The Cryogenic Carbon CaptureTM (CCC) process is a retrofit, post-combustion technology that desublimates CO2 in the flue gas, separates the resulting solid from the remaining light gases, pressurizes the solid CO2, melts the CO2 and warms the light gas, and completes the CO2 pressurization with liquid CO2. This skid-scale CCC system has demonstrated successful carbon capture of 90–99% from simu...

Cost effective carbon sequestration schemes have been identified as a key need for dealing with carbon dioxide's (CO 2) impact on global climate change. Two main approaches are being pursued for sequestration: the enhancement of biological carbon sinks, and the capture and storage of CO 2. Since the bulk of the cost in a capture and storage sequestration scheme stems from CO 2 separation and co...

Here we show that combustion sources, including waste incinerators, metallurgical processes, power-heating systems and so on, are also important emitters of polybrominated diphenyl ethers (PBDEs) to the atmosphere. Geometric mean PBDE concentrations in the stack flue gases of the combustion sources ranged from 8.07 to 469 ng/Nm3. The sinter plants (24.7 mg/h), electric arc furnaces (EAFs) (11.3...

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...

An alyses of the components of municipal refuse were assembled, from which an average· composite analysis was calculated. The analyses of the flue and stack gases from 18 municipal incin erators were also tabu­ lated and plotted. A marked difference was n oted be­ tween the analyses of the stack gases and those to be expected from the combustion of the composite refuse. Much of the difference c...
