Desenvolvimento de um flash multifásico na presença de hidratos
(Universidade Tecnológica Federal do ParanáCuritibaBrasilMestrado em Engenharia Mecânica e de MateriaisUTFPR, 2017-09-13)
Gas hydrates are crystalline compounds formed by hydrogen-bonded water frameworks. Hydrates are stabilized by non-polar molecules of low molecular diameters (guest molecules), which are occluded in cavities (host lattice) ...
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 ...
Industrial Byproduct-Based Concrete Subjected to Carbonation. Electrochemical Behavior of Steel Reinforcement
(ESG, 2012)
Samples of ASTM A-706 structural steel embedded in different concretes obtained from mixtures of alkali-activated steel slag and fly ash were exposed to accelerated carbonation under controlled conditions (4% CO2, 65% RH ...
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 ...
Investigação teórica da cinética de formação de hidratos de metano e dióxido de carbono
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia MecânicaUTFPR, 2017-07-07)
Hydrates are crystal structures that can be formed from the interaction of water molecules and low molecular weight gases such as methane, ethane, propane and carbon dioxide. These structures are formed under favorable ...
Modelagem termodinâmica do equilíbrio de fases de hidratos de gás a altas pressões
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia MecânicaUTFPR, 2017-06-21)
Thermodynamic modeling of hydrates at high pressures (in this work are considered high pressures those ones that can liquefy the hydrate former gas) helps the oil and gas industry to understand the events in oilfield ...
Carbide lime and industrial hydrated lime characterization
(ELSEVIER SCIENCE SA, 2009)
This paper focuses on the characterization of carbide lime (CL) - a by-product of acetylene production, composed mainly of calcium hydroxide with minor parts of carbonate - and compares its features to those of ""dry"" ...
