The Federal Institute for Materials Research and Testing and the company AirRobot GmbH & Co. KG cooperate to develop a flying remote-controlled measuring system. The system is capable of operating in a variety of scenarios of gas emission, e.g. exhaust gas from a chimney, flue gas in case of a fire, gas emission in case of an accident of chemical or hazardous goods or in case of a terrorist act...

Injection of CO, into depleted natural gas reservoirs offers the potential to sequester carbon while simultaneously enhancing CH, recovey. Enhanced CH, recovery can partially offset the costs of CO, injection. With the goal of analyzing the feasibility of carbon sequestration with enhanced gas recovery (CSEGR), we are investigating the physical processes associated with injecting CO, into natur...

Experiments were conducted using a custom double-stirred tank reactor to determine the rate constants of reactions between nitric oxide (NO) and both pentaaminecobalt(II) and hexaaminecobalt(II) at temperatures of 298.2 and 303.2 K and pH levels between 8.50 and 9.87 under atmospheric pressure. The NO concentration of simulated flue gas stream ranged from 400 to 1400 ppmv. Ammoniacal cobalt(II)...

Inverse gas chromatography (IGC) has become an accurate, reliable and fast method for the physicochemical characterization of polymers and their blends, fibers, modified silica and other surfaces, surfactants, as well as, commercial stationary phases and their mixtures and petroleum pitches, heavy residues of oil distillation. Possibilities of application of inverse gas chromatography in the ch...

This study proposes a strategy for optimal design of hollow fiber membrane networks for post combustion carbon capture from power plant multicomponent flue gas. A mathematical model describing multicomponent gas permeation through a separation membrane was customized into the flowsheet modeling package ASPEN PLUS. An N-stage membrane network superstructure was defined considering all possible f...

Emissions of sulfur trioxide (SO3) are a key component of plume opacity and acid deposition. Consequently, these emissions need to be low enough to not cause opacity violations and acid deposition. Generally, a small fraction of sulfur (S) in coal is converted to SO3 in coal-fired combustion devices such as electric utility boilers. The emissions of SO3 from such a boiler depend on coal S conte...

The quantity of poultry manure generated each year is large, and technologies that take advantage of the material should be explored. At the same time, increased emphasis on the reduction of mercury emissions from coal-fired electric power plants has resulted in environmental regulations that may, in the future, require application of activated carbons as mercury sorbents. The sorbents could be...

Introduction The major anthropogenic sources of mercury emission are coal combustion and municipal waste incineration. However, it is very difficult to remove the mercury compounds, particularly elemental mercury vapor, which is not effectively captured in typical air – pollution control devices. It has been reported that activated carbon, particularly activated carbon impregnated with sulfur, ...

In this paper the changes in the heat capacity of cooling towers has been investigated as a result of injecting combustion products of boilers. In the tower, the air is re-heated through mixing with hot flue gas after passing through the heat exchangers. As a result of this process, the draft of the cooling tower is increased. The additional produced draft depends on the ambient temperature and...
