Title:
THERMAL CRACKING APPARATUS AND THERMAL CRACKING GAS ENERGY RECOVERY METHOD
Document Type and Number:
WIPO Patent Application WO/2023/226390
Kind Code:
A1
Abstract:
Disclosed in the present application are a thermal cracking apparatus and a thermal cracking gas energy recovery method. The thermal cracking apparatus comprises a thermal cracking furnace and a plurality of cracking gas thermal energy recovery systems; each cracking gas thermal energy recovery system comprises a plurality of heat exchangers, and the cracking gas thermal energy recovery systems each comprise the heat exchangers which are different in terms of the numbers and/or types; and the thermal cracking furnace is provided with a plurality of furnace chambers, each furnace chamber is internally provided with at least one independent cracking channel, and cracking gas outlets of one or more cracking channels are in communication with a cracking gas inlet of one of the cracking gas thermal energy recovery systems. By means of the thermal cracking apparatus, a plurality of different raw materials being cracked in one cracking furnace can be satisfied, such that flexible combination and switching of the cracking raw materials is realized, and thus cracking gas energy is greatly recovered and utilized.
