Analysis of polychlorinated biphenyls in transformer oils by automated online coupling reversed phase liquid chromatography-gas chromatography using the through oven transfer adsorption desorption (TOTAD) Interface
(Taylor & Francis Ltd, 2012-03)
An automated method for the direct analysis of polychlorinated biphenyls (PCBs) in transformer oil is presented. The proposed method uses the TOTAD (through oven transfer adsorption desorption) interface for the on-line ...
Forward scattering approximation and bosonization in integer quantum Hall systems

Contribuição ao estudo do desempenho de biorreatores airlift de circulação interna: análise das condições operacionais e da geometria do equipamento
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2018-04-26)
The high oxygen transfer capacity associated with low energy consumption have made the airlift bioreactor an important equipment to be used in bioprocesses, with the performance of these devices being strongly dependent ...
Permethylated β-cyclodextrin in liquid poly(oxyethylene) as a stationary phase for capillary gas chromatography
(Elsevier Science, 2009-10)
This paper reports the study of poly(oxyethylene) as a solvent for heptakis(2,3,6-tri-O-methyl)-β-cyclodextrin (PM-β-CD) and the potential of these mixtures for constructing enantioselective gas chromatography columns. ...
Experimental and CFD validation of the characteristic of the liquid-gas separation process in GLCC from the study of dimensionless numbers
(Universidad de los AndesIngeniería QuímicaFacultad de IngenieríaDepartamento de Ingeniería Química y de Alimentos, 2018)
The GLCC (Gas-Liquid Cylindrical Cyclone) is an effective equipment used to separate gas and liquid mixtures. In this work, the performance of the turbulence models RST and k-e was evaluated in terms of the correspondence ...
Experimental validation and CFD simulation of a Gas-Liquid Cylindrical Cyclone (GLCC©)
(Universidad de los AndesIngeniería QuímicaFacultad de IngenieríaDepartamento de Ingeniería Química, 2017)
This article constitutes an experimental and CFD simulation study of the separation performances of a Gas-Liquid Cylindrical Cyclone (GLCC) separator. The Oil & Gas industry has shown great interest in the GLCC because of ...
Estudo numérico e experimental do escoamento bifásico líquido-gás em um distribuidor
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2019-12-17)
In the oil industry, two-phase separators are used in the phase separation process, however these separators (GLCC, VASPS, Pazflor, among others) have large dimensions, making their handling, installation and maintenance ...
A supporting formulation for introducing gas-liquid reactions
(Elsevier, 2014-07)
In spite of the widespread industrial application of non-catalytic or homogeneously catalyzed gas-liquid reactions (GLRs), many undergraduate chemical engineering curricula do not include this subject and heterogeneous ...
