Resumo: | |||||||||||||
The study of hydrates rheology is becoming increasingly important due to the constant expansion of the oil and natural gas industry to deeper water. The hydrate formation process is a big concern mainly because, in many cases, it ends up generating the blockage of pipelines, safety problems, and loss of time and money. Hydrates are crystals compounds formed by water and small gas molecules at typical thermodynamic conditions of high pressure and low temperature. In order to study the hydrates phenomenon by analogy, chemical compounds that facilitate their formation at atmospheric pressure are used, such as cyclopentane (CP) and tetrahydrofuran (THF). In this study, an emulsion formed from CP, Primol oil, deionized water, and Span 80 (as stabilizer agent) is employed. Initially, the results aim to characterize the several parameters that influence hydrate formation, such as: shear rate, induction temperature, water volume fraction, cooling rate etc. In another set of results, the ability of reconstruction of the CP hydrates and the existence of a yield strength are assessed.
