Amine reflux vessels are pressure vessels designed to handle condensed liquids (water + amine) and residual acid gases (H₂S, CO₂) from the overhead of an amine stripper column. Their design follows strict standards due to corrosive conditions and operational demands.
| Parameter | Typical Range | Notes |
|---|---|---|
| Design Pressure | 50–150 psig (3.5–10 barg) | Must exceed stripper overhead pressure. |
| Design Temperature | 200–250°F (93–121°C) | Matches stripper condenser outlet. |
| Material | Carbon steel (SS for high corrosion) | Lined or coated if severe H₂S/CO₂. |
| Corrosion Allowance | 1/8" to 1/4" (3–6 mm) | Extra thickness for amine service. |
| Vent Size | 2–6 inches (DN50–DN150) | For non-condensable gas release. |
Note: Amine degradation products (e.g., heat-stable salts) can accelerate corrosion—material choice depends on amine type (MDEA, DEA, MEA).
| Nozzle | Purpose | Typical Size |
|---|---|---|
| Inlet | From condenser | 6–12 inches (DN150–DN300) |
| Liquid Outlet | Reflux to stripper | 3–6 inches (DN80–150) |
| Vent | Non-condensable purge | 2–4 inches (DN50–100) |
| Drain | Sludge removal | 2 inches (DN50) |
| Issue | Cause | Solution |
|---|---|---|
| Corrosion | Wet H₂S, heat-stable salts | Use corrosion-resistant materials, monitor amine quality. |
| Foaming | Contaminated amine | Install mist eliminator, add antifoam agents. |
| Level Control Failure | Faulty instrumentation | Redundant level switches (LT, LAL, LAH). |
| Plugging | Degradation products | Regular flushing, filtration. |
