1. The consumption of water, electricity, steam and wind belongs to (power consumption). 2. The operating cost of the fractionation tower is mainly determined by the consumption of the reboiler (heating steam or other (heating medium)) and the cooling water (or other cooling medium) consumption of the condenser. 3. The difference between rectification and distillation is (reflux). 4. The greater the relative volatility, the easier (easier) the liquid mixture will separate. 5. The reflux ratio is an important factor affecting the fractionation operation (operating costs) and (investment costs).
