transfer, and one semester of computational methods for chemical engineering. The purpose of this handbook is to introduce students to chemical engineering separations in a way that most closely aligns with what most entry-level chemical engineers will do in the workplace. Most newly
Absorption and Stripping In addition to the distillation, there are other unit operations used for separating substances Absorption is the unit operation in which one or more components of a gas stream are removed from the gas mixture by being absorbed onto a non-volatile liquid (called a “solvent”) In this case, the solvent is the ...

Absorption: removal of H2S from natural gas by absorption with monoethanolamine or diethanolamine solutions. Stripping: removal of oxygen from water (for use with electronic material processing) by contacting with a nitrogen gas.
Absorption is a chemical engineering operation in which a condensable vapor is transferred from the vapor phase to the liquid phase. In practice, packed columns are most commonly used in this type of process. The goal of this project was to design a packed column gas absorber experiment to be implemented as part of the Unit Operations
Absorption is a unit operation where concentrations of some components in the gas phase are reduced by absorbing them to the liquid phase. This is usually done to remove a noxious component from the gas phase or to recover a valuable component to the liquid phase.
