Sir,

I have Ethylene Plant Charged Gas Compressor System for Steady State Process Simulation in some preliminary engineering software. I need to develop CGC flowsheet in simulator and it will be steady state model only.

I have Feed Flow in MTPH, Feed Mole Fractions for all feed components ,etc. How can I convert these component mole fractions to mole flows for all component. I need to do this as my simulation software does not accept mole fractions for components and instead it accepts only component mole flows Kmol/hr etc.

MY present approach is first evaluate average molecular weight of entire feed by multiplying individual component mole fractions to its component molecular weight and then taking sumproduct to get average molecular weight.

I use this final average molecular weight and divide total flow of feed in MTPH by this molecular weight and then i get feed molar flow here.

I use this feed molar flow and I have comp mole fraction already and then what i do is

: Individual component mole fraction multiplied by Total Feed molar flows to get individual mole flows

is this correct?

Please help me and guide me in this.

Best Regards,

Chetan Chavan
