Issued topics of Doctoral Study Program:
  1. Computational modeling of fluids flow distribution in process equipment

    The work will be focused on computational modelling and analysis of flow and distribution of process fluids in process equipment. The purpose is to perform analytical and complex multidimensional modelling and analysis of the fluid flow distribution problematics and flow behaviour of process fluids (incompressible and compressible) in selected design types of process equipment for identification and formulation of design principles to achieve a uniform fluid flow distribution in the equipment. Work will be continuing the current research and development results achieved in this area at the Institute of process engineering. Work will present also discussion and formulation of observations, conclusions, recommendations, and equations to accuracy improvement of current computational design techniques for fluid flow distribution analysis in process equipment. The work will include in selected cases also confrontation of calculated values with results of operating measurement or experimental verification of analysed equipment, especially particularly values of performance parameters and pressure drops.

  2. Efficient solutions for energy saving projects in industrial and municipal areas

    This thesis is focused on the needs of an industrial company or a municipal building to reduce energy consumption. Typically these include energy systems with an electric or heat output in the range of tens of kW or MW. The potential for reducing consumption of primary energy resources is significant in this area. From the perspective of energy systems operators, the selection and implementation of specific energy saving measures is a major issue. The availability of effective procedures is very limited. Among the most popular practical methods for savings are Energy Management System (EM) and Energy Performance Contracting (EPC). The main part of these methods is always an energy audit. Various technologies and processes are a part of an industrial company's energy systems, which require high professional specialization. Any attempt for the most efficient operation in this field can be labelled as R&D activities and are usually outside the scope of the above-mentioned methods. The outcome of this work should be a set of procedures and tools which will lead to an effective solution for energy saving projects. Two important trends can be found in the literature; energy performance evaluation through detailed analysis of operational data and a broader usage of mathematical modelling with an impact on control systems. These are the main areas which the work will deal with. The aims to be achieved: - introductory research: efficiency of heat sources; heat, electricity, water and compressed air consumption in industry; process integration; an analysis of selected operating parameters; heat transfer and heat loss, available methods for energy efficiency projects - acquisition and analysis of experimental data with a focus on energy production and consumption in industrial and municipal areas, - modelling and simulation of selected systems to optimize energy consumption, - proposal of efficient instruments and procedures for complex energy saving projects in industrial and municipal areas - the application of the proposed instruments and procedures for optimizing a chosen system (case study)

  3. Experimental research of flow and heat transfer for petro-chemistry and energy sources

    The work will be focused on the collection of highly reliable and accurate data from laboratory experiments at a large-scale combustion facility for burners up to 2 MW. The work will include error analysis, statistical data analysis and data processing, designed to support advanced combustion simulations. Attention will be directed also towards the design and construction of experimental equipment and measurement techniques, precise process control and monitoring of operating conditions in experimental combustion research. The flow in modern burners with low NOx emissions has a complex structure with a significant tangential velocity component and its experimental analysis is highly important for the validation of numerical models. It is an area of key importance for the design of gas and liquid burners, fired heaters and combustion chambers in a range of industries, mainly in petro-chemistry and power production.

  4. Heat recovery for waste-to-energy plants

    Heat recovery system in units for waste-to-energy plants (WtE plants) can be without any doubts considered as one of the most important parts of processes like these. Heat exchangers are very important part of energy recovery system of WtE plants and selection of suitable types of heat exchangers represents primary importance in design of these systems. It is necessary to perform the design of heat exchangers with maximum degree of compactness in relation to process parameters like temperature, composition of process fluids, proximity to fouling and potential operational problems. Proper design of individual key pieces of equipment and convenient technology selection is an integral part of a complex approach.

  6. Innovative design of process equipment from a safety and reliability perspective

    Thesis is focused on the design of process equipment, especially heat exchangers, pressure vessels, condensers, and others. In the conventionally performed calculations the design uncertainties will be analyzed in relation to the methods commonly used. Motivation for the advanced designs of these equipment are usually potential economical savings. To achieve these, it is necessary to propose approaches or methodology for designing these equipment on the basis of detailed knowledge of the structural response of the equipment with respect to legislation requirements. Particular attention will be paid to devices under specific operating conditions causing uneven structural responses, when their design is not covered by analytical approach within normative codes. For these cases it is possible to use design by analysis. The thesis will discuss the approach of the design based on stress categories method and design according to limit states. The results of the work are crucial to achieving competitive device designs in achieving safety that is key to these devices.

  7. Minimisation of Greenhouse Gas Footprints

    Development of the methodology for further minimisation of Greenhouse gas footprints (including the carbon footprints). This will build upon the knowledge developed energy efficiency and water efficiency in the previous four topics. The footprint components will be described and the inherent interactions among the components and the underlying system factors will be investigated. A hierarchy of measures will be formulated, similar to the well-known waste management hierarchy, to enable footprint minimisation at minimal costs and minimal influence on other footprints. Further, the system models will be evaluated and improved for revealing the significant interaction pathways within the process networks and the associated degrees of freedom linked to the costs and footprints via the pathways. The accumulated knowledge will be used then to formulate the relevant procedures and engineering tools for improving the footprint performance of new and existing system designs.

  13. Retrofit of Industrial Utility Systems

    Extending and developing advanced procedures and tools for optimal utility operational planning to maximise the utility system efficiency and maximum capacity/investment utilisation.

The research will further analyse and optimise the operational schedules for the required relevant time scales to minimise the operation cost and environmental impact gauged by the relevant footprints (greenhouse gas, water, nitrogen, etc.). Storage of energy carriers, water and intermediate materials will be researched for maximising the efficiency under uncertain variations of the supply of resources and the demand for utilities.

Existing computational methods will be further developed and adapted to concrete processes and equipment.

  17. Total Site and regional integration methodology for thermal energy

    Extending and developing an advanced methodology for Total Site and regional integration methodology for thermal energy. The methodology extension will involve research and development activities in two dimensions. The first one is concerned with the development of the full tools set for each of the sub-areas: conceptual basis, modelling, simulation, performance targeting, optimal design of new systems, operational optimisation, and optimal retrofit. The second dimension of the activities aims at scaling up the principles and the procedures used for Process Integration at the process and site level to be used at municipal and regional levels. The latter involves a strong spatial development component and reinforced financial management component compared to the process and site levels.

  19. Water and waste water minimisation and water and energy minimization. Development of the methodology for minimisation of Nitrogen footprints. Combination with the Greenhouse Gas Footprints.

    Extending the methodology into water and waste water minimisation and water and energy minimisation. So far, these methods have been mainly developed at the levels of single processes. There are apparent benefits from extending them to the site level and applying the same material and energy exchange architecture as for energy in Total Site Integration. The approach to develop should include development of unified performance indicators based on thermodynamics, as well as targeting design and retrofit procedures based on those, relating this development to the current energy-only Utility System model. The retrofit of existing water systems will be covered next, completing the tool set for this field of research and making it available further to industrial partners. Another important part of the research on this topic includes the link of the research to the other Centre topics. For instance, the thermal dimension of waste water can be linked to the “Industry Interaction Interfaces” in item 2.a, while many of the organic contaminants in waste water streams can contain valuable components for extraction and reuse as well as waste materials for applying waste-to-energy – especially fermentation or anaerobic digestion.
