Mandalahalli, M.M. (author)
Bubbly flows are ubiquitously found in natural systems and are widely used in (bio)-chemical and energy-producing processes. A variety of design options, ease of maintenance, and a large operability window make bubble columns a commonplace across industries, ranging from oil processing to biotechnology and electrolyzers. Despite their wide...

Over the years, various technologies have been developed to produce and separate advanced biomolecules. These technologies range from complex terpenoids for pharmaceuticals and flavors to commodity chemicals and fuels via the fermentative route. These compounds are often poorly water soluble, phase splitting organic compounds or inhibitory and...

There is an increasing demand from the petroleum industry for high accuracy subsea multiphase flowmeters to make the development of difficult to access deep water and ultra-deep water fields economically viable. Nuclear Magnetic Resonance (NMR) is a very powerful measuring principle, and is one of the few techniques considered to be capable of...

The broth in industrial scale fermentors may contain significant gradients in, for example, substrate concentration, dissolved oxygen and shear rates. From the perspective of microbes in this fermentor, these gradients translate to temporal variations in their environment that may affect their metabolic response. As a result, there may be...

The current understanding of the transport phenomena involved in the operation of industrial fermenters is not sufficient. This is reflected by the limitations seen in their design and operation. A better insight in the local processes taking place (hydrodynamics, gas dispersion, mixing, microbial kinetics) is required to be able to make a step...

Provision of clean drinking water to poor can prevent a large number of deaths and illnesses amongst children around the world. In 2010, about 0.75 million child deaths were caused due to diarrhea, and a further 22.5 million years of life were lost due to ill-health, disability or early death caused by unimproved water and inadequate sanitation...

High speed X-ray tomography is a promising tool to visualize the time-resolved gas distribution for fluidized beds. The tomography unit at Delft University of Technology is composed of three X-ray tubes and three double-layer detector arrays. The X-ray tubes are places at 120? around the fluidized bed. The detector arrays are placed opposite to...

Van Campen, L.J.A.M. (author)
Separation of oil and water is an essential step in the treatment of the production streams from fossil oil wells. Settling by gravity is a robust though voluminous process and therewith expensive method at remote locations, leading to a need for smaller separation equipment. In this thesis, we describe the research performed on the development...

transportation facilities. In an offshore oil and gas production facility, pipeline-riser systems are required to transport two-phase hydrocarbons from subsurface oil and gas wells to a central production platform. Severe slugs reaching several thousands pipe diameters may occur when transporting gas and liquid in these pipeline-riser systems....

The vertical rod/tube bundle geometry has a wide variety of industrial applications. Typical examples are the core of light water nuclear reactors (LWR) and vertical tube steam generators. In the core of a LWR, primarily coolant flows upward but their also exist a flow in lateral direction, called crossflow, in the gaps in between the sub...

Gryzlov, A.N. (author)
The growing demand for hydrocarbon production has resulted into improved oilfield management with various control and optimization strategies. These strategies in turn strongly rely on the efficiency of downhole equipment which is used to obtain real-time oil and gas production rates with sufficient spatial and temporal resolution. In particular...

Kadri, U. (author)
Long liquid slugs reaching several hundreds pipe diameter may appear when transporting gas and liquid in horizontal and near horizontal pipes. The long slugs cause system vibration and separation difficulties that may lead to operational failures. Identifying and predicting the time and length scales of slugging is important for gas and oil...

Van 't Westende, J.M.C. (author)
Annular-dispersed gas-liquid pipe-flows are commonly encountered in many industrial applications, and have already been studied for many decades. However, due to the great complexity of this type of flow, there are still many phenomena that are poorly understood. The aim of this thesis is to shed more light on some of these processes involving...

Descamps, M.N. (author)
The gas-lift technique is a gravity-based pumping technique used for recovering oil from a production well. Gas injected at the bottom of the production pipe reduces the gravity component of the pressure drop and thereby, stimulates the supply of oil from the reservoir. This results in an enhanced oil production. Previous investigations have...

The aim of the thesis is to contribute to the understanding of the hydrodynamics of the gravity driven bubbly flow that can be found in bubble columns. Special attention is paid to the large scale structures that have a strong impact on several key parameters such as the degree of mixing, mass and heat transfer. An experimental investigation has...

The main goal of the project was the development of a plug flow reactor for the reduction of heavy metals (Cu2+) from industrial waste streams. Potential application of the reduction process inside The Netherlands lies in the IC and galvanic industry, where small waste streams containing aqueous copper exist. Outside The Netherlands, the process...
