  • Glycol dehydrator absorbent circulation pump type (98.236(c)(4)(i)(B))
  • Report whether stripper gas is used in glycol dehydrator (98.236(c)(4)(i)(C))
  • Report whether a flash tank separator is used in glycol dehydrator (98.236(c)(4)(i)(D))
  • Report type of absorbent used (98.236(c)(4)(i)(E))
