NOVELTY - An industrial cracking furnace construction method involves establishing a value maximization model of industrial furnaces to optimize the cracking furnace operation. Predictive models are built based on the steam cracking of experimental data. The target cleavage product yield data is collected. The industrial cracking furnace pyrolysis product yield data is the calculated value of predictive models and industrial furnaces actual operation data, followed by establishing cracker maximize the value of the product model, cracking furnace operation data to calculate the cleavage products.    USE - Method for construction of industrial cracking furnace of a value-maximization model.    DETAILED DESCRIPTION - An industrial cracking furnace construction method involves establishing the value maximization model of industrial furnaces to optimize the cracking furnace operation. Predictive models are built based on the steam cracking of experimental data using mathematical modeling methods to establish industrial cracking furnace pyrolysis product yield prediction model represented by the equation as given in the specification according cracking feedstock properties. The target cleavage product yield data is collected by using feed rate, the amount of steam under the same conditions, in cracking furnace tube outlet temperature (COT), the normal operating range, and by adjusting the outlet temperature (COT) Acquisition Industrial furnaces actual operation target cleavage product yield data. The industrial cracking furnace pyrolysis product yield data is the calculated value of predictive models and industrial furnaces actual operation data, followed by establishing cracker maximize the value of the product model obtained after checking the forecast model cracker pyrolysis products to maximize the model input cleavage product price, cracking feedstock properties, cracking furnace operation data to calculate the cleavage products (petrochemicals) and the total value of maximum cracking furnace operating conditions.
