No. of bitstreams: 1 JoseAugustoFurtadoDeOliveira_TESE.pdf: 11981801 bytes, checksum: be6108ea3598a35772ebda5b1f75b6f4 (MD5) Previous issue date: 2014-06-02 / Ag?ncia Nacional do Petr?leo, G?s Natural e Biocombust?veis - ANP / O processamento prim?rio do g?s natural em plataformas como a do Campo de Mexilh?o (PMXL-1) na Bacia de Santos, onde o Monoetileno glicol (MEG) tem sido utilizado como inibidor da forma??o de hidratos, apresenta problemas operacionais causados por incrusta??es de sal na unidade de recupera??o do MEG. Pesquisa bibliogr?fica e an?lise dos dados de solubilidade de sal em misturas de solventes, a saber: ?gua e MEG, revelam que estudos experimentais est?o dispon?veis para um n?mero relativamente restrito das esp?cies i?nicas presentes na ?gua produzida, tais como NaCl e KCl. O objetivo deste trabalho foi desenvolver um m?todo de c?lculo para a solubilidade de um sal em misturas de solventes, neste caso, para o NaCl ou KCl em misturas aquosas contendo MEG. O m?todo de c?lculo estendeu o modelo de Pitzer, com a abordagem de Lorimer, para sistemas aquosos contendo um sal e um outro solvente (MEG). A linguagem Python no ambiente de desenvolvimento integrado (IDE) Eclipse foi usada na cria??o de aplicativos computacionais. Os resultados indicam a viabilidade da modelagem proposta para uma s?rie de dados de solubilidade do sal (NaCl ou KCl) em misturas de ?gua e MEG. Al?m disso, o aplicativo desenvolvido em Python tem demonstrado ser adequado para estima??o de par?metros e de simula??o / Primary processing of natural gas platforms as Mexilh?o Field (PMXL-1 ) in the Santos Basin, where monoethylene glycol (MEG) has been used to inhibit the formation of hydrates, present operational problems caused by salt scale in the recovery unit of MEG. Bibliographic search and data analysis of salt solubility in mixed solvents, namely water and MEG, indicate that experimental reports are available to a relatively restricted number of ionic species present in the produced water, such as NaCl and KCl. The aim of this study was to develop a method for calculating of salt solubilities in mixed solvent mixtures, in explantion, NaCl or KCl in aqueous mixtures of MEG. The method of calculating extend the Pitzer model, with the approach Lorimer, for aqueous systems containing a salt and another solvent (MEG). Python language in the Integrated Development Environment (IDE) Eclipse was used in the creation of the computational applications. The results indicate the feasibility of the proposed calculation method for a systematic series of salt (NaCl or KCl) solubility data in aqueous mixtures of MEG at various temperatures. Moreover, the application of the developed tool in Python has proven to be suitable for parameter estimation and simulation purposes
