Henry's law and gas phase disappearance

TL;DR

This paper explores the application of Henry's law to model hydrogen dissolution in a water-hydrogen porous media system, formulating it as nonlinear PDEs with complementarity constraints.

Contribution

It integrates Henry's law into a phase diagram framework and formulates the dissolution problem as a set of nonlinear PDEs with complementarity constraints.

Findings

Henry's law is effectively incorporated into the phase diagram.

The dissolution process is modeled using nonlinear PDEs with complementarity constraints.

Provides a mathematical framework for hydrogen dissolution in porous media.

Abstract

For a two-phase (liquid-gas) two-component (water-hydrogen) system in porous media we discuss the formulation of the possible dissolution of hydrogen in the liquid phase. We show how Henry's law fits in a phase diagram. Then the problem is formulated as a set of nonlinear partial differential equations with complementarity constraints.
