At site we are having 2 GE frame 9E machines of dual firing capability. Natural gas and Napatha.
During natural gas operation, to heat it, we are using Indirect bath heaters(IDBH). it consumes around 1000 SCM of gas per day to raise the temperature of the gas flow (32000 SCM/hr @ ~28 Bar) from 32 deg C to 42 deg C during summer. My guess is Dew point temperature (DPT) of natural gas will be below the 0 deg C. i have discussed the same with our operation team but no body is agreeing to stop it (IDBH). their point is condensate MAY form. unlike 9FA. i guess 9E do not have any pre-request for Natural gas temperature at its inlet.
Natural gas composition (% Mole Fraction) - CH4- 93.4%, C2H6- 1.86%, C3H8 - 1.60%, Isobutane- 0.32, n-butane- 0.45, Isopentane- 0.13, CO2- 1.38, N2- 0.13, Sulfur- NIL.
i have googled but nowhere i found any formula(s) or any method to calculate the DPT of Natural gas (of different compositions) at different temperature and pressure.
Looking forward for help from the members to save natural resources.
