for the vapour. x. are the compositions of the liquid that would be in equilibrium with the outlet composition of the vapour. y. are the compositions of the where NV is the vapour flux of the component at some point through the interface and daj is the interface area through which the flux passes. The mass transfer rates for liquid and vapour, Niïj and NiLj, are dependent on the mass transfer coefficients for each phase. There exist several correlations for the heat and mass transfer coefficients and these are dependent on the compositions in the bulk phase, the temperatures in the bulk phase and interface, and on the packing or tray geometries.

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
