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...

Introduction: A confusingly large number of noble gas components has been found in meteorites, based on distinct compositions, origins, carrier phases, or release characteristics [1]. The discovery that the carriers of the primordial noble gases survive acid treatment [2] led to the identification of several circumstellar grain types [3]. The oxidisable carbonaceous carrier “phase Q”, however, ...

A number of various commercial technologies are available to remove contaminants from gasification gases, particularly those biomass. However, new cheaper needed meet the stringent requirements in gas cleaning, especially for biomass production. In this paper, we discuss suitability sorbents prepared by us based on oxides or carbonates metals (Al2O3, CaO, CuO, Fe2O3, MgO, MnO, Na2O and ZnO) rem...

Ammonia emissions are associated with many agricultural operations including animal and poultry operations, waste and wastewater treatment operations, and fertilizer and manure land applications. The fate of ammonia released to atmosphere is affected by interaction with other gases, aerosols, and fine particles. These interactions affect the gas-to-particle conversion. This process alters ammon...

In order to enhance the selectivity of metal oxide gas sensors, we use a flow modulation method to exploit transient sensor information. The method is based on modulating the flow of the carrier gas that brings the species to be measured into the sensor chamber. We present an active perception strategy by using a DQN which can optimize the flow modulation online. The advantage of DQN is not onl...

Low productivities of bioprocesses using gaseous carbon and energy sources are usually caused by the low solubility of those gases (e.g., H2 and CO). It has been suggested that increasing the partial pressure of those gases will result in higher dissolved concentrations and should, therefore, be helpful to overcome this obstacle. Investigations of the late 1980s with mixtures of hydrogen and ca...

Bronchiolitis fibrosa obliterans, described first by Lange in 1901, is an obliterative process of the bronchioles in which there is extensive damage to the bronchial wall involving all the constituent elements (the epithelium, elastic tissue, and muscle fibres), and the lumen is partially or totally occluded by bronchial exudate organized by fibroblasts and capillaries. The disease is extremely...
