CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO<br>A presença de emulsões durante a produção de óleo causa vários problemas e traz desafios tecnológicos a serem vencidos, já que afeta a produtividade dos poços, a elevação artificial, o tempo de vida dos equipamentos e o processo de separação do óleo produzido. Existe incerteza em relação à origem das emulsões geradas durante a produção de petróleo, podendo resultar do escoamento no meio poroso, do fluxo turbulento no fundo do poço, nas bombas, ou nas instalações de superfície.

Abstract:
Produced water, a byproduct of oil and gas production, includes almost 98% of all waste generated by oil and gas exploration and their production activities. This oil contaminated waste water has a great impact on our environment and is considered to be a high-cost liability. The Department of Energy’s Oil and Gas Environmental Program is concerned with the development of new and affordable technology to clean this produced water. Organically modified clays are proposed as a good option for removal of oil from produced water. Organoclay, incorporated into a treatment process shows promise

Abstract:
A injeção de água é o método mais comum para manter a pressão e melhorar a recuperação de óleo contido em um reservatório. A eficiência de recuperação de óleo no caso de óleos pesados é limitada pela alta razão de mobilidade entre o fluido deslocante e o fluido deslocado. Como a sede mundial por energia aumenta todo ano, enquanto o fluxo de petróleo dos campos petrolíferos conhecidos juntamente com a descoberta de novos reservatórios declina a uma velocidade considerável, torna-se indispensável utilizar métodos mais efetivos para extrair o petróleo dos reservatórios conhecidos.

The investigation of glycerol – major by-product of RME production process – utilization was accomplished. One of the new possible utilization methods was researched, when

Abstract:
A produção de petróleo é geralmente acompanhada pela produção de água, que pode estar presente sob forma livre e emulsionada. As emulsões podem ser encontradas em quase todas as fases de produção: nos reservatórios, nos poços produtores, nas facilidades de produção, nos dutos de transporte, no processamento e no armazenamento O sistema de Bombeio Centrifugo Submerso (BCS) é um dos métodos utilizados na indústria para a elevação de petróleo para campos localizados tanto em terra como em mar. Ainda que seja o método de elevação artificial mais apropriado para a produção de petróleo quando há ele

Abstract:
<p>The elastic properties of oil/water/surfactant interfaces play an important role in the phase behaviour of microemulsions and for the stability of macroemulsions. The aim of this thesis is to obtain an understanding of the relationship between the structure of the surfactant molecules, the structure of the interface, and macroscopic interfacial properties. To achieve this aim, we performed molecular simulations of oil/water/surfactant systems. We made a quantitative comparison of various model surfactants to determine how structural changes affect interfacial properties and film rupture.

Abstract:
At the request of Fresenius Kabi an emulsion preparation system was designed with a maximum production capacity of  15 L and minimum of 3 L emulsion. The system was required to consist of one oil-tank, one pre-emulsion tank, two storage tanks and one homogenizer. The storage tanks were positioned on a movable carriage on the left side of the homogenizer and the pre-emulsion tank and oil tank was placed on a separate frame on the right side of the homogenizer. All tanks were equipped with individual temperature control and a stand-alone parallel cleaning system was designed. The system also had

Abstract:
Fuktbevarare är de produkter som oftast skrivs och rekommenderas av dermatologer, och den vanligaste typen av fuktgivare är lotioner och krämer. Dessa produkter är emulsioner, vilka ofta innehåller medicinsk vit olja (MWO) på grund av deras skyddande egenskaper samt enastående hudkompabilitet. Traditionellt så har de MWO som används varit parafinska. Då naftenoljor ofta har visat sig ha bättre emulsions stabilitet, har detta examensarbete ämnat attjämföra emulsions stabiliteten för Nynas ABs nya MWO, N-MWO, med en parafinsk motsvarighet, P-MWO. Jämförelsen av de två oljorna genomfördes genom a

碩士<br>元智大學<br>化學工程學系<br>90<br>The factors concerning the unstability of emulsion are very complex. Two of the most important factors are emulsification process and storage environment . In this report the effects of emulsification process including mixing speed, operation temperature, emulsifier concentration and emulsify type etc, on the stability of emulsion was discussed. The storage environment was controlled under 40C in oven. The experiment results indicate that : (1) high mixing speed causes a reduction in particle size. (2) raising temperature reduces the extend of hydration
