Dear All,
At Ammonia/Methanol steam reformer, for steam to carbon ratio moles of steam & moles of carbon are calculated based on flow & composition of feed e.g. Natural Gas.
Appreciate if anyone can explain why CO2 present in NG is not considered in total carbon number calculation?
Also i have seen as most of recycle gas(supplied for hydrogenation) contains some amount of CO which is used for measuring total Carbon of Steam-NG mix feed to reformer?
Regards
