Flue Gas Treatment

Microalgae have high photosynthetic efficiency that can fix CO2 from the flue gas directly without any upstream CO2 separation, and concomitantly produce biomass for biofuel applications. These gases, both untreated and treated into current discharge standards, contain CO2, N2, H2O, O2, NOx, SOx, CxHy, CO, particulate matter, halogen acids and heavy metals. Microalgae population studies were conducted in a batch mode experiments at Power plant site of Chamois, Missouri. The experiments were conducted in different period (June to December 2011) of time. This study evaluated the effect of several heavy metals that are present in flue gases on the algae, focusing on the growth and accumulation of lipids in the algae that can be converted to biodiesel. The genus Scenedesmus presented the greatest richness of species and number of counted individuals in the flue gas ponds compare than non flue gas treatment ponds. Among the diatomaceae the genus Navicula sp, Nitizchia sp and Synedra sp. presented the next subdominant richness in the ponds. The last results of counted green algae Ulothrix sp and Coelastrum sp were least number of cells reported in these ponds. The heavy metal-contaminated in flue gas and also enter into the microalgae biomass population. Comparative studies were carried out by flue gas and control system of open ponds. Control system of microalgae population was represented in less amount of heavy metals compare than flue gas ponds.DOI: http://dx.doi.org/10.3126/ijasbt.v2i2.10247 Int J Appl Sci Biotechnol, Vol. 2(2): 114-120

Abstract One of the main pollution types is air pollution, which has a significant impact on the surrounding environment and on living beings. Major source of air pollution is combustion processes. There are many flue gas treatment technologies around the world. In this paper a new, innovative flue gas treatment technology – fog unit – is introduced. The goal of the fog unit is to treat flue gases that are emitted from households. In the European Union, including Latvia, at the beginning of 2020, a directive will come into effect that will set limits for emissions and the effectiveness for incinerators in households. The main focus of this study was to determine the most optimal operating mode for the fog unit by changing different operating parameters: sprayed water temperature, sprayed water flowrate and types of nozzles (drop diameters). Results show that the most optimal operating mode in terms of flue gas treatment efficiency and recovered energy is at water temperature: 20 °C, sprayed water flowrate: 250 l/h and nozzle: MPL1.12 M. However, electrical consumption of water circulation pump leaves negative effect on this operating mode.

Particulate Matter Pollution

AbstractThe paper displays results of the questionnaire called “Particulate matter pollution in air”, which serves as a tool to determine level of public awareness of the health risks related to pollution from small capacity heating equipment in households. Barriers for installation of the innovative flue gas treatment technology called a fog unit in households and possible mechanisms to decrease or prevent these barriers were defined. The first part of the questionnaire included overall information about participants: age, gender, education level, place of residence, activities to protect the environment and motives behind performing these activities. The remaining questions were divided in four groups: “Environmental views”, “Knowledge on air pollution”, “Willingness to pay”, “Choice of flue gas treatment technologies”. The results of questionnaire correspond with raised problem situations. Over 80 % of respondents lack information on pollution and possible consequences deriving from it, and on potential solutions to prevent pollution. Residents of households are willing to pay for installation of flue gas treatment equipment (capital investments).
