Membrane distillation crystallization (MDC) is a promising hybrid separation technology that can play an important role in desalination, mineral recovery from liquid solution as well carbon dioxide fixation. MDC combines membrane and crystallizer into one integrated unit allows excellent of clean water high purity salt highly concentrated salts (i.e., brine), which otherwise detrimental when di...

Heat transfer coefficients in a continuous oscillatory baffled crystallizer (COBC) with nominal internal diameter of 15 mm have been determined as function flow and conditions typically used under processing conditions. Residence time distribution measurements show near-plug high Peclet numbers on the order 100–1000 s, although there was significant oscillation damping longer COBC setups. Very ...

Motivated by an important application in the chemical and pharmaceutical industries, we consider non-stationary growth of a polydisperse ensemble crystals continuous crystallizer. The mathematical model includes effects crystal nucleation growth, fines dissolution, mass influx withdrawal product crystals. steady- unsteady-state solutions kinetic balance equations are analytically derived. stead...

The rising trend towards continuous production in the field of small-scale crystallization has generated many creative concepts for apparatuses active pharmaceutical ingredients. One these promising is Slug Flow Crystallizer (SFC), which enables adjustment particle size distribution and achievement high yields through its alternating slug flow. To realize understand inside SFC, experimental eff...

In this paper, we focus on a batch protein crystallization process used to produce tetragonal hen egg white lysozyme crystals and present a comparative study of the performance of a model predictive control (MPC) strategy formulated to account for crystal shape and size distribution with conventional operating strategies used in industry, namely, constant temperature control (CTC) and constant ...

Coal-mine effluent treatment has the potential to both reduce environmental impact of and provide economic opportunities by recovering valuable minerals clean water. In this study, we modeled a novel process, which includes nanofiltration (NF), two-step crystallization, reverse osmosis (RO), electrodialysis (ED), multi-effect distillation (MED), NaCl crystallizer, performed techno-economic anal...
