Abstract

Continuous crystallizers are known to exhibit sustained oscillations in solute concentration and size distribution. The usual stability analysis for mixed suspension, mixed product removal crystallizers is obscured by the use of dimensionless groups which not only depend upon the physical properties and control parameters in the problem but also depend upon the steady-state values of the state variables in the model. We introduce three new dimensionless groups for this problem which only depend upon physical properties and control parameters. These produce a stability plot which is simpler than previous attempts and lends itself to easy physical interpretation.

Integrating atmospheric models and measurements using passivity-based input observers
2019, Computers and Chemical Engineering
Atmospheric aerosol models simulate the concentration of gaseous pollutants and particulate matter in the atmosphere. These models include significant mismatch from the true atmosphere resulting from uncertainty in the inputs including meteorology and emission fields, extrapolation and simplification of experimentally-derived relationships for the process dynamics, and possibly un-accounted for processes. In this paper we estimate time-varying parameters that adjust uncertain dynamics to account for some of the model mismatch. We show how to design a passivity-based input observer (PBIO) using proportional feedback so that the model-measurement error exponentially decays. As a case study, the PBIO is applied to an atmospheric aerosol model simulating a uniformly mixed control volume to estimate the particulate matter emission rate. A relationship between known measurement noise and uncertainty in the PBIO-estimated unknown parameters is developed and illustrated in a case study that utilizes noisy measurements.
Dynamics and control of continuous reactive crystallization processes
2016, Journal of the Taiwan Institute of Chemical Engineers
Control of two continuous reactive crystallization processes, one for the production of barium sulfate and one for the production of L-glutamic acid, is investigated. In both processes, the crystal mass production rate and the volume mean size of the product are controlled by manipulating the reactant inlet volumetric flow rates and the holdup in the crystallizer. The reactant inlet concentration, nucleation rate, and temperature of the crystallizer are considered as disturbances. The control structures provide good performance for 10% changes in disturbance variables and setpoint changes. Furthermore, stability analysis is performed for both processes and operating regions where continuous oscillations in solute concentration and crystal size distribution can occur are identified.
Model-based control of particle properties in fluidised bed spray granulation

To the field of particulate processes it was transported by the work of Randolph and Larson [5] (with a focus on crystallisation); it was advertised and established in the field by D. Ramkrishna and co-workers [6]. In the literature, many successful applications of population balance modelling to particulate processes can be found, for instance in crystallisation [7–9], granulation [2,3,10–12], drying [13–15], or aerosol processes [16,17]. The main obstacle in the analysis and development of general control design methods for distributed parameter systems is the complex mathematical theory due to the infinite-dimensional character of the processes.
In this contribution different control approaches, ranging from standard linear control to non-linear model predictive control, are applied to fluidised bed spray granulation processes with internal and external product classification. These processes exhibit sustained non-linear oscillations in the particle property distribution, i.e. size distribution, that have negative influence on steady-state operation, for example a constant product mass flow with constant properties. The controllers are applied to stabilise these open-loop unstable steady-states.
Convergence results for continuous crystallizers
2013, IFAC Proceedings Volumes (IFAC-PapersOnline)
We derive global stability results for continuous crystallizers using convergence analysis. The sufficient condition for exponential stability is derived in the analytical expression. The analytical condition offers a lower bound of the nucleus size and an upper bound of the largest size that crystals can grow. These conditions ensure that all the trajectories of the crystallizer converge to a single trajectory which is not necessarily known beforehand.
Modeling and control of particulate processes and application to poly-silicon production
2012, Chemical Engineering Science
The population balance is used to develop a model and control system strategies for poly-silicon production in a fluidized bed reactor (FBR). An energy function is developed to study the stability property of particle growth. An analytical expression for the stationary distribution function is derived and compared with simulation and experimental results. The distribution is stable if the seed particles are sufficiently large. A novel discretization scheme solves the population balance equations. We demonstrate the equivalence of the continuous and discretized population balance. An equivalent stability condition for the discretized population balance is derived using Tellegen's theorem. Finally we design an inventory control system to control the particle size distribution. The zero-dynamics, i.e. the dynamics of particle phase, are asymptotically stable if the seed particles are sufficiently large.
Reducing the mean size of API crystals by continuous manufacturing with product classification and recycle
2010, Chemical Engineering Science
Citation Excerpt :
Many articles have addressed the issues of crystallizer stability and dynamics, covering a wide variety of cases including different kinetic models, fines destruction, classified product removal, and others as discussed by Lakatos et al. (2007). It has been shown for continuous isothermal crystallizers with primary nucleation, i.e., the system studied in this paper, that stable limit cycle oscillations can occur (Jerauld et al., 1983; Lakatos, 1996; Yin et al., 2003). In industrial batch or continuous crystallizations operated today the crystallizer slurry is filtered to separate the solid product from the mother liquor.
A continuous crystallization process is proposed that can produce active pharmaceutical ingredients with a small mean size and narrow distribution. The process flowsheet consists of a new product classifier configuration where the large crystals from the classifier are recycled to a dissolver along with the mother liquor from the filter. Crystallizer stability is explored and regions of sustained limit cycles are identified for the proposed kinetic models. Most industrial crystallizers are operated at low supersaturation; however, with this methodology the continuous crystallizer must be operated at high levels of supersaturation to promote nucleation and increase the number of small crystals in order to maintain a fixed desired production rate. The design and operating strategies presented can be implemented by simple modifications to most conventional continuous crystallization processes. This particle micronization technique may offer significant cost savings over other size reduction methods that utilize mechanical means.
