Class EmissionsTracker

java.lang.Object
neqsim.process.sustainability.EmissionsTracker
All Implemented Interfaces:
Serializable
public class EmissionsTracker extends Object implements Serializable
Tracks CO2 equivalent emissions and energy consumption for a ProcessSystem.

This class provides comprehensive sustainability metrics for process systems:

  • CO2e Emissions: Per equipment and system-wide accounting
  • Energy Consumption: Power breakdown by equipment type
  • Flaring Emissions: Direct and cumulative CO2 from flaring
  • Regulatory Reporting: Export formats for EU ETS, EPA, etc.

Usage Example:

ProcessSystem process = new ProcessSystem();
// ... configure process ...
process.run();

EmissionsTracker tracker = new EmissionsTracker(process);
EmissionsReport report = tracker.calculateEmissions();

System.out.println("Total CO2e: " + report.getTotalCO2e("kg/hr") + " kg/hr");
System.out.println("Flaring: " + report.getFlaringCO2e("kg/hr") + " kg/hr");
System.out.println("Power consumption: " + report.getTotalPower("MW") + " MW");

// Export for regulatory compliance
report.exportToCSV("emissions_report.csv");
