A comprehensive thermal assessment of dry cooled supercritical CO2 power cycles

, 2020
In arid areas, dry cooling technology is a preferable alternate of wet cooling mainly owing to the scarcity of abundant water supply. However, the supercritical CO2 power cycle still offers considerable thermal performance even at higher ambient ...

Effect of Supercritical CO2 on PVDF

Volume 6B: Pipeline and Riser Technology, 2014
The pre-salt fields have a high content of carbon dioxide (CO2) that can be in the supercritical state due to reservoir conditions of temperature and pressure. This high concentration of carbon dioxide has a direct impact on the strategies used in the exploration and exploitation of the reservoir, including the selection of materials and equipment used

Adsorption characteristics of supercritical CO2/CH4 on different types of coal and a machine learning approach

Chemical Engineering Journal, 2019
The injection of CO2 into deep coal beds can not only improve the recovery of CH4, but also contribute to the geological sequestration of CO2. The adsorption characteristics of coal determine the amount of the greenhouse gas that deep coal seams can ...

Effect of supercritical-CO2 interaction time on the alterations in coal pore structure

, 2020
The supercritical CO2 (S-CO2) interaction time is a vital parameter in CO2 geo-sequestration in coal seams, which is under-evaluated up to date. Through this study, we provide an experimental insight into this aspect by evaluating the effect of S-CO2 ...
