Optimization Operation for Coking Process Based on Economic Performance Assessment

In coking process, the optimal operation cannot be ensured due to lack of performance assessment. This paper proposed an optimization operation method based on economic performance assessment for the coking process. Based on performance assessment with economic indicators and quality indicators, combined with the confidence level model, the expert rules were established to timely correct forecasting model of the economic indicators, or optimize the coke production process to achieve good operating conditions, while taking the economic indicators including coke yield and energy consumption as the goals, the cokes quality and mechanism conditions as constraints. The simulation shows that the method proposed in this paper can obviously increase coke yield and reduce energy consumption.
