Integration of CO2 mitigation with nutrient removal from different wastewater sources can be realized by microalgae growth. In spite of being an option with significant environmental benefits, this technology still suffers from achieving high performances since atmospheric concentration of CO2 limits microalgae growth; i.e. biomass accumulation. This is why the use of flue gas with CO2 concentrations of 20-25% (by volume) should be considered as an inorganic C source for the microalgae culture reactors. This study has focused on the measurement of CO2 uptake and nutrient removal by microalgae as well as biomass accumulation in the photo-bioreactors containing domestic wastewater inoculated by freshwater microalgae cultures. The real flue gas (11% CO2) collected from an iron-steel industry was used to supply CO2. The total CO2 uptake was 0.75 g/L with a rate of 0.15 g/L.day in the reactors operated with autoclaved wastewater as the growth medium. The use of raw wastewater yielded 0.13 g/L total CO2 uptake with a rate of 0.06 g/L.day. The results indicated that microalgae culture was capable of tolerating high levels of CO2 and removal of nutrients from wastewater.

Trend Analyses of Meteorological Variables and Lake Levels for Two Shallow Lakes in Central Turkey YAĞBASAN, ÖZLEM; Demir, Vandettin; Yazıcıgil, Hasan (2020-02-01) Trend analyses of meteorological variables play an important role in assessing the long-term changes in water levels for sustainable management of shallow lakes that are extremely vulnerable to climatic variations. Lake Mogan and Lake Eymir are shallow lakes offering aesthetic, recreational, and ecological resources. Trend analyses of monthly water levels and meteorological variables affecting lake levels were done by the Mann-Kendall (MK), Modified Mann-Kendall (MMK), Sen Trend (ST), and Linear trend (LT) ...
CO2 hydrogenation to methanol and dimethyl ether at atmospheric pressure using Cu-Ho-Ga/gamma-Al2O3 and Cu-Ho-Ga/ZSM-5: Experimental study and thermodynamic analysis Tuygun, Cansu; İpek Torun, Bahar (2021-01-01) CO2 valorization through chemical reactions attracts significant attention due to the mitigation of greenhouse gas effects. This article covers the catalytic hydrogenation of CO2 to methanol and dimethyl ether using Cu-Ho-Ga containing ZSM-5 and gamma-Al2O3 at atmospheric pressure and at temperatures of 210 degrees C and 260 degrees C using a CO2:H-2 feed ratio of 1:3 and 1:9. In addition, the thermodynamic limitations of methanol and DME formation from CO2 was investigated at a temperature range of 100-400...
Flue gas injection for EOR and sequestration: Case study Bender, Serdar; Akın, Serhat (2017-08-01) The combination of carbon dioxide enhanced oil recovery (CO2-EOR) and permanent CO2 storage in mature oil reservoirs has the potential to provide a critical near-term solution for reducing greenhouse gas (GHG) emissions. This solution involves the combined application of carbon capture and storage from power generation and other industrial facilities with CO2-EOR. In order to reduce CO2 capture costs flue gas, which consists mainly of N-2 and CO2, injection has been proposed. The main aim of this research i...
CO2 injection into saline carbonate aquifer formations II: Comparison of numerical simulations to experiments Izgec, Omer; Demiral, Birol; Bertin, Henri; Akın, Serhat (2008-05-01) Sequestration of carbon dioxide in geological formations is an alternative way of managing extra carbon. Although there are a number of mathematical modeling studies related to this subject, experimental studies are limited and most studies focus on injection into sandstone reservoirs as opposed to carbonate ones. This study describes a fully coupled geochemical compositional equation-of-state compositional simulator (STARS) for the simulation of CO2 storage in saline aquifers. STARS models physical phenome...
CO2 injection into saline carbonate aquifer formations I: laboratory investigation Izgec, Omer; Demiral, Birol; Bertin, Henri; Akın, Serhat (Springer Science and Business Media LLC, 2008-03-01) Although there are a number of mathematical modeling studies for carbon dioxide (CO2) injection into aquifer formations, experimental studies are limited and most studies focus on injection into sandstone reservoirs as opposed to carbonate ones. This study presents the results of computerized tomography (CT) monitored laboratory experiments to analyze permeability and porosity changes as well as to characterize relevant chemical reactions associated with injection and storage of CO2 in carbonate formations....
