation unit coil at an arbitrary future time using a coil surface temperature estimation model. The case study unit (42) performs, as a first function, a case study so as to maximize the amount of ethylene production in an operable period when a start time of decoking of the radiation unit coil has been preliminarily set through the input unit (44), and performs, as a second function, a case study so as to maximize the benefit until a limit time.
