Abstract: This paper mainly introduces advanced process control and real-time optimization technology development, research and application of characteristic of cracker in ethylene based on online NIR analysis of ethylene .NIR Analyzer configuration requirements and functions is described in detail. APC and RTO implementation of typical control schemes in cracking furnace are described in detail. The operation interface of the program is explained. It is described the requirements of oil POINA model. Finally,It is introduced each external conditions which the APC control is need.
