Exergy destruction in ammonia scrubbers

Resources, Conservation and Recycling, 2018
Abstract A theoretical ammonia scrubbing process by sulfuric acid solution is assessed with the concept of exergy. The exergy destruction of chemical neutralization is mainly (75–94%) due to changes in the chemical exergy of streams and thermal effects from the reaction while mixing effects have a limited contribution (6–25%).

SPLITTING THE TOTAL EXERGY DESTRUCTION INTO THE ENDOGENOUS AND EXOGENOUS PARTS OF THE THERMAL PROCESSES IN A REAL INDUSTRIAL PLANT

Facta Universitatis. Series: Mechanical Engineering, 2016
The total exergy destruction occurring in a component is not only due to the component itself (endogenous exergy destruction) but is also caused by the inefficiencies of the remaining system components (exogenous exergy destruction).

Analysis of Exergy Destruction of an Evaporator or/and a Condenser

Strojarstvo : časopis za teoriju i praksu u strojarstvu, 2009
This paper presents the exergy destruction of an evaporator or a condenser or evaporator and condenser. The exergy destruction can be analytically calculated by using the same non-dimensional variables which have been used by its energy analysis. The one additional variable is the ratio of absolute input temperatures of both streams.

Exergy Destruction in Pipeline Flow of Surfactant-Stabilized Oil-in-Water Emulsions

Energies, 2014
Exergy destruction in adiabatic pipeline flow of surfactant-stabilized oil-in-water emulsions is investigated in five different diameter pipes. The dispersed-phase (oil droplets) concentration of the emulsions is varied from 0% to 55.14% vol.
