InsulPOX is a cryogenic liquid-applied secondary containment epoxy insulating polymer concrete (IPC) overlay with low thermal conductivity for LNG and other cryogenic liquids storage and shipping terminals.
Stemming from research conducted with Brookhaven National Laboratory, ChemCo Systems is proud to announce a recent installation of CCS InsulPOX at an LNG facility on Long Island in New York. InsulPOX has also been installed as an insulating liner in the concrete trenches and sumps of a newly constructed Texas LNG liquification terminal now in operation.
This lightweight 3/4-1" thick insulating polymer concrete (IPC) overlay system reduces heat transfer from sump, dike and trench walls and floors. This low modulus epoxy polymer lining reduces the evaporation rate of spilled LNG and the vapor plume spread and lowers the concentration of flammable methane gas in the surrounding atmosphere. As the surface secondary containment layer, it also provides protection to the concrete and structural steel from potential cryogenic brittle fracture by insulating it from the -260 °F liquid should a spill occur.
The flexibility and toughness of the low modulus insulating layer provides excellent mechanical and thermal shock resistance. A long mixed useful life of the polymer during application makes installation hassle-free. InsulPOX can be installed as a seamless overlay directly on floors or cast in place on walls. Optionally, InsulPOX can be supplied in finished precast panels of 3/4-1" thickness and 4' x 8' width and length and installed quickly on both walls and floors. InsulPOX is formulated with a non-flammable, chemical resistant, thermoset binder. We are excited to contribute to the safe growth of LNG and LPG storage and terminal operations.
Why InsulPOX?
• Slows evaporation of spilled LNG by reducing the heat transfer of underlying concrete. Lowers the airborne concentration of evaporated vapors to avert explosive levels.
• Protects concrete from cracking and flexing due to severe thermal cycling due to exposure to -260°F (-160°C) LNG liquid or other cryogenic liquids such as liquid oxygen or liquid nitrogen.
• Protects reinforcing steel from cryogenic embrittlement.
• Resistant to mechanical and thermal shocks.
• Provides seamless installation.
• Field repair uses non-sag version.
• High compressive and tensile strength tolerates foot and light vehicle traffic.
• Can be installed very quickly in larger areas if precast panels are selected.
