Ethylene recovery unit on the US Gulf Coast.

The unit was struggling to sustain its operating target; heat gain was eroding ethylene recovery.

• Degraded cellular glass on the splitter tower. Two prior turnarounds had installed cellular glass; both had degraded.
• Heat gain at sections of the unit. Insulation gaps created hot spots and process instability.
• Struggling to sustain target temperature. Recovery yields were below design.

The blanket’s superior thermal performance let the unit reach its target operating temperature reliably for the first time.

• Selected for superior thermal performance. Cryogel® Z meaningfully lower k-value than cellular glass.
• Achieved target temperature. Unit ran reliably at the design point post-installation.
• 3-point gain in ethylene recovery. Translated directly into incremental revenue.
• Payback under 11 months. Premium over cellular glass recovered through yield improvement.
