The separation of liquid mixture components is relevant to many applications-- ranging from water purification to biofuel production -- and is a growingconcern related to the UN Sustainable Development Goals (SDGs), such as ``Cleanwater and Sanitation'' and ``Affordable and clean energy''. One promisingtechnique is using graphene slit-pores as filters, or sponges, because theconfinement potentially affects the properties of the mixture components indifferent ways, favoring their separation. However, no systematic study hasshown how the size of a pore changes the thermodynamics of the surroundingmixture. Here, we focus on water-methanol mixtures and explore, using MolecularDynamics simulations, the effects of a graphene pore, with size ranging from6.5 to 13 \AA, for three compositions: pure water, 90\%-10\%, and 75\%-25\%water-methanol. We show that tuning the pore size can change the mixturepressure, density and composition in bulk due to the size-dependent methanolsequestration within the pore. Our results can help in optimizing the graphenepore size for filtering applications.
