Abstract:

In this thesis novel configurations and operating strategies in the mixed suspension mixed product removal (MSMPR) crystalliser are investigated, aided by integrated process analytical technologies (PAT) and crystallisation informatics system (CryPRINS) tools. The MSMPR is an idealised crystalliser model that assumes: steady-state operation; well mixed suspension with no product classification, such that all volume elements contain a mixture of particles (small and large) and crystal size distribution (CSD) that is independent of location in the crystalliser and is identical of the product wit

Abstract:

Continuous hydrothermal flow synthesis (CHFS) can be used to produce nanoparticles that have a wide range of applications. In this work, population balance (PB) and computational fluid dynamics (CFD) technique were used to assist CHFS process development. Laboratory-scale experimental studies have been conducted to identify the key parameters required for the computational model. As a result, a PB model was developed to estimate the particle size distribution (PSD).

Civil Engineering<br>Ph.D.<br>Clean water is essential to life. Growth in world population, changing diets, and a warming climate are driving an increase in the demand for water. Better management of water resources will help prevent scarcity, but in order to fully meet the future demand for safe, clean drinking water, new water treatment technologies are needed. This dissertation investigates a technology which is not well understood; the combination of ozone and ultrasound as potentially an efficient technology.

Abstract:

State estimation is an integral part of modern control techniques, as it allows to characterize the state information of complex plants based on a limited number of measurements and the knowledge of the process model. The benefit is twofold: on one hand it has the potential to rationalize the number of measurements required to monitor the plant, thus reducing costs, on the other hand it enables to extract information about variables that have an effect on the system but would otherwise be inaccessible to direct measurement. The scope of this thesis is to design a state estimator for a tubu

The work of this dissertation is centered on two non-conventional synthetic approaches to ferromagnetic nanomaterials: high-throughput experimentation (HTE) (polyol process) and continuous flow (CF) synthesis (aqueous reduction and the polyol process). HTE was performed to investigate phase control between FexCo1-x and Co3-xFexOy. Exploration of synthesis limitations based on magnetic properties was achieved by reproducing Ms=210 emu/g. Morphological control of FexCo1-x alloy was achieved by formation of linear chains using an Hext. The final study of the FexCo1-x chains used DoE to determ

Abstract:

In this work process for the coupling reaction between a secondary chiral alcohol and a heterocyclic amine is studied. The chiral configuration must be inverted. The mesylate derivative of the alcohol is known to be unstable, so a continuous process with no isolation is developed for alcohol activation and amine coupling. This approach led to poor results in terms of yield and chiral purity. As an alternative approach, the Mitsunobu reaction is used. The application of flow chemistry to this reaction is promising since it uses highly energetic compounds and has a fast kinetic. Despite these pr

Currently, Taiwan has registered around eight thousand publishing houses with annual publication volumes over 40,000 new titles. Yet, there is to appear a standardized set of complete information on process flows for the publication industry to refer to and make comparisons with. Aiming at this deficiency and takin

Abstract:

[ENG] Global warming, caused mostly by the increasing of greenhouse gas concentrations in the atmosphere, has became one of the most serious environmental concerns. Between the major greenhouse gases, carbon dioxide had the most significant increase. Its high availability, non-flammability, low toxicity and independency from the food supply chain, makes CO2 utilization as a carbon feedstock an important topic from both industrial and academic perspectives. The aim of this work was to develop process intensification strategies for cyclic carbonate production from CO2 and epoxides. Cyclic carbon
