Further advantages of the disclosed methods will be described in more detail herein.

Claims (31)

1 . A method of operating an integrated coal-to-liquid (CTL) process and an Integrated Gasification Combined Cycle (IGCC) facility comprising:

a) integrating a CTL process and an IGCC facility by sharing an air separations unit, a coal preparation unit, and a coal handling unit to form an integrated CTL process and IGCC facility, wherein the CTL process and the IGCC facility each comprises a respective gasification unit for the production of syngas;

b) splitting ownership of the integrated CTL process and IGCC facility between two or more owners;

c) selling a call option for the syngas produced from the IGCC facility process to the IGCC facility;

d) selling syngas produced from the IGCC facility to the CTL process with callback rights;

e) selling excess products, byproducts, and excess electricity produced from the CTL process to the IGCC facility; and

f) recording the cost of the transaction and the amount of inventory.

2 . The method of claim 1 wherein c) further comprises a call-option price signal comprising replacement power.

3 . The method of claim 1 wherein c) further comprises a call-option price signal comprising the cost replacement fuel for the CTL process.

4 . The method of claim 1 wherein d) further comprises exercising callback rights during peak season.

5 . The method of claim 1 wherein d) further comprises exercising the callback rights during failure of the IGCC gasification unit.

6 . The method of claim 1 wherein e) further comprises distributing raw material to the CTL process and the IGCC facility from the shared units.

7 . The method of claim 7 further comprising changing the distribution of raw material to each section from the shared units based on a price signal.

8 . The method of claim 8 wherein the price signal further comprises the profitability of the integrated facility.

9 . The method of claim 1 wherein e) further comprises negotiating the distribution of raw materials between the CTL section and the IGCC section.

10 . The method of claim 1 wherein b) further comprises joint ownership of shared units of the integrated facility.

11 . The method of claim 1 wherein d) further comprises a price trigger consisting of the cost of an alternative for electricity production.

12 . The method of claim 11 wherein the alternative comprises the obtaining liquid natural gas.

13 . The method of claim 1 wherein e) further comprises negotiating the price of the excess products, byproducts, and excess electricity produced from the CTL process.

14 . The method of claim 1 wherein f) comprises electronically accessing the record at a future date.

15 . A method of operating an integrated coal-to-liquid (CTL) process and an Integrated Gasification Combined Cycle (IGCC) facility comprising:

a) integrating a CTL process and an IGCC facility by sharing an air separations unit, a coal preparation unit, and a coal handling unit to form an integrated CTL process and IGCC facility, wherein the CTL process and the IGCC facility each comprises a respective gasification unit for the production of syngas;

b) selling ownership of shared coal preparation and handling units to a third party owner;

c) dividing ownership of the integrated CTL process and IGCC facility;

d) negotiating delivery of raw materials to each section independently with third party ownership

e) evaluating need for electrical power, and liquid fuels, or end products; and

f) negotiating distribution of syngas to each section, from the processing units of both sections.

16 . The method of claim 15 wherein f) further comprises selling options for the distribution of syngas produced by the IGCC units to the CTL section.

17 . The method of claim 15 wherein f) further comprises selling a gaseous byproduct of the CTL section to the IGCC section.

18 . The method of claim 15 wherein d) comprises selling surplus electrical credits purchased by the CTL section to the IGCC section.

19 . The method of claim 15 wherein b) comprises the third party ownership paying for the construction of the shared units of the integrated CTL process and IGCC facility.
