Class BottleneckAnalyzer

java.lang.Object

neqsim.process.fielddevelopment.evaluation.BottleneckAnalyzer

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() + "%");
