Contaminants in the feed gas to be liquefied are often either overlooked or more frequently difficult to predict and quantify. This results in an incomplete basis for designing an LNG facility capable of operating effectively at full production under the complete range of actual feed gas compositions.​

If the design has not addressed potential contaminants in the feed gas, it can result in creating an off-specification LNG product, lead to freeze out with resultant shutdowns or damage to equipment with a subsequent loss of LNG production. This issue is quickly becoming a major concern to the LNG industry, especially in the LNG facilities that receive pipeline gas.​

The session addresses the analysis and impact, and shows effective solutions to enable operation over a range of feed gas contaminants including:​

  • Prediction and analysis of feed gas contaminants​
  • New technologies and solutions to prevent freezing out in cryogenic sections of the plant​
  • Case studies – shared experience from operational LNG facilities​
  • USGC LNG facilities​
  • Liquefaction of biogas​
