Heat Exchanger Fouling Tracker

Tracks LMTD, U-value degradation, duty loss, and estimated cleaning benefit ($/day) for each exchanger. Generates cleaning priority rankings.

Module 10 · Overview

Heat Exchanger Fouling Tracker

Heat Exchanger Fouling Tracker turns the #1 energy loss in a refinery — crude preheat fouling — from a quarterly engineering exercise into a weekly operational decision. It tracks LMTD, U-value degradation, duty loss, and estimated cleaning benefit ($/day) for each exchanger. The output is actionable: a priority-ranked cleaning list with dollar values attached.

Why It Wins

Crude preheat fouling is the #1 energy loss in a CDU — worth $1M–$5M/year in most refineries. Process engineers currently track this in hand-built spreadsheets. A dedicated fouling monitor that speaks to operators ("clean E-101 this week, save $18K/day") is immediately actionable.

Use Cases

Heat Exchanger Fouling Tracker in Action

Scenario
Weekly cleaning priority review
Every Monday, the process engineer pulls up the priority list. E-101 is leaking $18K/day, E-104 is leaking $9K/day. Maintenance gets a work request. Operations is informed. The decision is data-driven, not intuition-driven.
Scenario
Crude diet impact on fouling
A new opportunity crude is being considered. The fouling tracker shows the same crude correlated with elevated fouling on E-203 in 2024. The information feeds back into the LP planning decision.
Scenario
Annual cleaning campaign planning
The annual cleaning budget is being prepared. The tool ranks all exchangers by 12-month cleaning benefit, lets the team optimize the campaign within budget, and forecasts the energy savings.
