SINOYQX Melamine Foam for LNG Thermal & Cold Insulation

As one of the fastest-growing clean energy sources in the world, LNG production and trade are showing a good development trend. However, in the construction of LNG projects and related low-temperature projects, due to the ultra-low temperature characteristics of liquefied natural gas (around -196°C), special thermal insulation and cold preservation treatment is required for its storage and transportation.

The importance of cold insulation of LNG storage tanks

Maintain a low-temperature environment: LNG needs to be stored at low temperatures to remain in a liquid state. If the temperature inside the tank is too high, LNG will vaporize quickly, causing the pressure in the tank to rise, which may even cause danger.

Prevent leakage and volatilization: LNG is a flammable and explosive substance, which may cause fire or explosion due to leakage or volatilization. Therefore, cold preservation measures can prevent LNG leakage and volatilization and reduce safety risks.

It can be seen that maintaining a low-temperature environment in the storage tank is the key to ensuring safe storage of LNG.

Extend the service life of the storage tank: Cold preservation measures can reduce corrosion and aging of the inner wall of the storage tank and extend the service life of the storage tank. This is of great significance to ensure the safe storage and long-term supply of LNG.

Currently, in the field of low-temperature pipeline cold insulation, commonly used cold insulation materials mainly include PUR/PIR, foamed glass, modified phenolic foam, etc. However, during use, the following defects have occurred:

The thermal insulation performance decays quickly and the maintenance cost is high.

The cold preservation effect is poor and the cooling loss is large, which may easily bring danger to the storage and transportation of natural gas or other compressed gases.

The thickness of the package is large, which brings a lot of inconvenience to the intensive pipeline layout design.

Due to poor cooling effect, condensation is likely to occur and pipes are prone to rust.

The cold insulation layer is prone to moisture condensation, resulting in a humid working environment for the insulation layer, which will affect the cooling efficiency.

Compared with traditional cold insulation materials, SINOYQX melamine foam is particularly suitable for cold storage and heat insulation in cold storages, cold storage/freezers, LNG liquefied storage tanks, and LNG liquefied transport trucks or ships.

In terms of low-temperature thermal applications, SINOYQX melamine foam is a flexible elastomer plastic material with a three-dimensional network structure. It still maintains a complete physical and chemical structure at minus 180 degrees Celsius, so it still has excellent thermal conductivity at low temperatures and inhibits the convection of the inside and outside environments. Conduction and radiation heat conduction, excellent fire resistance (B1, UL94 V0 and HL-1) and insulating properties (does not generate any static and antistatic), acid and alkali resistance, corrosion resistance, aging resistance, light weight and low temperature flexibility, etc. performance, and because melamine resin foam is an elastic but non-fiber material, does not contain any dust, halogenated-free and hydrocarbons-free, flame retardants and/or toxic heavy metals-free, especially suitable for places with particularly high eco-friendly requirements , cold storage (pharmaceutical processing plant, fruit and vegetable preservation processing plant, food processing plant, meat processing plant and cold drink factory) cold insulation (thermal and acoustic insulation), refrigerated/freezer cold insulation (thermal and acoustic insulation), LNG liquefied storage tank cold insulation (thermal and acoustic insulation), LNG liquefied transport vehicle or Ship cold and thermal insulation (thermal and acoustic insulation).

At the same time of thermal insulation (cold), melamine resin foam also has excellent sound absorption performance (0.95NRC), so that the operation of freezer refrigerator/freezer cabinet, LNG liquefaction storage tank, LNG liquefaction transport vehicle or ship protection is quieter., to achieve multiple functions of noise reduction, heat insulation and heat preservation.

In the process of LNG storage and transportation, the cold preservation effect is not only related to the transportation efficiency of the entire equipment, but also has a vital impact on the safe production of the device. High-quality cold insulation materials can not only reduce energy consumption and reduce cooling loss, but also provide guarantees for enterprises to produce safely and create better benefits. The emergence of melamine foam perfectly solves the current problems of cryogenic insulation in LNG storage and transportation, and is the material of choice in the field of thermal insulation and cold insulation in the future.
