the paper introducedeffects of modified pyrolysis tar on flue gas desulfurization. this experiment selected the pyrolysis tar as the raw material, researched the effects on desulfurization performance under different modification solution, concentration, solid liquid ratio of pyrolysis tar and modified solution, calcination temperature and calcination time by 16 group orthogonal experiments. th...

This paper addresses the development of pilot scale sustainable technology for microalgae capture of CO2 from power plant flue gas in alkaline solutions to produce biodiesel from algal oil. A combination of computer tools for process simulation, economic evaluation, and environmental impact allow sustainable process assessment. Laboratory scale experiments for growth and culture for algae in la...

introduction thermal infrared integrated dust index (tiidi) is one of indices that is presented in this direction. the index operates based on four brightness temperature difference including wavelengths 3.7, 8.6, 11 and 12 micrometer. according to the studies, btd (bt12-bt11) is used for cloud detection. btd (bt8.6-bt11) is the index for separation for dust from sandy surface and btd (bt3.7-bt...

Oxides of nitrogen (NOx) is responsible for troposphere ozone and urban smog through photochemical reactions. The rapid economic growth and unlimited consumption of fossil fuels have resulted in large emissions of NOx. Due to the adverse environmental effects, environmental regulatory agencies are compelled to enforce stringent NOx emission standards. Recently promulgated Clean Air Interstate R...

Samples of active coke, fresh and spent after cleaning flue gases from communal waste incinerators, were investigated. The outer layers of both coke particles were separately removed by comminution in a spouted bed. The samples of both active cokes were analysed by means of densities, mercury porosimetry, and adsorption technique. Remaining cores were examined to determine the degree of consump...

The aim of this work was to study the genetic diversity among flue-cured tobacco cultivars. RAPD and AFLP analyses were used to assess the genetic similarity among selected accessions of flue-cured tobacco. Seventy eight RAPD and 154 AFLP polymorphic bands were obtained and used to assess the genetic diversity among 28 tobacco accessions. The cultivar relationships were estimated through the cl...

NOx removal from an actual boiler flue gas was investigated using a commercial ozonizor for indirect NO oxidation and a scrubber using Na2SO3 . The flue gas was in the range of 470~1,480 Nm/h, the gas temperature of 327C, and NOx concentration of 40 ppm. Approximately 80% of NOx removal efficiency was achieved during 180 min of system operation by maintaining pH of 8 and oxidation reduction pot...

This paper presents a novel application of neural network modeling in the optimization of sensor locations for the measurement of flue gas flow in industrial ducts and stacks. The proposed neural network model has been validated with an experiment based upon a case-study power plant. The results have shown that the optimized sensor location can be easily determined with this model. The industry...

A laser-based in-situ spectrometer using near infrared diode laser at 767 and 770 nm to detect potassium atoms in high-temperature environments is described. The device was used to investigate the thermal dissociation of KCl and to monitor K behind the flue gas filter (300mm diameter, 1000°C) of a 250kW-coal combustor, without the necessity of error prone gas sampling. With a response time of 2...

In this paper, the solubility of CO2 in AMP solution have been measured at temperature range of ( 293, 303 ,313,323) K.The amine concentration ranges studied are (2.0, 2.8, and 3.4) M. A solubility apparatus was used to measure the solubility of CO2 in AMP solution on samples of flue gases from Thermal and Central Power Plants of Esfahan Steel Company. The modified Kent Eisenberg model was used...
