The chemical reactor is a fairly complex industrial system and presents several variables, so an online identification of the process parameters is required to adjust the process control loops. This paper deals with continuous time and delay system identification of the chemical reactor. The identification of linear and multi-input multi-output (MIMO) system is based firstly, on the Least Square/...
Because of the dependence of the parameters in the chemical reactor industries to the raw material used in processes, an online identification of the process parameters is necessary to adjust the process control loops. This paper deals with continuous time and delay system identification of the chemical reactor. The identification of linear and single input-single output (SISO) system is based on...
This work deals with the physical modeling of the phosphoric unit in the Tunisian Chemical Group (TCG). The process is consisting of a continuous reactor and a rotary filter. This study focuses on the different physical laws involved in the filtration step and the attack step combined with different actuators models in order to get a simulator of the global process. In control, this system is Multiple...
This work deals with the modeling of a chemical reactor on the Chemical Tunisian Group (CTG) factory of “Skhira” based on physical equations. Diversification of phosphate quality has a great effect on the viscosity of the slurry and hence on the level of the reactor, which brings us to model the system to make the appropriate tests. Modeling the tank attack is mainly based on physical laws as well...
This work was done in Tunisian Chemical Group (TCG) factory Skhira producing phosphoric acid. It involves studying the filtration of slurry of phosphoric acid manufacture in second stage. This study will focus on the physical modeling of filtration phase and the setpoint is optimization under constraints which takes into account the different functional requirements of the system. The optimized parameters...
