The gas flow rate is 80,000 M3 per hour, with 24 tons of steam added, and 20 M3 of quenching water added; the CO concentration at the inlet is 30% while it is 0% at the outlet. 35%
Total gas-to-vapor ratio: (20+24)*1000/18*22. 4/80000=0. 6845, that’s too high, isn’t it?
Reply to 2# TSCWSHQ: How was the formula above derived? Could you explain it in detail?
1. The saturation pressure of steam is higher than that of dry gas. 2. The volume of steam is greater than that of dry gas
In fact, it involves converting the total molar amount of effective steam or humidified hot water into a volume ratio relative to the volume of gas. Since the temperature of the water and the steam used can vary, it is difficult to determine the steam-to-gas ratio. The key factor is that the amount of water discharged varies, and the lost steam or hot water must be taken into account; otherwise, the figures obtained will be inaccurate
