The feasibility of operating a Non-Dispersive Solvent Extraction (NDSX) process in a continuous mode is analysed for the first time in this work. A configuration is proposed for the treatment of industrial effluents and ...

Let $\Omega$ be a periodic waveguide in $\mathbb R^3$, we denote by $-\Delta_\Omega^D$ and $-\Delta_\Omega^N$ the Dirichlet and Neumann Laplacian operators in $\Omega$, respectively. In this work we study the absolutely ...

When flowing wells no longer have enough energy to lift the reservoir fluids to the surface, the artificial lift methods are used. Lifting systems Continuous Gas-Lift are used in onshore wells and subsea environments, ...
