Available technological procedures for capturing CO2 in the industrial and power generation sectors
Climate change is a major environmental issue caused by anthropogenic emissions of greenhouse gases. Capturing CO2 and storing it in suitable geological formations is one of the main technological solutions that can provide mitigation of CO2 emission into the atmosphere. Capturing CO2 represents the first phase in process of carbon capture and storage, and includes the application of various technologies for the separation of CO2 produced in the energy and industrial sectors. There are four main systems for capturing ...... presented an overview of methods for CO2 capture and different technological procedures for separation of CO2 such as absorption, adsorption, cryogenic distillation, and membrane-based separation.

Analysis Of the Process Of Carbon Capture Utilization And Storage In Underground Reservoirs
John Nyame (2024)The importance of mitigating the effects of global climate change has necessitated an in-depth exploration of innovative strategies to reduce carbon dioxide (CO2) emissions. Among these strategies, Carbon Capture, Utilization, and Storage (CCUS) has emerged as a promising and transformative solution. This master thesis delves into the diverse realm of CCUS processes, aiming to unravel the positives challenges, and opportunities within this dynamic field. The analysis begins with a systematic examination of carbon capture technologies, encompassing post-combustion, pre-combustion, and oxy-fuel combustion ......

Production of electricity from coal-fired power plants and accompanying CO2 emissions: comparison of EU-27 and US
Even in the third decade of the 21st century, large power plants are still responsible for more than half of the electricity production in Europe and US. They predominantly use fossil fuels in their work, which results in the emission of pollutants into the air, soil and water. In addition to the production of electric energy, fossil fuels, including coal, are used for industrial purposes.

Transition pathways of household heating in Serbia: Analysis based on an agent-based model
To explore pathways of the energy transition of household heating, an agent-based simulation model was developed for the case of the Serbian household sector. The model is focused on individual entities (households) with the objective to explore the effects of policy instruments on energy transition in households with individual heating systems. Empirically collected survey data were used as input for households’ attitudes towards sustainable heating. Simulations showed that the proposed instruments would lead to higher heating efficiency and less ...energetska tranzicija, modeliranje bazirano na agentima, sistemi grejanja, sektor domaćinstva, obnovljivi izvori energije, emisija CO2Boban Pavlović, Dejan Ivezić, Marija Živković.

Fuzzy optimization in hydrodynamic analysis of groundwater control systems: Case study of the pumping station “Bezdan 1”, Serbia
Dragoljub Bajić, Dušan Polomčić (2014)A groundwater control system was designed to lower the water table and allow the pumping sta-tion “Bezdan 1” to be built. Based on a hydrodynamic analysis that suggested three alternative solutions, mul-ticriteria optimization was applied to select the best alternative. The fuzzy analytic hierarchy process methodwas used, based on triangular fuzzy numbers. An assessment of the various factors that influenced the selec-tion of the best alternative, as well as fuzzy optimization calculations, yielded the “weights” of the alternativesand the ...groundwater lowering, groundwater management scenario, fuzzy analytic hierarchy process,expert knowledge, triangular fuzzy numbers, linguistic variables... scores by conventional methods, so decision making frequently involves uncertainties.

Determining the Groundwater Balance and Radius of Influence Using Hydrodynamic Modeling: the Case Study of the Groundwater Source “Šumice” (Kikinda, Serbia)
A groundwater flow model was developed to simulate groundwater extraction from the public water supply source of the City of Kikinda. The hydrodynamic model includes the municipal groundwater source of Kikinda (Šumice and the Jezero Well), but also an extended area where there are groundwater sources that provide water supply to three factories: (MSK, TM and LŽT - Kikinda).

Karst wastewater as a high quality, renewable and within the circular economy water resource
Jovana Nikolić, Vesna Ristić Vakanjac (2021)High quality drinking water in it’s natural state is becoming less and less available to the human population. Based on the expected climate changes, it is considered that this resource will be less in the world but also in our region. Also, the accompanying polluting components that exceed the maximum allowable concentration are increasingly present in the waters. Even after the water treatment, it happens that some components are still in the drinking water, which adversely affects human health. ...Jovana Nikolić, Vesna Ristić Vakanjac.

A contribution to the understanding of the discharge dynamics and water balance of the karst spring Gornji Dušnik (Suva Planina)
A sufficiently long time-series of daily discharges is needed to assess the discharge dynamics and calculate the water balance equation parameters of a spring (river source). The paper assumes that a catchment is gauged if a time-series of observations of at least 30 years is available, which is a rare case in Serbia. One-year monitoring is often set up to verify the reserves of a water source or spring intended for capture. Monitoring ceases after the final report is ...Aleksandar Tanasković, Vesna Ristić Vakanjac, Dušan Polomčić, Jelena Ratković.

Application of Membrane Technology for Separation CO2 from Natural Gas
Natural gas consists of a mixture of hydrocarbons with the largest share of methane, and non-hydrocarbon impure components such as N2, CO2 and H2S. In order to fulfill the gas market requirements, it is necessary to separate these unwanted components from the natural gas stream. There are several available technologies for the separation of CO2 from natural gas, such as: polymeric membranes, cryogenic distillation, absorption and adsorption.
