Table 6 Capital cost, total operating cost, and revenue of the three scenarios proposed

From: Novel ethanol production using biomass preprocessing to increase ethanol yield and reduce overall costs

  Description Capital cost (MM $) Total operating cost*
(MM $/year)
Annual revenue (MM $/year)
Scenario 1 CPC feedstock, with overliming $ 1.38 $ 31.20 $ 70.02
Scenario 2 WTC feedstock, with acidic preprocessing using process water $ 2.68 $ 20.24 $ 79.85
Scenario 3 CPC feedstock, with acidic preprocessing using process water $ 2.68 $ 30.41 $81.53
  1. * Total operating cost including the feedstock cost
