Chemical Process TermsAbsorption - correct answer A process in which a gas mixture contacts a liquid solvent and a component (or several components) of the gas dissolves in the liquid. In an absorption column or absorption tower (or simply absorber), the solvent enters the top of a column, flows down, and emerges at the bottom, and the gas enters at the bottom, flows up (contacting the liquid), and leaves the top. Adiabatic - correct answer A term applied to a process in which no heat is tran...
