heat transfer

Absorption, Distillation, Stripping, Drying, Extraction are mass transfer operations. These operations are widely used in various (petro-) chemical separation processes. During such an operation either one (or more) component(s) in the vapour phase is transferred to the liquid phase and/or from the liquid phase to the vapour phase. Some examples are: Absorption is used for removal of gaseous hydrogen sulfide and/or carbon dioxide and/or mercaptans from natural Gas, Synthesis Gas, etc. (any process gas stream, really) by dissolving them in a (reacting) liquid stream. Distillation is used in every oil refinery and also in many chemical manufacturing plants in the separation and purification of the desired products. Distillation is the most important separation technique, in general. Distillation columns are very visible in the skyline of any refiny and many chemical plants.
