Remarks
1) Installation capacity of electric facility (1 unit) = Guaranteed performance under contract (KWh/Ton) X Distillation per hour(Ton/h) X 1.7(Power peak ratio)
2) Installation capacity of electric facility (N units) = Installation capacity of electric facility (1 unit) + (N-1) *Electric capacity of guaranteed performance under contract
Ex) In case of 5 units of SMVR100 :
Installation capacity of electric facility (1 unit) = 60*(100/24)*1.7=425(kW)
Installation capacity of electric facility (5 units) = 425+(5-1)*250=1,425(kW)
Average daily power consumption = 50(kWh/ton)*100(ton/day)=5,000(kWh/day)
