Effect of Sorption Induced Swelling on Gas Transport in Coal [PDF]

open access: yes, 2018
In this study, an investigation of carbon dioxide sorption induced coal swelling and its effects on gas transport in coal is shown. The model presented is based on an existing coupled thermal, hydraulic, chemical and mechanical (THCM) model. A series of numerical simulations dealing with high pressure carbon dioxide injection in coal sample is ...

Effects of fracturing fluid migration with clay damage after different shut-in period on shale gas production performance

open access: yesEnergy Reports, 2022
Shale gas wells may experience intentional shut in after fracturing operation partly because of the belief that soaking is beneficial. Although a number of numerical models have been built to analyze the fracturing fluid leak-off problems, neither of ...

Swelling and softening behavior of iron ore-spent mushroom substrate composite pellets during carbothermal reduction

open access: yesJournal of Materials Research and Technology, 2023
In the present day, we have reached close to an optimum condition of CO2 emission when using coal or coke for iron making process. Carbon neutrality is achieved during carbothermal reduction by employing biomass as a reducing agent in composite pellets ...

Swelling Pressure of Double-Expansive Material and Its Active Support Effect for Coal Seam Gas Drainage Borehole

open access: yesAdvances in Materials Science and Engineering, 2018
To improve coal seam gas drainage performance, we developed a double-expansive (DE) material to seal the borehole. The swelling process of this material includes an initial swelling stage and a secondary swelling stage.
