Investigation of natural gas hydrate potential of the south Caspian Sea Mustafayeva, Z.; Parlaktuna, Mahmut (2023-01-01) Some unique characteristics of the Caspian Sea, especially the South Caspian Sea, such as low geothermal gradient, rapid sedimentation, a great number of mud volcanoes, suitable temperature and pressure conditions make it ...
Kinetic Analysis of Methane Hydrate Formation with Butterfly Turbine Impellers Longinos, Sotirios Nik.; Longinou, Dionisia Dimitra; Myrzakhmetova, Nurbala; Akimbayeva, Nazgul; Zhursumbaeva, Mariamkul; Abdiyev, Kaldibek; Toktarbay, Zhexenbek; Parlaktuna, Mahmut (2022-07-01) Heat generation during gas hydrate formation is an important problem because it reduces the amount of water and gas that become gas hydrates. In this research work, we present a new design of an impeller to be used for hyd...
The impact of methionine, tryptophan and proline on methane (95%)-propane (5%) hydrate formation Longinos, Sotirios Nik; Longinou, Dimitra-Dionisia; Parlaktuna, Mahmut; Toktarbay, Zhexenbek (2021-10-01) This study examines the impact of three amino acids such as proline, methionine and tryptophan on methane (95%)-propane (5%) hydrate formation with the use of different impellers. The concentration of amino acids was 1 wt%...
Kinetic study of methane hydrate formation with the use of a surface baffle Longinos, Sotirios Nik; Longinou, Dimitra-Dionisia; Celebi, Erdem; Toktarbay, Zhexenbek; Parlaktuna, Mahmut (2021-09-01) The kinetics of methane gas hydrate formation was obtained by different dual and dual mixed impeller experiments with surface baffle at 42.5 bars pressure and 2 degrees C temperature. The outcomes indicated that induction ...
Seismic velocity characterisation and survey design to assess CO2 injection performance at Kizildere geothermal field Parlaktuna, Mahmut; Parlaktuna, Burak; Sınayuç, Çağlar; Senturk, Erdinc; Tonguc, Erinc; Demircioglu, Oncu; Poletto, Flavio; Bohm, Gualtiero; Bellezza, Cinzia; Farina, Biancamaria (2021-08-01) The noncondensable gases in most geothermal resources include CO2 and smaller amounts of other gases. Currently, the worldwide geothermal power is a small sector within the energy industry, and CO2 emissions related to the...
Examination of asparagine, aspartic acid and threonine in methane (95%)-propane (5%) gas hydrates as kinetic inhibitors Longinos, Sotirios Nik.; Parlaktuna, Mahmut (2021-08-01) The formation of gas hydrates blocks oil and gas transportation in pipelines, nevertheless sufficient comprehension of gas hydrate behavior is the key to its prolepsis. Thus this study reports the impact of three amino aci...
Türkiye'deki Jeotermal Bölge Isıtma Sistemlerinin Gelişimi Parlaktuna, Mahmut; Parlaktuna, Burak (2021-07-06) Turkey is one of the few countries that has almost all possible applications of geothermal energy. Geothermal district heating has a relatively short history (since 1987) compared to other direct utilization but plays impo...
Kinetic analysis of CO2 hydrate formation by the use of different impellers Longinos, Sotirios Nik; Parlaktuna, Mahmut (2021-04-01) This study investigates the effects of types of impellers with the use of full baffle in carbon dioxide gas hydrate formation. In single impeller experiments initial hydrate formation rate is higher with the use of rushton...
Examination of behavior of lysine on methane (95%)-propane (5%) hydrate formation by the use of different impellers Longinos, Sotirios Nik; Parlaktuna, Mahmut (2021-03-01) Hydrate formation characteristics and hydrodynamic behavior have been investigated for mixture of methane-propane hydrate formation with pure water and with the amino acid of lysine 1.5 wt% at 24.5 bars and 2 degrees C. Th...
Are the amino acids inhibitors or promoters on methane (95%)-propane (5%) hydrate formation? Longinos, Sotirios Nik.; Parlaktuna, Mahmut (2021-03-01) In the present study, the effect of four amino acids is studied for inhibition or promotion of hydrate formation in methane (95%)-propane (5%) mixture-water system. Thus this study reports the impact of leucine, serine, hi...
