Polyurethane Foam Insulated LCO₂ Storage Tank
Introduction
Polyurethane foam thermal insulation LCO₂ (liquid carbon dioxide) storage tank is an atmospheric/low-pressure low-temperature storage tank that uses rigid polyurethane foam to cast on site or spray foam for thermal insulation. It is mainly aimed at CO₂ recovery and storage application scenarios that are small and medium-sized, intermittent operation, or sensitive to initial investment. It is an important supplement and economical alternative to traditional vacuum powder insulated large storage tanks.
Economic benefits
1. Relatively low manufacturing cost: The manufacturing process of polyurethane foam insulated storage tanks is relatively simple, with low initial purchase and manufacturing costs.
2. Low operation and maintenance costs: Low daily maintenance requirements, saving maintenance costs, compact structure, easy operation.

Main components
1. Tank body
a. Inner tank: made of stainless steel, used for storing low-temperature LCO₂.
b. Outer tank: made of carbon steel, used as a protective shell and supporting insulation layer
2. Insulation system
Polyurethane foam insulation layer: filled in the interlayer of the inner/outer tank, and formed a continuous and seamless insulation layer by pouring foam on site to eliminate cold bridges.
3. Pipeline and accessories
a. Inlet and outlet system: low-temperature valves and pipelines.
b. Instrument system: level gauge, pressure gauge, thermometer, safety valve and bursting disc.
c. Pressure boosting/reducing system: an evaporator or pressure reducing valve used to maintain stable pressure inside the tank.
4. Basic and safety facilities
a. Load bearing and anti settlement foundation: usually concrete ring beam or column foundation.
b. Cofferdam and leakage detection: meet safety regulations.
