Abstract
A method of producing synthesis gas via gasification in a Fischer-Tropsch plant, the method including providing a number of gasifiers, the number of gasifiers provided being at least one more than the base number required to provide 100% plant capacity of synthesis gas when each gasifier is operated at 100% gasifier capacity. A method of continually producing synthesis gas via gasification of a carbonaceous feed in a Fischer-Tropsch plant by providing a number of gasifiers, the number of gasifiers provided being at least one more than the base number required to provide 100% plant capacity of synthesis gas when each gasifier is operated at 100% gasifier capacity; and adjusting the amount of synthesis gas produced by adjusting the number of online gasifiers, the flow rate of carbonaceous feed to each gasifier, or a combination thereof. A system for carrying out the method is also provided.

8. A method of maintaining full production of product in a Fischer-Tropsch process, the method comprising:
manifolding a plurality of Fischer-Tropsch reactors to a plurality of gasifiers in a Fischer-Tropsch process having a required synthesis gas production flow rate for full capacity, whereby the plurality of gasifiers minus one is capable of producing the required synthesis gas flow rate, and wherein the plurality of Fischer-Tropsch reactors minus one is capable of producing full capacity of product. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A Fischer-Tropsch system comprising:
a plurality of gasifiers manifolded together, wherein the plurality of gasifiers have a synthesis gas production capacity greater than the required synthesis gas for operation of the Fischer-Tropsch system at full capacity, whereby at least one of the plurality of gasifiers may be taken offline and the remaining gasifiers ramped up to maintain full plant production. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29)
