(Universidade Federal do Rio de JaneiroBrasilInstituto Alberto Luiz Coimbra de Pós-Graduação e Pesquisa de EngenhariaPrograma de Pós-Graduação em Engenharia MecânicaUFRJ, 2021)
Stability and cell distortion of sI clathrate hydrates of methane and carbon dioxide: A 2D lattice-gas model study
(Elsevier, 2015-09)
Thermodynamic models of the stability of clathrate hydrates are important for different applications such as the storage, separation and transport of gases. The development of improved models relies on a better understanding ...
Alkaloid-rich vs. antioxidant-rich yerba mate (Ilex paraguariensis) extracts: Exploiting the selectivity of supercritical CO2 using hydrated ethanol as co-solvent
(Elsevier Science, 2021-06)
Yerba mate (Ilex paraguariensis A.St-Hil.) is an autochthonous plant species from South America whose leaves exhibit beneficial health properties due to the presence of alkaloids and antioxidants. In the present study, the ...
Assessment of industrial gas hydrate inhibitors using the 3-in-1 technique
(UniandesIngeniería QuímicaFacultad de IngenieríaDepartamento de Ingeniería Química, 2017)
Suitability of a novel 3-in-1 technique to characterize industrial hydrate inhibitors was studied. Methane hydrates were formed using a concentration of 0.1 wt% of an unknown industrial inhibitor. Morphology, kinetics and ...
Modelo de predição para o crescimento de hidratos em paredes de tubulações
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2016-03-11)
The study of the clathrate-hydrate formation processes in pipelines is very important to the oil and gas industry because these structures can stop production and it represents a safety risk due to the pressure build-up ...
Experimental characterization of inhibited carbon dioxide hydrates above the upper quadruple point Caracterização experimental de hidratos de dióxio de carbono inibidos acima do ponto quádruplo superior
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2019-07-17)
Under specific conditions, water molecules can combine with gas molecules forming a solid crystalline structure called hydrates. The formation of this ice-like phase can block pipelines and is a major flow assurance concern ...
Laser Radiation CO2 Effects in Cement Paste at Different Hydration Stages after Preparation
