Dataset of wet desulphurization scrubbing in a column packed with Mellapak 250.X

Abstract

Flue-Gas Desulphurization (FGD) is a fundamental process commonly adopted for the treatment of exhausts deriving from both stationary and mobile sources. The removal of SO 2 from flue gasses can be made through different technologies and absorption offers the highest versatility for a large spectrum of applications. The data presented in this paper derive from FGD experiments carried out in a pilot wet scrubber equipped with a structured packing (Hastelloy C-22, Mellapak 250.X). The experiments aim to determine the SO 2 removal efficiency from a simulated flue-gas in different operating conditions, similar to those observed in common wet FGD processes. Experimental data are reported in terms of gas velocity, concentration of SO 2 in the flue-gas, liquid/gas feed ratio, fluids temperature and pressure. The dataset also includes the measurements of several working parameters, i.e. pressure drops in the column, wash water pH, relative humidity of the outlet gas and temperatures of gas and liquid flowing out of the FGD unit. The collection of these data could be useful in future studies and in the analysis of FGD units, also to design/improve large-scale absorption columns with structured packing, using various scrubbing liquids and in different operating conditions.

Study on the Effects of Wet Flue Gas Desulfurization on Particulate Matter Emission from Industrial Coal-Fired Power Plants

“…In China, the control of three primary air pollutants-NO x , PM, and SO 2 -is a priority for coal-fired boilers. To achieve this, selective catalytic reduction (SCR), electrostatic precipitator (ESP), and wet flue gas desulfurization (WFGD) technologies are widely installed in sequence [11][12][13][14]. Although ESP can remove up to 99% of fly ash, it is less effective for fine particles (smaller than 2.5 µm), and achieving the 5 mg/Nm 3 emission standard is challenging [15][16][17].…”

Courseware Fabrication of Flue Gas Desulfurization of Limestone-gypsum for Multimedia Teaching

“…Currently, emission reduction approaches commonly used are wet flue gas desulfurization technology such as limestone-gypsum method, ammonia method, seawater method, semi-dry flue gas desulfurization technology such as spray-drying method, circulating fluidized bed and dry flue gas desulfurization technology such as electron beam, pipeline injection, and spraying calcium inside the furnace and tail humidifying activation and spray drying. In recent some references there are some reports on these abovementioned and relevant technologies like simultaneous capture of carbon dioxide and sulfur dioxide [5][6], like different absorbents [7][8][9] and like different reactors [10][11].…”
