A theoretical model for coal swelling induced by gas adsorption in the full pressure range

Adsorption Science & Technology, 2020
The phenomenon of coal swelling caused by gas adsorption is well known. For Enhanced Coal Bed Methane Recovery and carbon storage, coal swelling induced by gases adsorption may cause significant reservoir permeability change.

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

, 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 ...

Simulation of dilatancy-controlled gas migration processes in saturated bentonite using a coupled multiphase flow and elastoplastic H2M model

Journal of Rock Mechanics and Geotechnical Engineering, 2023
Dilatancy-controlled gas flow in preferential pathways plays a key role in the safety analysis of radioactive waste repositories. This is particularly the case for bentonite, an often-preferred barrier material.

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

Energy 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 ...

A new method for solving the fission gas diffusion equations with time-varying diffusion coefficient and source term considering recrystallization of fuel grains

Nuclear Materials and Energy, 2019
The fission gas swelling of nuclear fuels depends on the fission gas behavior in fuel grains, which will be accelerated by grain recrystallization occurred in some fuels.

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

Journal 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 ...
