Flocculation using selected cationic polymers reduces high‐risk host cell proteins in monoclonal antibody processes already during primary recovery

Biotechnology Progress, EarlyView.
Flocculation using cationic polymers leads to the creation of large floc complexes. Negative charged species like cells, cell debris, and negatively charged host cell impurities like host cell DNA and host cell proteins are trapped within the complex while the positively charged monoclonal antibody stays in solution.

A Partial Integral Equation (PIE) representation of coupled linear PDEs and scalable stability analysis using LMIs

at - Automatisierungstechnik, 2018
We present a new Partial Integral Equation (PIE) representation of Partial Differential Equations (PDEs) in which it is possible to use convex optimization to perform stability analysis with little or no conservatism.

Application of dynamic modelling and model‐based predictive control to enhance a cooling tower

The Canadian Journal of Chemical Engineering, EarlyView.
Model predictive control (MPC) applied to improve the operation of cooling towers. Abstract Model predictive control (MPC) differs from traditional feedback control by making predictions within a time horizon, providing better control actions for the process.

Coupled heat and mass transfer in reactive parallel‐plate flow: A perturbative Graetz model with modal symmetry and Arrhenius kinetics

The Canadian Journal of Chemical Engineering, EarlyView.
A perturbative Graetz model describes coupled heat and mass transfer in reactive Couette–Poiseuille flow between parallel plates. Viscous dissipation and heat of reaction produce a small temperature rise, which enhances Arrhenius reaction rates and modestly accelerates axial species conversion in the small‐Brinkman‐number regime.
