Class BottleneckAnalyzer

java.lang.Object

All Implemented Interfaces:
Serializable
public class BottleneckAnalyzer extends Object implements Serializable
Bottleneck identification and debottlenecking analysis for process facilities.

Identifies production-limiting constraints in process systems and evaluates debottlenecking options. This is a key tool for production optimization and field development planning.

Constraint Types Analyzed

  • Separator capacity - Gas velocity, liquid retention time
  • Compressor limits - Power, surge, stonewall
  • Pump capacity - Head, power, NPSH
  • Heat exchanger duty - Thermal capacity
  • Valve Cv - Control valve sizing

Example Usage


BottleneckAnalyzer analyzer = new BottleneckAnalyzer(facility);
List<BottleneckResult> bottlenecks = analyzer.identifyBottlenecks();

// Show most limiting constraint
BottleneckResult limiting = bottlenecks.get(0);
System.out.println("Bottleneck: " + limiting.getEquipmentName());
System.out.println("Utilization: " + limiting.getUtilization() + "%");
