In below fig, how is the presence of another inlet of steam and air in the middle of the reactor useful?
  • a) It results in proper distribution of particles
  • b) Resultant temperature leads to decomposition of methane
  • c) It has not much effect and can be excluded
  • d) For increasing the speed of solids exit
Based on the current technology, do you consider Winkler gas producer efficient and is still better to use?
  • a) Yes, it can still be used
  • b) Depending on the process we should decide its efficiency
  • c) No, because of its high consumption of oxygen
  • d) No, because it is big in size.
