Abstract
Most of chemical technologies are based on heterogeneous catalytic reactions (~80%). Model based tools used for design, control and monitoring of these processes require accurate kinetic parameters of these catalytic reactions. Laboratory measurements and on-line analysers can be used to monitor decreasing catalyst activity. However these measurements are affected by errors influencing the estimation of kinetic parameters. To increase the robustness and accuracy of the estimation we developed a method based on the integrated application of data reconciliation and flowsheeting simulation. The proposed technique is applied for an industrial hydrogenation system. The estimated reaction kinetic parameters can be utilized advanced process control of the process.
Highlights
Life time of catalyst is an important aspect in design of chemical technologies because the cost of catalsyt is 0.22 % of the cost of petrochemical products
To increase the robustness and accuracy of the estimation we developed a method based on the integrated application of data reconciliation and flowsheeting simulation
The life time of catalyst depends on the reaction, e.g. catalysts of polymerization reactions deactivate more rapidly than catalysts of methanol synthesis that can work for years without regeneration (Fig. 1)
