From Lab to Market: Evaluating Performance Metrics for Electrochemical Ammonia Synthesis versus Haber-Bosch

Ammonia (NH3) is a bulk commodity chemical known for its large production volumes and application in the global fertiliser industry, and is more recently being explored for its role as a sustainable energy vector. The industry standard ammonia production method is the century-old Haber-Bosch (HB) process, which is power by fossil fuels, and is...

From waste to products: Valorizing food side streams to recover natural products

This thesis presents novel ways of recovering of valuable compounds from food industry side streams. It does so via evaluating two case studies for the valorization of such streams. These types of streams are often referred to as waste and discarded. However, they are rich sources of nutraceuticals (e.g polyphenols), proteins and dietary fiber....

Conceptual Design and Assessment of Extractive Distillation Processes Using Deep Eutectic Solvents

Extractive distillation with organic solvents as entrainers is one of the most commonly used separation techniques for azeotropic mixtures in the chemical industry. To reduce the large energy requirements, and the secondary pollution problems, both of which are associated with the use of organic solvents, the search for alternative entrainers...

The SPPD-WRF framework: A novel and holistic methodology for strategical planning and process design of water resource factories

This paper guides decision making in more sustainable urban water management practices that feed into a circular economy by presenting a novel framework for conceptually designing and strategically planning wastewater treatment processes from a resource recovery perspective. Municipal wastewater cannot any longer be perceived as waste stream...

Designing reactive distillation processes with improved efficiency

In this dissertation a life-span inspired perspective is taken on the conceptual design of grassroots reactive distillation processes. Attention was paid to the economic performance of the process and to potential losses of valuable resources over the process life span. The research was cast in a set of goal-oriented engineering and specific...
