Four-component gas/oil displacements in one dimension: Part II: Analytical solutions for constant equilibrium ratios
In this paper we derive closed form solutions for composition paths (integral curves of eigenvectors) for three- and four-component systems with constant equilibrium K-values, and we report example solutions that describe gas injection processes. Extensions to systems with an arbitrary number of components are discussed.
