Abstract:

Sorbent of CuO loaded on complex carrier of attapulgite and activated carbon was prepared by incipient impregnation method for flue gas desulfurization. The effects of CuO loading, reaction temperature and components in flue gas on the desulfurization performance were investigated in a fixed-bed quartz reactor. The experimental results indicate that the sorbents of 20 wt% CuO loading has a high desulfurization activity under conditions of reaction temperatures 200-250 oC and 21000 h-1, and O2 is necessary for the high desulfurization activity of the sorbents.

Abstract:

SO2 Emission of sintering flue gas accounts for more than 70% of total SO2 emission of steel industry. The purpose of this paper was to use steel slag for desulfurization of sintering flue gas. Based on traditional circulating fluidized beds (CFB) for flue gas desulfurization (FGD), a new dry digestion CFB-FGD process was developed. The new process eliminated the traditional digestion procedure, and the functions of the reactor include preliminary dust collection, digestion and desulfurization. An pilot CFB installation with maximum flow rate of 8000 Nm3/h for flue gas desulfurization was esta

In this paper, utilizing the purified flue gas desulfurization (FGD) gypsum as raw materials to prepare calcium sulfate whisker (CSW) by hydrothermal method, the effects of the dosage of crystal modifier, reaction temperature, pH, etc. on the crystal morphology of CSW were discussed. The results show that the purified FGD gypsum can replace high-quality natural gypsum for the preparation of the CSW with excellent quality. The dosage of crystal modifier (K2SO4) and reaction temperature have a significant effect on the morphology and aspect ratio of CSW, while pH and reaction time have a minor e

Abstract:

This paper reports an exploratory study on the use of a sulfite-rich industrial effluent to enable the integration of a sulfite–sulfide–sulfate cycle to the conventional carbon and nitrogen cycles in wastewater treatment to achieve sludge minimization through the non-sludge-producing Sulfate reduction, Autotrophic denitriﬁcation and Nitriﬁcation Integrated (SANI) process. A laboratory-scale sulfite reduction reactor was set up for treating sulfite-rich synthetic wastewater simulating the wastewater from industrial flue gas desulfurization (FGD) units. The results indicated that the sulfite red

Abstract To investigate the adsorption kinetics and thermodynamic adsorption mechanism and laws of dry flue gas desulfurization, we prepared a new adsorbent by loading Cr, Cu, and Zn on TiO2-loaded multiwalled carbon nanotubes. Desulfurization experiments were also carried out. In this study, three kinds of samples were used for simulation and diffusion processes in the dynamic adsorption of different SO2 volume fractions in flue gas and thermodynamic model analysis of different temperatures in flue gas. Results show that the diffusion coefficient of SO2 in three kinds of samples ranges from 1

Abstract:

Non-thermal plasma (NTP) technologies can be used to treat a variety of gaseous pollutants, and extensive research has been carried out worldwide because of its high purification efficiency, low dependence on temperature, and other advantages. NO and SO2 are the main gaseous pollutants in coal-fired flue gas. The plasma dynamics for desulfurization and denitrification is a hot topic in the field of NTP pollutant control technologies. In this paper, a one-dimensional fluid model for the simultaneous desulfurization and denitrification of flue gas by negative direct current (DC) corona discharge

Abstract:

Increased tightening of air regulations is leading more electric utilities to install flue gas desulfurization (FGD) systems. These systems produce brine containing high concentrations of nitrate, nitrite, and selenate which must be removed before discharge. The H2-based membrane biofilm reactor (MBfR) was shown to consistently remove nitrate, nitrite, and selenate at high efficiencies. The maximum selenate removal flux reached 362 mg Se m−2d−1 and was higher than that observed in earlier research, which shows continual improvement of the biofilm for selenate reduction. A low pH of 6.8 inhibit

Abstract:

In the limestone/gypsum wet flue gas desulfurization pilot-scale test rig, key parameters such as SO2 absorption rate, mass transfer were experimentally determined．The results show that desulphurizing capacity of gypsum and fly ash is relatively weaker, which is only equivalent to fresh limestone with a content of 0.27% and 1.5% respectively. pH-t curve of slurry with different levels of fly ash could be divided into a sharply increasing stage and a steadily increasing stage. The leaching content of Mn2+ is about 9 times of Fe3+ , Mn2+ can form intermediate complex with HSO3- in the solution,
