Class ProcessBasis

java.lang.Object
neqsim.process.design.ProcessBasis
public class ProcessBasis extends Object
Class representing process basis (design basis) for a process template.

ProcessBasis encapsulates all the input data needed to configure a process template, including:

  • Feed stream conditions (composition, flow rate, P, T)
  • Product specifications (outlet pressures, temperatures)
  • Environmental conditions (ambient temperature, cooling medium)
  • Design constraints and safety factors
  • Company standards and TR documents

Example usage: 

ProcessBasis basis = ProcessBasis.builder().setFeedFluid(gasCondensate)
    .setFeedFlowRate(100000.0, "kg/hr").setFeedPressure(100.0, "bara")
    .setFeedTemperature(80.0, "C").addStagePressure(1, 70.0, "bara")
    .addStagePressure(2, 20.0, "bara").addStagePressure(3, 2.0, "bara")
    .setCompanyStandard("Equinor", "TR2000").setSafetyFactor(1.2).build();
