Calculate the HP required for refrigeration to chill $100$ MMSCFD of a gas at $1000$ psig of the composition listed below from $40F$ to $0F$ using propane as a refrigerant. The evaporator temperature is $-10F$ and the propane condenser operates to condense the propane to a liquid at $95F.$ Assume $PK=3000$
