Lower BOR Means Lower Carbon Emissions—VacuEco VPU Supports Greener LNG Terminal Operations
Reducing Heat Ingress Is the Most Direct Route to Energy Savings
Before we begin, here is a quick introduction for readers unfamiliar with the term.
VPU (Vacuum Insulation Panel / Polyurethane Composite Module), or a metal-envelope vacuum insulation panel–polyurethane composite module [“VIP + PIR/PU Composite Insulation Panel”], is a new LNG tank insulation material developed by VacuEco, a Super Tech company.
The idea is straightforward: vacuum insulation removes nearly all gas from the material, greatly limiting heat transfer. The composite has a thermal conductivity of about 1.2mW/m·K (0.0012W/m·K), delivering roughly 25 times the insulation performance of conventional perlite.
Put simply, VPU gives an LNG tank a high-performance thermal jacket.
