Pinch analysis and heat integration — composite curves, ΔTmin selection, MER targeting, grand composite, HEN synthesis, retrofit. USE WHEN: a task involves reducing utility cost, evaluating heat recovery, sizing utility duties, or comparing process alternatives on energy efficiency. Anchors on neqsim.process.equipment.heatexchanger.heatintegration.PinchAnalysis.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# NeqSim Heat Integration Skill
Linnhoff-method pinch analysis to determine minimum hot/cold utility duties,
the pinch temperature, composite & grand-composite curves, and to evaluate
heat-exchanger network (HEN) opportunities.
## When to Use
- Determining MER (Minimum Energy Requirement) for a flowsheet
- Setting utility duties before equipment sizing
- Retrofit analysis — quantify potential savings vs. existing HEN
- Comparing process alternatives on energy footprint
- Sizing utility headers (steam, cooling water) consistently across a plant
Standard reference: **B. Linnhoff & E. Hindmarsh (1983), Chem. Eng. Sci.**;
operational guidance from **Smith — Chemical Process Design and Integration (2nd ed.)**.
## Core Concept
```
Hot streams (need cooling) ──┐
├── shifted by ΔTmin/2 → temperature intervals → cascade → MER
Cold streams (need heating) ──┘
```
The pinch divides the system in two:
- **Above pinch** — heat sink (only hot utility allowed)
- **Below pinch** — heat source (only cold utility allowed)
- **Across pinch** — every kW transferred costs 1 kW hot + 1 kW cold
Three golden rules — **never** violate any of them:

How to install
mdr add equinor/neqsim/neqsim-heat-integration@sha256:bd0ce657efa6c4beThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
