In order to utilize a wider range of low-grade syngas, the syngas biomethanation was studied in this work with respect gas–liquid mass transfer and reactor start-up strategy. Two reactors, continuous stirred tank (CSTR) bubble column gas recirculation (BCR-C), were used experiment by feeding an artificial 20% H2, 50% CO, 30% CO2 into reactors at 55 °C. The results showed that CH4 productivity s...

The proteomics analysis could contribute to better understand about metabolic pathways in anaerobic digestion community because it still as a “black-box” process. This study aimed analyze the proteins of co-digestion performed reactors containing residues from first and second generation ethanol production. Metaproteomics was carried out for three types samples: sludge without substrate (SI), s...

In this paper, Particle Filter algorithm has been employed for estimating the states namely concentration and temperature of a Continuous Stirred Tank Reactor (CSTR) and simulation results are presented. The propagation of particles through the nonlinear system model for the state estimation has been discussed. The states of the system are estimated by using the Particle Filter algorithm under ...

In this work, non-linear control of CSTR for reversible reaction is carried out using Fuzzy Logic as design tool. The Model Reference Adaptive Control approach in used to design Fuzzy controller. The idea is to have a control system that will be able to achieve improvement in the level of conversion and to be able to track set point change and reject load disturbance. We use PID control scheme ...

A specific class of positive systems is considered, where the system structure allows control of the distribution of “mass” in the system. Some robustness properties of the controller are pointed out, and the applicability of the model class is discussed. An example considering a CSTR modeled by massand energy balances illustrates the presented concepts.

This paper shows that any thermodynamic potential fulfilling some thermodynamic stability criterion (e.g. the chemical affinity or the ectropy) can be used as a potential function for the dissipative (pseudo) Port Hamiltonian formulation of the non isothermal Continuous Stirred Tank Reactor (CSTR) model. Besides Brayton-Moser formulation is used to obtain some dissipative Port Hamiltonian repre...

Forces oscillations introduced in the input flow rate of non flat continuous stirred-tank reactors (CSTR with 3 independent species) are shown to result in an averaged flat system with linearizing output independent of the special form of the kinetics laws.

The paper addresses a case study of robust stabilization of a continuous stirred tank reactor using robust model-based predictive control with constrained input variables. One exothermic reaction runs in the reaction mixture and the reactor is modelled in the form of an uncertain polytopic system. The control approach is based on solution of a set of linear matrix inequalities. This formulation...
