Flue gas condensation systems are designed in two ways: as a singlestage recuperative shell and tube heat exchanger and twostage systems with the first stage of the cooling recuperator (dry economizer, DE) and the second stage in the form of scrubber condensing water vapor and cleaning the flue gas (wet economizer, WE). An example of the first type is the installation presented in Fig.

Carbon capture, utilization, and storage (CCUS) is expected to mitigate CO 2 emissions significantly since CO 2 is captured from the flue gas emitted by power and industrial processes and then either used in manufacturing processes or sequestrated into geographical formations. CO 2 capture is an energyintensive process, and its energy consumption is affected by flue gas properties such as ...

If an increase of VOC emissions is expected, a spot measurement should be conducted at the coal mill stack during AFR cogrinding to ...

The adsorption capacity of coal varies greatly depending on the composition of the gas being adsorbed and the composition of the coal. A series of isotherms showing the adsorption performance of different gases in a low volatile bituminous coal ( R o = %) from western Canada were plotted by Chickatamarla and Bustin (2003) ( Figure ).

Adequate venting must also be provided, such that when there is an upset condition causing the gases to vent, the gases are released in a safe area and in a safe manner. Vent stacks should be as high as possible and clear of any buildings,

total gas volumes must be known. Gas volumes are normally calculated from the O 2 value measured on a dry basis (extractive system). If the water vapour content of the stack gases is known, a dry value for O 2 can be calculated from the wet (insitu) value. Alternatively, the probe must be used in an extractive 'dry' measurement system to

Coal is baked in an oven for about 1236 hours at about 1,0001,100°C (1,8002,000°F). This drives off impurities such as coal gas, carbon monoxide, methane, tars, and oil. The resulting material—coal with few impurities and high carbon content—is coke. The method is called coking.

Coke Oven Gas. COG is a strong fuel but it is less useful compared to other injected fuels in the lower part of the blast furnace. COG contains H 2 = 60%, CH 4 = 24%, CO = 6%, CO 2 = 2%, and N 2 = 6%, but only carbon in CH 4 is oxidized in the raceway to CO releasing heat. CO 2 reacts with coke carbon to CO consuming energy, whereas H ...

First of all, in the 'Combustion chamber' the equilibrium between coal and synthetic air (79 vol.% N 2 and 21 vol.% O 2) was calculated to obtain an idea of the hotfluegas composition leaving the combustion chamber. Both the gas phase and the condensed phase from the 'Combustion chamber' were taken as input for the following calculations.

Abandoned mine methane provides a good source of medium to high quality methane. Mine gas from abandoned mines typically contains no oxygen, and its composition changes very slowly. The methane content can range from 6080%. Even after coal mines are shut down, coal mine gas continues to be released. The composition of abandoned mine methane ...

In this study, the composition of tars collected during a sixday underground coal gasification (UCG) test at the experimental mine 'Barbara' in Poland in 2013 was examined. During the test, tar samples were taken every day from the liquid product separator and analysed by the methods used for testing properties of typical coke oven (coal) tar. The obtained results were compared with each ...
