Course Content

  • NATURAL GAS & NATURAL GAS LIQUIDS PRODUCTION & VALORIZATION

      • Field treatment of natural gas, transportation by pipe and associated quality requirements.
      • Natural gas monetization routes and NGLs markets.
  • MAIN QUALITY REQUIREMENTS

      • Quality requirements for commercial natural gases and associated products (ethane, LPG, condensates) and associated pre-treatment: mercury removal, conversion or adsorption of mercaptans (RSH), etc.
  • TECHNOLOGY USED IN THE NGL EXTRACTION UNITS

      • Review and main characteristics of the equipment used in the NGL recovery units: plate fine heat exchangers (typical pressure drops), turbo-expander (typical efficiency, acceptable liquid ratio, enthalpy drop), demethanizer (used internals and their efficiency).
  • NGL RECOVERY WITH CONVENTIONAL PROCESS

      • Needed notions of process performances and associated thermodynamics.
      • Process review.
      • Case studies:
      • Simulation of expansion of a natural gas stream through a valve and a turbo-expander, impact of operating parameters on NGL recovery and products quality.
      • Simulation of NGL recovery process with columns, impact of reflux on NGL recovery.
  • ORTLOFF PROCESS

      • Process review.
      • Case study: simulation of Ortloff process, impact of reflux stream composition on NGL recovery.
  • CRYOMAX PROCESS

      • Process review.
      • Case study: simulation of Cryomax process, comparison with Ortloff process.
  • NGL FRACTIONATION & ASSOCIATED TREATMENTS

      • NGL fractionation process review.
      • Case study: simulation of NGL fractionation process with mercaptans, mercaptans mass balance.
      • NGL needed treatments (Merox or equivalent) and comparison with the adsorption process on the main gas stream.
