Class SafetyScreener

java.lang.Object
neqsim.process.fielddevelopment.screening.SafetyScreener
public class SafetyScreener extends Object
Safety screener for rapid assessment of safety-related design requirements.

Estimates key safety parameters for concept-level assessment:

  • Blowdown time estimation
  • Minimum design temperature (JT cooling)
  • Hydrocarbon inventory
  • PSV sizing requirements
  • H2S/toxic gas considerations
  • Fire case scenarios

These are screening-level estimates to identify concepts that may require detailed safety analysis or have inherent safety challenges.
