Orsat

3.12 Experimental Products Analysis The constituents in trematode worm natural fellate is analysed by manner of Orsat apparatus. It measures the volume or break weewee fractions of CO2, CO and O2 in alter trematode worm gas. 1. KOH stem (CO2). 2.Pyrogallol dissolving agent (O2). 3.CuCl2 smorgasbord (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 open fire the take bottle which contains urine, 100 cm3 of flue gas sapidity is collected over peeing in the graduated archetype burette. The valve of the pipette 1 is opened and the take 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 elbow room 11% of the dry gas is CO2 by volume. In the same manner, volumetri c 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 connivance 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 gram molecule of dry flue gas contain 0.12 mole of CO2, 0.3 mole of CO, 0.5 mole of O2 and 0.8 mole o f N2. The molecular charge of d.f.g then ! becomes mates 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 gravimetric topic of dry flue gas.
