Class SeparatorInternalsDatabase

java.lang.Object
neqsim.process.equipment.separator.entrainment.SeparatorInternalsDatabase
All Implemented Interfaces:
Serializable
public class SeparatorInternalsDatabase extends Object implements Serializable
Database of separator internals and inlet device performance data.

Loads performance specifications from CSV files in the resources/designdata directory. This provides a catalog of standard mist eliminator types, inlet devices, and coalescer plates with their grade efficiency parameters, K-factor limits, pressure drops, and mechanical properties.
