In gas processing facilities, minimum metal temperature usually sets the materials of construction. If metal temperatures below -46°C are predicted, Low Temperature Carbon Steel presents an embrittlement risk and designers must switch to expensive stainless steel construction. Such decisions have a huge impact on project costs, order times and project viability. In this webinar, we will present a case in which the decision was worth more than $1,000,000,000 in CAPEX.

Detailed analysis during the pre-FEED stage predicted much more accurate metal temperatures than those predicted by idealised analysis. Insight into dynamic behaviour and specific locations of concern allowed designers to reduce stainless steel construction from 80% of the facility to just 30%.

Topics covered

In this webinar you will learn about:

  • Determining minimum metal temperatures with detailed analysis
  • Case study of a gas processing facility
    • Predicting dynamic behaviour
    • Identifying specific locations of concern
    • Mitigating risks through system design
    • Optimizing materials of construction for reduced CAPEX
  • Identifying systems that require more detailed analysis
