Class GasCompressionTemplate

java.lang.Object
neqsim.process.design.template.GasCompressionTemplate
All Implemented Interfaces:
ProcessTemplate
public class GasCompressionTemplate extends Object implements ProcessTemplate
Template for creating multi-stage gas compression systems.

This template creates a standard gas compression train consisting of multiple stages with interstage cooling and liquid knockout. The number of stages is determined automatically based on the overall pressure ratio or can be specified manually.

Features

  • Automatic stage calculation based on optimal compression ratio per stage
  • Interstage coolers with configurable outlet temperature
  • Knockout drums for liquid removal between stages
  • Support for wet gas and condensate-rich applications

Usage Example

ProcessBasis basis = new ProcessBasis();
basis.setFeedFluid(gasFluid);
basis.setFeedPressure(5.0); // bara
basis.setParameter("dischargePressure", 100.0); // bara
basis.setParameter("interstageTemperature", 40.0); // °C

GasCompressionTemplate template = new GasCompressionTemplate();
ProcessSystem compression = template.create(basis);
compression.run();
