Amine still at a refinery in Texas, USA.
A 78.2-ft × 126-in amine still had a hard weight budget on its foundation pad. Pyrogel® XTE and XTF replaced calcium silicate and Pyrocrete®, cutting 6,000 lb of installed weight with equivalent thermal and PFP performance — and completing 10 days ahead of schedule.
A foundation pad with a hard weight budget.
The pad would have needed civil upgrade work to carry the original cal-sil + Pyrocrete® system.
- Foundation-pad weight limit. No headroom to add traditional insulation + PFP weight.
- Required reduction of installed weight. 78.2-ft × 126-in still — a major vessel.
- Thermal performance and PFP could not be compromised. Substitution had to be functionally equivalent.
Pyrogel® XTE + XTF replaced cal-sil + Pyrocrete®.
Combined into a single lighter package: 30 mm XTE on the vessel, 60 mm XTF on the skirt and head.
- 30 mm XTE on the vessel. Equivalent thermal performance to the cal-sil spec.
- 60 mm XTF on the skirt and head. Equivalent PFP performance to the Pyrocrete® spec.
- Foundation-pad upgrade avoided. Civil works eliminated from the scope.
- 4 insulators, 8-hour shifts. Crew completed installation pre-TAR with a small team.
- 10 days ahead of schedule. Full insulation completed early.
Civil work avoided. Schedule beaten by 10 days.
The lighter Pyrogel® package eliminated the planned foundation-pad upgrade — and the speed of installation closed out the full insulation scope 10 days ahead of plan, with only four insulators working 8-hour shifts.
