It assumes that the gas is ideal, we all know that an one mole of an ideal gas at specified pres. And temp. (Standard condition) Has a specified volume regardless of the composition, this way u can convert these quantities. The mmscfd stands for million standard cubic feed per day so the pressure and temperature are standard conditions (60 F and 1 ATM).

From MMSCFH just divide by 836.6. Result will be kmol/hr.
Just play with some conversion here:
Gas mass flow (kg/hr) = Normal volume flow (Nm3/hr) x Gas molecular weight (MW) / 22.414
1 Nm3/hr = 37.325 SCFH
