2C,
Thanks for pointing out to another important functions of Co-Gen with HRSG. Additional steam ( over 3000bbl/d) can be add to Algar`s boiler increasing the total steam output by 10% if needed.
As I posted before there are other benefits of having the Co-Gen.
Not going to grate details I did try to answer a poster question about how much additional income can Co-Gen add to CLL cash flow.
Once more, I can assure you that the cost of burning 3650 GJ/d of NG ($22,000/d) will be about twice as much as a daily cost of total Electricity Bill if the Algar would be supply from the Grid ($10,000/d). There are other important function of the CO-Gen.
Generating the income is not one of them.
