    BOILER DRUM CBD pH PROBLEM

    Thanks rngrrix, But we don't have Glycol system. Also we had CPU (condensate polishing unit) as well as DM plant. Also any contamination is not seems to be there as conductivity is normal.

    Repost: BOILER DRUM CBD pH PROBLEM

    We have two HRSGs of 80 TPH @ 105 Kg/cm2 & 500 Deg.C, running at 75 TPH. We are facing some problem regarding maintaining of Steam drum pH, Although BFW pH is >8.8 by adding Morpholine. Steam drum pH is not increasing beyond 8.8 ( some times come downs to 8.6) even after dosing TSP in steam...

    TO CALCULATE GAS COMPRESSOR FLOW

    Thank you Sirs, But Is there any simple formula to calculate flow in both the conditions, as we know that by reducing suction Temperature Gas volumetric & density will change but Mass flow will remain same ?

    TO CALCULATE GAS COMPRESSOR FLOW

    We had Centrifugal Lean gas ( Natural Gas) compressors which are driven by Gas Turbines. Lean Gas molecular weight is nearly around 16.5 , suction pressure is 10.7 kg/cm2 (g) & discharge pr. 24.5 kg/cm2(g). Suction Temp. is around 23 Deg.C. , inlet flow is 170 TPH with Antisurge full close and...
