“…The GFCII surface has a higher value, irrespectively of Reynolds number in comparison to the former surfaces. The CSS surface has a saturated liquid holdup range of 0.001 -0.002 g/cm 2 while the maximum value of 0.002 g/cm 2 is only 12 percent of the GFCII surface value of 0.017 g/cm 2 . With the epoxy resin anticorrosive coatings, the saturated liquid holdup reduces compared with the CSS surface.…”

“…With temperature 40˚C -80˚C the critical saturation time is less than 500 seconds which is suitable in the industrial application and the saturated liquid holdup is more than 0.0162 g/cm 2 which is 8 times more than that of the CSS surface. The liquid holdup of surface with a temperature 90˚C rises very slowly with the critical saturation time exceeding 3600 seconds and the saturated liquid holdup is only 0.0110 g/cm 2 . The surface liquid holdup at temperature 40˚C/50˚C/60˚C/70˚C conforms to Hill 1 distribution respectively, 80˚C conforms to DoseResp distribution and 90˚C conforms to Exponential distribution.…”

“…Wet electrostatic precipitators (WESPs) are well suited for collection of acid aerosols, ammonium salt aerosol and fine particulates [1] [2], as well as various contaminants such as mercury [3]- [5] and usually installed behind the wet flue gas desulfurization (WFGD) serving as terminal control equipment to purify the flue deeply. As a result, WESPs are drawing more and more attention from coal-fired power plants and dust emission factories.…”

“…Usually, the temperature of the flue through the wet limestone-gypsum FGD is cooled down to 50˚C -60˚C [6] [7] and the discharging flue gas temperature of the ammonia process of desulfurization is about 70˚C [8] [9]. At present, the WESPs are installed behind the wet flue gas desulfurization and the flue gas temperature in the WESPs is slightly lower than that of desulfurization tower outlet and even more lower to 46˚C [2].…”

The additional anticorrosive coating and hydrophilic layer of glass fiber cloth (GFC) deposited on the carbon steel sheet (CSS) was experimented and the surface wetting characteristic of the hydrophilic modified collection electrode was investigated under single strand feed water condition. The distilled water was selected as the working fluid. The influence of Reynolds number on the surface wetting characteristic parameters and those parameters at different temperatures were specifically studied. The results indicate that the GFC surface with loose glass fiber bundles reveals remarkable surface wetting characterizations. The saturated liquid holdup of this surface is 8 -10 times more than that of the CSS surface; the surface flowrate value is 6 -8 percent of that of the CSS surface; the film rate of this surface is 28 -32 times more than that of the CSS surface; the average film thickness is between a third and a half of the value of the CSS surface. Good agreement is achieved between the WESPs working temperature and the experimental temperature range with remarkable wetting characterizations that provides a theoretical basis for the industrial application. Not satisfactorily, the hydrophilic modification surface is not able to survive high temperature.

“…Additionally, acid aqueous solution or addition of strong oxidants such as potassium permanganate may be used [Goetheer and Da Silva, 2012]. Knitted wire mesh, vane demisters, Brownian demister unit, wet electrostatic precipitators, multicyclons, adsorbers and condensers are also used [IEAGHG, 2012, Mertens et al, 2014, Knudsen et al, 2013.…”

The use of amine absorption in carbon capture technologies is related with the formation toxic and potentially carcinogenic amine degradation products such as nitrosamines and nitramines. These substances can be created within both the solvent and the atmosphere when air components (mainly NOx) and amines react with each other. These substances may pose environmental and health risks depending on the level and duration of the exposure. In this paper, formation and occurrence of nitrosamines and nitramines in carbon capture plants were described. Emission reducing technologies have been also mentioned. Furthermore, an overview of experimental data of emission of nitrosamines and other major degradation products has been pointed out.
