Abstract
A stripping system includes: a boiler which generates steam by heating water; a first heat exchanger (latent heat exchanger) which collects latent heat of the steam generated by the boiler, and thereby condenses the steam into condensed water; a second heat exchanger (sensible heat exchanger) which collects sensible heat of the condensed water, and thereby heats untreated water absorbing ammonia; and a stripping tower which receives the heated untreated water introduced therein, and vaporizes the ammonia from the heated untreated water.
Claims8
A stripping system comprising:
- a boiler configured to generate steam by heating water;
- a first heat exchanger configured to collect latent heat of the steam generated by the boiler, and thereby to condense the steam into condensed water;
- a second heat exchanger configured to collect sensible heat of the condensed water, and thereby to heat any of untreated water absorbing ammonia and untreated water absorbing an acid gas by use of the collected heat;
- and
- a stripping tower into which the heated untreated water is introduced, the stripping tower configured to vaporize any of the ammonia and the acid gas from the untreated water.
