Expander Plant Flowsheet Description

• Flowsheet description
• A single stage expansion of a light hydrocarbon
  stream
• First, feed stream is cooled through a feed
  chiller (X-1) any liquid is removed with a
  vertical separator (F-2).
• The vapor is expanded (E-4) liquids separated
  using a second vertical separator (F-3).
