Department of Chemical Engineering and Chemistry

The Department of Chemical Engineering and Chemistry provides academic education and research at the highest international standards. Staff develop technology and scientific knowledge, thereby meeting long-term societal needs. Scientific curiosity and new insights in the department’s field are the points of departure for constant improvement of its three areas of expertise: molecular technology, materials technology and process technology. The department was founded in 1957, and has some 500 staff members, 13 full-time professors, 370 Bachelor’s and Master’s students, 20 Post-Master’s students and 170 doctoral candidates.

Project description

The vacant position is in the sub-group Interfaces with Mass Transfer (sim) from the research group Chemical Reactor Engineering (SCR) at the department of Chemical Engineering and Chemistry. The group aims to perform high-quality scientific and technological research in the chemical reactor engineering sciences with specific emphasis on the design, development and operation of structured multiphase reactors and rotating/spinning disc reactors. The research focuses on understanding and controlling the interaction of physical transport and reaction processes at all relevant time and length scales in the realization and testing of these chemical reactors for a wide range of applications and processes. The group's mission is to be among the world's top academic research groups in its field and to be leading in the development of novel technologies for new, highly efficient, inherently safe, and robust structured multiphase processing systems, which show the best productivity by a dedicated design of all relevant dimensions and optimum choice of dedicated operational procedures.

Project background

The processes of Chemical Vapor Deposition and Atomic Layer Deposition are vital for the fabrication of e.g. computer chips and solar cells. In both processes, fluids need to be evaporated with a chemical composition that becomes unstable above a certain temperature. This temperature can only be avoided by keeping the operating pressure and therefore the pressure drop low in the miniature evaporator. With new so-called contactless boiling techniques this can be achieved. In contactful boiling, on the other hand, the liquid rises through a porous wall by capillarity and evaporates on top in a gas flow passing by. Because of the complementary character of contactless and contactful boiling, both are studied in the present project.

In this project, funded by the Dutch Technology Foundation and a consortium of national and international industries, three PhD students and a post-doc will collaborate to study boiling and evaporation in miniature ducts. One of the PhD students will carry out experiments with advanced measuring techniques in two test set-ups, while two other PhD students will focus on numerical modeling. The present vacancy concerns the experimental work.

SUPERCRITICAL CO2 EXTRACTOR FOR SALE: 5L, 10L and 20L - 2,000 psi Complete Supercritical Fluid Extraction System - closed loop. Our systems are made at our fabrication shop in the state of Washington. Systems available: 5L, 10L, 20L, 100L, and larger custom. Typical build time is 2 weeks. This is not a Apeks Supercritical or Waters Supercritical CO2 Fluid Extraction System. We believe it is a better system, since we use 1/2 inch tubing for the CO2 flow, which is 4 times the flow rate of a Apeks, and up to 64 times the flow rate of a Waters system. We believe the result is faster processing time and better yield from increased exposure to CO2 solvent. Perfect for extraction of terpenes, trichomes, and Cannabinoids. Supercritical CO2 Fluid Extraction is a art, and the operator must have experience and training to obtain results. Go to website
