A new concept for seawater desalination integrated into an amine-based CO2-capture process is presented. It is based on the use of forward osmosis to transfer water from seawater into the absorption solution via a membrane. Desalted water can subsequently be recovered as the condensate from the desorber outlet or through membrane distillation from the absorber. Suitable membranes have been identified and the most promising one was selected for laboratory evaluation using representative amine solutions. The process performance parameters, membrane water flux and reverse amine flux were determined. The process performance was best for amino-acid salt solutions. Further work will focus on demonstration of the technology using a post-combustion CO2 capture pilot plant operating on real flue gas.

Sorption Enhanced Water Gas Shift (SEWGS) is an intensified pre-combustion capture process, based on a potassium promoted Mg/Al-hydrotalcite sorbent. The technology has demonstrated low energy requirements and high capture performances in real industrial settings within the Iron and Steel sector. Reactor modelling is an essential tool to develop energy and cost-efficient SEWGS units. The TNO developed model captures the fundamentals of the gas-solid thermodynamic and kinetic interactions, to accurately predict the multi-column behaviour, allowing for unit sizing and quantification of the energy requirements. The updated interaction model consists of Langmuir interaction for CO2, a competitive interaction site for CO2 and H2O, an exchange site where either CO2 or H2O is adsorbed and a pore condensation for high-pressure H2O. The updated model is validated against single column and multi-column operation with simulated blast furnace gas.

For laying of underground utility systems in urban conditions by the method of horizontally directed soil piercing, small-sized units are designed. Such units should have measurement systems for determining the spatial position of the piercing head. In known systems, the surface layer of the soil is used as a data transmission line for transmitting measurement information. This method of transmitting information signals in urban conditions is not very acceptable. Ground-based objects reflect electromagnetic radiation of the head transmitter which leads to distortion of the directional diagram of the emitter and complicates the reliable reception of measurement information. It was proposed to use an autonomous measuring system with an operating frequency of 5 GHz based on Wi-Fi technologies and an unconventional method of transmitting measurement information using hollow steel bars in the piercing unit itself. This transmission line has periodic discontinuities because of the bar design. These discontinuities accumulate as the piercing head advances. For the basic vibration type Н 11 , more accurate analytical expressions were obtained for calculating the power transfer coefficient of the measurement signal in such non-uniform lines. It was shown that inhomogeneity of the transmission line in comparison with its surface resistance does not significantly affect the transmission coefficient. For example, damping in the line increased by 1.2 dB with the maximum length of inhomogeneity of 5 mm and the total length of jointed bars of 50 m. It has been theoretically proven that the range of soil piercing with reliable signal reception can be up to 50 meters. The proposed method for transmitting information signals makes it possible to reduce the transmitter power, ensure noise immunity of the measuring system, and reliable reception of the measuring information throughout the entire piercing path

The systems maintaining thermal regimes are a necessary component of thermally-loaded radio-electronic equipment, without which its operation is impossible. The uneven distribution of heat emitted by components such as semiconductor lasers, receivers of intense infrared radiation predetermines the preference of thermoelectric coolers for them. The joint application of a cooler and a heat-loaded element significantly tightens the requirements for the reliability indicators and the dynamic characteristics of the cooler. The cause is the influence exerted by the temperature gradients in the soldered joints between different materials of thermoelements and the electrode of the substrate. The main parameters of thermoelectric coolers are the number of thermoelements and the value of the working current. When targeting the design of thermoelectric systems for ensuring thermal regimes based on reliability indicators, the optimization of the problem for the following set has been proposed: the number of thermoelements, the working current, and the relative intensity of failures. At the fixed branches' geometry, decreasing the number of thermoelements leads to a decrease in the heat load, which can be compensated for by increasing the working current of the thermoelectric cooler. A ratio has been derived for the relative working current corresponding to the minimum size of the set. Using the set makes it possible to choose the required working current, for which there is an extremum, which optimizes the process of control over the cooler. The win in the refrigeration factor, compared to the mode of maximum cooling capacity, is 15 %. This demonstrates the advantage of a comprehensive indicator, which allows the development of systems enabling thermal modes for practical application, in particular, on-board systems for which energy consumption is critical. The originality of the results obtained is related to a comprehensive criterion for the basic performance indicators, which has a minimum

Particulate matter pollution is still a challenge in developing countries. In the past years, many researches have concluded that it causes many adverse health effects. Filtering the particulate matter involves implementing costly equipment. This fact makes the small scale industry owners in developing country go for less efficient smoke filtering devices or no devices at all. In this review paper, a new device, smoke settling chamber (SSC), which is a settling chamber integrated with an ESP is presented. It is a cost efficient device as it works from the waste energy of smoke which it extracts by using a power generating system. The detailed working of the device is discussed along with diagrams. This review paper also presents the mathematical parameter for the working of such a device. This study concludes that this device can be given for manufacturing and further analysis after that.

This paper presents new approaches to investigating economic growth and innovation activity as well as analyzing investment in R&D needs and efficiency in the context of contemporary challenges for European integration. Our research modeled the impact of R&D investment on GDP growth under broad conditions of globalization. In addition to capital and labor factors, we took into account factors that influence climate change, keeping in mind their relation to economic activity. Additionally, we paid particular attention to other factors driving sustainable economic growth, such as consumption of scarce resources as well as in- equality and poverty. Herein, we proposed new modeling conceptions for evaluating the impact of R&D investment on economic growth. The suggested method was adapted to analyze the case of development processes in the European Union. Our research confirmed the hypothesis that R&D expenditure has a positive impact on economic growth, and the impact is much higher in well-developed EU economies under conditions of sustainable economic development and globalization. The research was based on the case of the European Union economies. The panel least squares method was applied for the modeling and estimations.

Purpose. Determination of the minimum required sounding depth for calculation of the earthing resistance for substations with a voltage class of 35 kV. Methodology. For each ratio of electrical resistivity values of soil layers, earthing resistance was calculated with changing of the layers separation depth from 0.4 m to h max , where h max is the layers separation depth in a two-layer soil at which the earthing resistance value becomes the same as in a uniform soil. Results. In the experiments carried out, a family of curves was obtained that describes the effect of separation depth of soil layers for various combinations of soil electrical resistivities and geometric dimensions of the earthing arrangement. The accumulated statistical data for substations with a voltage class of 35 kV made it possible to determine the required sounding depth depending on the maximum size of the earthing arrangement and the probability of the relative resistivity falling into the corresponding range of values. An algorithm is proposed for determining the required investigation depth by Wenner method as part of the electromagnetic diagnostics of the earthing arrangement of existing substations with a voltage class of 35 kV. Originality. For the first time, a probabilistic relationship was established between the ratio of the electrical resistivity of soil layers, the size of the earthing arrangement, and the necessary depth investigation of the geological medium. As a result it has been proven that there are substations for which the required sounding depth does not exceed the maximum size of the earthing arrangement. Practical value. The use of the algorithm developed in this work allows increasing the accuracy of the earthing resistance calculation of electrical installations with voltages above 1 kV operating in a network with isolated neutral.

The epoxy composites reinforced with banana fiber mat were fabricated through hand lay-up method followed by compression moulding process. The effect of fiber mat orientation, with and without crack on fracture behaviours, fracture toughness (KIC) and critical energy release rate (GIC) of the laminated composites were investigated by CT and SENB testing procedure. It was found that the KIC and GIC values were found higher for composites having without pre-cracked. The cracked composites showed lower performance during experimentation. The fracture surface morphology was investigated by SEM image of the fractured composites. The dimension stability was checked according to ASTM standard. It was concluded that the sequence of laminates (0/90)°/(45/135)° showed higher KIC and GIC rather than other laminated composites.

The global energy market is going through the unprecedented change. Ability to identify what driving forces will be transforming the markets in coming decades and shape the future of energy is a key for policymakers and industry in developing better working strategies. At the same time, the volatile context, complexity, and interdependence of the driving forces make the future energy landscape so uncertain and ambiguous that forecasts and predictions do not work.
With this in mind, we have applied a scenario approach that in our view provides a viable alternative to predictions. Scenarios not only help in mapping the possible futures but also get better prepared to act accordingly. The paper provides four possible scenarios of the future of energy and discusses challenges and opportunities in each one of them, suggesting implications for business and policymakers. The pace of innovations in energy and digital technologies alongside with the severeness of the international stance on the climate change will eventually define whether conventional business models can dominate in the future and what will be different in energy systems of the developed and the emerging economies.
