Orsat

3.12 Experimental Products Analysis The constituents in trematode worm hit man is analysed by manner of Orsat apparatus. It measures the volume or break piddle fractions of CO2, CO and O2 in alter flue pipe assail. 1. KOH stem (CO2). 2.Pyrogallol resolve (O2). 3.CuCl2 mixed bag (CO). The Orsat apparatus as shown in Fig. 3.1 contains three pipettes containing chemical solution to absorb CO2, O2 and CO respectively. By opening the stop valve and tin the take bottle which contains urine, 100 cm3 of flue gas coolness is collected over water in the graduated trite burette. The valve of the pipette 1 is opened and the direct bottle is raised, so that all the gas is passed into pipette 1. The CO2 content in the flue gas sample is absorbed in KOH solution. The leveling bottle is lowered and the volume of gas is calculated, say, it is 89 cm3. That representation 11% of the dry gas is CO2 by volume. In the same manner, volumetric percentage of O2 and CO in the flue gas is measured by opening successively the pipettes 2 and 3. The remaining unabsorbed gas is N2. Since the sample is collected over water, and water vapour in the flue gas would have condensed during tacit consent process. The SO2 gas pull up stakes react with water in the container. So the flue gas compend thus measured is on the dry basis. CO2 + CO + O2 + N2 = 100% by volume.

allow us assume that the dry flue gas (dfg) analysis of a gas sample is 12% CO2, 3% CO, 5% O2 and 80% N2 by volume. So 1 groyne of dry flue gas contain 0.12 groin of CO2, 0.3 mole of CO, 0.5 mole of O2 and 0.8 mole of N2. The molecular freight of d.f.g then beco! mes satisfactory to (0.12 x 44 + 0.3 x 28 + 0.05 x 32 + 0.8 x 28) or 30.12 kg/kg mol. Molecular weight of d.f.g will be Mdfg = 44 CO2 + 28 CO + 32O2 + 28 N2 Where CO2, CO, O2 and N2 are the volumetric percentages in dfg as measured. This is the hydrometric topic of dry flue gas.
