Abstract:

This study arises from the development of carbon capture and storage technology (CCS) as a means of disposing of the large quantities of CO2 emitted by industry. In particular the need is identified to measure the impact of impurities such as N2 and H2 on solubility of H2O in dense phase CO2 since the formation of an aqueous phase in CO2 bearing carbon steel pipelines presents a risk of corrosion or blockage. Chapter 1 describes this background, paying attention to the current state of affairs with regard to the development and deployment of CCS. An historical review is undertaken of the signi

Abstract:

Gas hydrates are a topic of intense investigation primarily due to the vast amount of methane trapped in the form of gas hydrate on Earth and to the possibility of reducing greenhouse gas emissions via the sequestration of carbon dioxide in the form of gas hydrate. In the present study, phase equilibrium relationships of pressure, temperature, and composition in the liquid, vapour, and hydrate phases for the pure propane-water and CO2-CH4 mixed hydrate-water systems have been investigated. In the first part of the study, the concentration of propane dissolved in water in the presence of propan

So this study was measuring the solubility of ethylene at different conditions, and correlating the solubility by thermodynamic model. The correlation parameters will be used to predict the solubility of ethylene of conditions when the experimental data are not available. In this study, the solubility of
