5. Questions from Last Presentation Why are we using the fluidized bed MTG reactor? – Catalyst Regeneration – Economics – Data Why is our methanol reactor at this pressure? – Normal operation How do we startup our facility – Syngas – Methane We are using an inefficient distillation scheme – Varied stages/RR ratio to no avail

6. Design Basis  6000 Short tons syngas/day  518 °F (270 °C)  725 psi (5 Mpa)  Product  Gasoline – 15,974 barrels/day  LPG – 4,263 barrels/day

15. Economics Overview  Plant Revenue: $575 Million/year  Profit: $87.2 Million per year  Simple Payback: 4.16 years  Plant Upfront cost: $363 Million  IRR of 25%  Cost of utilities, maintenance, and catalyst: $22.7 Million/yr (reduced by 1/2)

16. Analysis of NPV% vs. a Range of Gasoline Prices.

17. Analysis of NPV% vs. a range of LPG%

18. Analysis of NPV% vs. a Range of Syngas %

19. Analysis of NPV% vs. Plant Cost %

20. Detailed MTG Reactor Pricing  Sizing from NREL standards  Original price from NREL  6/10 factor for reactors  CEPCI to update prices  Total reactor cost = 13.8 Million

21. Plant Layout Considerations: 1. Location:- 1. It must be far from public areas (schools, living communities, etc) 2. Must have access to any transportation (Railroads, roads, sea, etc) 2. Safety & design 1. Employees safety plays an important role in plant design. 2. Also taking into account, for any future expansion & Space for maintenance. 3. Cost: 1. Includes: capital and operating.
