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 ...... use of biomass made of organic matter to generate energy While capturing and storing CO> from burning biomass resulting in negative emissions. BECCS is a negative emission technology as the technology removes more CO» emissions than it emits hence termed carbon neutral. Sources of biomass include ...

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 ...... 2.2. Capturing after combustion In post-combustion systems, CO2 is captured from the flue gases produced by combustion of fossil fuels and biomass in air, before they are released into the atmosphere. The fossil fuel fired power plants burn a fossil fuel, such as coal or natural gas, to generate ...Lola Tomić, Vesna Karović Maričić, Dušan Danilović, Branko Leković, Miroslav Crnogorac.

The use of biological markers in determination of origin and type of organic matter in the Tisza river sediments
Snežana Štrbac, Gordana Gajica, Aleksandra Šajnović, Nebojša Vasić, Ksenija Stojanović, Branimir Jovančićević (2013)The objective of the study was to determine the origin and type of organic matter (OM) of the Tisza recent sediments along the distance of 153 km through the territory of Serbia. For this purpose group organic-geochemical parameters and biomarker compositions were used. All samples contain approximately same amount of OM, which was deposited under uniform, slightly reducing conditions. Based on the distribution of n-alkanes, the origin and type of OM could not be precisely estimated. However, n-alkane patterns ...... maturity.1 On the other hand, elevated concentrations of odd long-chain homologues (C25–C33) show that terrestrial OM also contributed to the precursor biomass.5,6 It should be noticed that oil derivatives, such as gaso- line and diesel, have different n-alkane distributions, which range from n-C6 to n-C12 ...Snežana Štrbac, Gordana Gajica, Aleksandra Šajnović, Nebojša Vasić, Ksenija Stojanović, Branimir Jovančićević.
