Question

Give two examples of gas absorption with chemical reaction​

Answer 1

Answer:

An example of chemical absorption is the purification of natural gas by passing the natural gas through an aqueous solution of an ethanolamine in which any acid gases, such as hydrogen sulfide (H2S) and carbon dioxide] (CO2), are removed from the natural gas by reacting with the ethanolamine (see the Amine gas treating and Natural gas processing articles). Another example is the removal of any hydrogen sulfide gas from the feedstock to an ammonia production plant by contacting the hydrogen sulfide with a bed of solid zinc oxide (ZnO) with which it reacts to form solid zinc sulfide (ZnS) (see the Ammonia production article).
