All the leading cities in the world are slowly becoming inhospitable for human life with global warming playing havoc with the living conditions. Biomineralization of carbon dioxide using carbonic anhydrase (CA) is one of the most economical methods for mitigating global warming. The burning of fossil fuels results in the emission of large quantities of flue gas. The temperature of flue gas is ...

A mobile sampling and measurement system for the analysis of gaseous and liquid samples in the field was developed. An inductively coupled plasma optical emission spectrometer (ICP-OES), which is built into a van, was used as detector. The analytical system was calibrated with liquid and/or gaseous standards. It was shown that identical mass flows of either gaseous or liquid standards resulted ...

An investigation focused on the transformation and distribution behaviors of trace elements and natural radionuclides around a coal gangue brick plant was conducted. Simultaneous sampling of coal gangue, brick, fly ash and flue gas were implemented. Soil, soybean and earthworm samples around the brick plant were also collected for comprehensive ecological assessment. During the firing process, ...

We present the first report on bioinspired silica - produced using a green method - supported carbonic anhydrase for carbon capture and demonstrate significantly improved carbon capture efficiency and stability relevant to flue gas temperatures.

The purpose of this paper and its prequel is to introduce and develop a theory of toric stacks which encompasses and extends several notions of toric stacks defined in the literature, as well as classical toric varieties. While the focus of the prequel is on how to work with toric stacks, the focus of this paper is how to show a stack is toric. For toric varieties, a classical result says that ...

BioDeNOx is an integrated physicochemical and biological process for the removal of nitrogen oxides (NOx) from flue gases. In this process, the flue gas is purged through a scrubber containing a solution of Fe(II)EDTA2-, which binds the NOx to form an Fe(II)EDTA.NO2- complex. Subsequently, this complex is reduced in the bioreactor to dinitrogen by microbial denitrification. Fe(II)EDTA2-, which ...

Since there is no flue-gas desulfurization facility (FGD) in Australian Power Plants, the temperatures of flue gases from the plants range from 393–433 K which is much higher than the absorption temperatures in a typical post combustion CO2 capture (PCC) process. The additional cooling systems and equipments are required to cool flue gases. This adds to the cost, and water and energy consumptio...

In recent years, low energy accelerators has been rapidly developed for medical and industrial applications. This paper presents the current applications of accelerators for radiotherapy, electron-beam irradiation processing, production of radioactive isotopes, electronbeam coal-fired flue gas treatment, container inspection for customs and radiography. There are about 600 sets of electron lina...

Online detection and prognosis are very important for the safe operation of flue gas turbines. Compared with univariate monitoring of the process, multivariate process monitoring is more effective and can capture abnormal situation in the early stage. This paper proposes a new multivariate fault prognosis framework for the flue gas turbine with a hidden fault process based on independent compon...

Municipal solid waste (MSW) flue gas residues require further treatment prior to disposal or reuse, and vitrification is one of the main solidification-stabilization processes. This paper investigates the high temperature behavior of MSW flue gas residues, performed in laboratory experiments up to 1400 degrees C, and coupled with thermogravimetric analyses, X-ray diffraction, chemical and elect...
