All Implemented Interfaces:

Serializable

public class HeatExchangerCostEstimate
extends UnitCostEstimateBaseClass

Cost estimation class for heat exchangers.

This class provides heat exchanger-specific cost estimation methods using chemical engineering cost correlations for shell-and-tube, plate, and air-cooled heat exchangers.

Correlations are based on:

• Turton et al. - Analysis, Synthesis and Design of Chemical Processes
• Peters & Timmerhaus - Plant Design and Economics
