WebCoal boiler flue gases contain many impurities which are highly detrimental to an amine-based liquid absorbent. Flue gas pretreatment is needed, which generally consists of two sections: one dedicated to NO2 and SO 2 removal, and one dedicated to flue gas water saturation and cooling to 30–40°C. WebWith no demand on the system, except leakage, bring the system up to its normal operating pressure (P1, in psig). Select a second pressure (P2, about half the value of P1) and measure the time (T, in minutes) it takes for the system to drop to P2. Leakage (cfm free air) = [ (V x ( P1 – P2) ÷ (T x 14.7)] x 1.25. imart international market
