This state‐of‐the‐art, updated review provides an overview of technical issues in post‐combustion related process performance, energy requirements for capture, inconsistencies prediction cost. Recent updates are presented regarding chemical absorption‐desorption systems, particularly absorption solubility...

This study focuses on the integration of vacuum membrane distillation into multi-effect (VMD-MED) system, incorporating heat recovery mechanisms to augment fresh water productivity and minimize specific thermal energy consumption desalination process when compared stand-alone systems. The hybrid system was devised by integrating experimental output VMD (permeate flux hot brine) as source MED. Two systems were investigated in this study: VMD/MED, wherein heated brine from served a for MED,...

Post-combustion CO2 capture using monoethanolamine (MEA) is a mature technology; however, the high energy input requirements for solvent regeneration are still challenge MEA-based capture. In this paper, novel approach presented in which conventional absorption–desorption system integrated with capacitive deionization (CDI) such way to minimize heat duty requirement of stripper. The CO2-rich solution drawn from absorber column first sent CDI where ionic species adsorbed at oppositely charged...

Over the past few years, fuel prices have increased dramatically, and emissions regulations become stricter in maritime applications. In order to take these factors into consideration, improvements consumption a mandatory factor main task of research development departments this area. Internal combustion engines (ICEs) can exploit only about 15–40% chemical energy produce work effectively, while most is wasted through exhaust gases coolant. Although there significant amount thermal...

Capacitive deionization (CDI) is a technique used to desalinate saline water by means of electrical potential applied the electrode along both sides spacer channel through which flows. CDI operates either at constant voltage (CV) or current (CC) operation water. The purity main requirement outlet cell. lowest effluent concentration achieved within very short time operating cell CV, but after that continues increase. On other hand, in CC, later as compared with once it remain until target...

Abstract The combined removal of SO 2 and CO using aqueous ammonia has many advantages over the conventional processes, such as ability to capture multiple pollutants, low cost absorbent, high loading capacity, capacity regenerate solvent at temperature. In this paper, a closed‐loop absorption‐desorption process integrated with packed column flue gas desulfurization system was investigated. absorption modeled rigorous rate‐based RateFrac model in Aspen Plus, whereas stripper were based on...

Urea water solution (UWS) droplet evaporation characteristics directly affect the conversion and distribution of NH 3 in urea based selective catalytic reduction (SCR) system. The UWS temperature is very difficult to be measured directly. Whereas, this piece research work involves measurement by an Omega‐K type thermocouple 127 µm diameter. According changes droplet, process can divided into four steps. Droplets heat mass transfer processes are derived theoretically at high exhaust...

An aqueous ammonia based CO2 capture offers several advantages over the conventional monoethanolamine (MEA) solvent, including a high loading capacity, low stripper heat duty, lower degradation rate of equipment corrosion, and ability to multipollutants. However, in order make an aqueous, ammonia-based capturing process economically feasible, attention must be paid following issues: slip due evaporation ammonia, energy input for regeneration, removal efficiency improvements. In conventional,...

Nitrogen oxides emitted from power plants and the chemical industry are poisonous to humans animals, contribute ozone depletion, cause acid rain. More than 90% of nitrogen (NOx) consist nitric oxide (NO), which is insoluble in water. Among various available techniques NOx abatement, injection a promising method NO oxidized higher-order (NO3, N2O3, N2O4, N2O5), can easily be absorbed wet scrubber. In this article, process integrated with an absorber column numerically modeled simulated at...
