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, ...

Building upon the foundation of the prior investigations, a three-fold classification of tight gas reservoirs is proposed in this paper which is based primarily on dynamic relationship between gas charging history and reservoir tightening process, coupled with tectonic evolution, source-reservoir relationship, migration and charging pattern. The three categories of tight gas are: (1) “pre-exist...

A new route has been investigated for the production of the Rb(Kr) generator parent radionuclide at low energy cyclotrons. The excitation function of the Kr(d,n)Rb reaction was measured up to 14 MeV using natural Kr gas as target, the activation method and a stacked gas-cell irradiation technique. The saturation yield of Rb over the energy range Ed 5 14 → 6 MeV amounts to 2.86 GBq/μA. A compari...

CO2 emissions from combustion flue gases have turned into a major factor in global warming. Post-combustion carbon capture (PCC) from industrial utility flue gases by reactive absorption can substantially reduce the emissions of the greenhouse gas CO2. To test a new solvent (AIT600) for this purpose, a small pilot plant was used. This paper presents the results of studies ...

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.

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...
