Abstract

A method of making carbon black. A method of making carbon black is described including combusting feedstock with plasma in an apparatus having a series of unit operations with individual capacities. The individual capacities of the unit operations are substantially balanced by replacing at least part of the feedstock with a feedstock having a molecular weight heavier than methane. This results, among other things, in increased utilization of the individual capacities of the unit operations and increased overall throughput.

Claims (40)

1. A method of making carbon black, comprising:

cracking a first feedstock with plasma; and

increasing overall throughput of a given grade of the carbon black by replacing at least part of the first feedstock with a second feedstock and cracking the second feedstock with the plasma, wherein increasing the overall throughput further comprises cracking a mixture of the first feedstock, and the second feedstock with the plasma.

2. The method of claim 1 , wherein the second feedstock is heavier than the first feedstock.

3. The method of claim 1 , further comprising cracking the first feedstock and the second feedstock in an apparatus comprising at least one reactor unit, at least one heat exchanger unit, at least one filter unit, at least one hydrogen gas removal unit, at least one pelletizer unit and at least one dryer unit.

4. The method of claim 1 , wherein at least one of the first feedstock and the second feedstock is a gas.

5. The method of claim 4 , wherein each of the first feedstock and the second feedstock is a gas.

6. The method of claim 1 , wherein the second feedstock comprises one or more aromatic hydrocarbons.

7. The method of claim 6 , wherein the second feedstock comprises one or more polycyclic aromatic hydrocarbons.

8. The method of claim 1 , wherein the second feedstock comprises one or more of ethane, propane, butane, acetylene, ethylene, butane, carbon black oil, coal tar, crude coal tar, diesel oil, benzene and methyl naphthalene.

9. The method of claim 1 , wherein the second feedstock is heavier relative to methane.

10. The method of claim 1 , wherein the second feedstock has a greater carbon content than the first feedstock.

11. The method of claim 10 , wherein the second feedstock has a % carbon by weight greater than the first feedstock.

12. A method of making carbon black, comprising:

cracking a first feedstock with plasma; and

increasing overall throughput of a given grade of the carbon black by replacing, at least part of the first feedstock with a second feedstock and cracking the second feedstock with the plasma, further comprising replacing at least part of the first feedstock with the second feedstock during cracking of the first feedstock.

13. The method of claim 12 , wherein the second feedstock comprises one or more of ethane, propane, butane, acetylene, ethylene, butane, carbon black oil, coal tar, crude coal tar, diesel oil, benzene and methyl naphthalene.

14. The method of claim 12 , wherein the second feedstock comprises one or more aromatic hydrocarbons.

15. The method of claim 14 , wherein the second feedstock comprises one or more polycyclic aromatic hydrocarbons.

16. The method of claim 12 , wherein the second feedstock is heavier than the first feedstock.

17. The method of claim 12 , further comprising cracking the first feedstock and the second feedstock in an apparatus comprising at least one reactor unit, at least one heat exchanger unit, at least one filter unit, at least one hydrogen gas removal unit, at least one pelletizer unit and at least one dryer unit.

18. The method of claim 12 , wherein at least one of the first feedstock and the second feedstock is a gas.

19. The method of claim 18 , wherein each of the first feedstock and the second feedstock is a gas.

20. The method of claim 12 , wherein the second feedstock is heavier relative to methane.

21. The method of claim 12 , wherein the second feedstock has a greater carbon content than the first feedstock.

22. The method of claim 21 , wherein the second feedstock has a % carbon by weight greater than the first feedstock.

23. A method of making carbon black, comprising:

cracking a first feedstock with plasma; and

increasing overall throughput of a given grade of the carbon black by replacing at least part of the first feedstock with a second feedstock and cracking the second feedstock with the plasma, wherein at least one of the first feedstock and the second feedstock comprises a feedstock mixture.

24. The method of claim 23 , wherein each of the first feedstock and the second feedstock comprises a feedstock mixture.

25. The method of claim 23 , wherein the second feedstock comprises one or more of ethane, propane, butane, acetylene, ethylene, butane, carbon black oil, coal tar, crude coal tar, diesel oil, benzene and methyl naphthalene.

26. The method of claim 23 , wherein the second feedstock comprises one or more aromatic hydrocarbons.

27. The method of claim 26 , wherein the second feedstock comprises one or more polycyclic aromatic hydrocarbons.

28. The method of claim 23 , wherein the second feedstock is heavier than the first feedstock.

29. The method of claim 23 , further comprising cracking the first feedstock and/or the second feedstock in an apparatus comprising at least one reactor unit, at least one heat exchanger unit, at least one filter unit, at least one hydrogen gas removal unit, at least one pelletizer unit and at least one dryer unit.

30. The method of claim 23 , wherein at least one of the first feedstock and the second feedstock is a gas.

31. The method of claim 30 , wherein each of the first feedstock and the second feedstock is a gas.

32. The method of claim 23 , wherein the second feedstock is heavier relative to methane.

33. The method of claim. 23 , wherein the second feedstock has a greater carbon content than the first feedstock.

34. The method of claim 33 , wherein the second feedstock has a % carbon by weight greater than the first feedstock.
