LNG and Printed Circuit Heat Exchanger

With its compact, efficient, reliable, high heat transfer area density, high pressure resistance and low temperature resistance, PCHE meet the needs of main low temperature heat exchangers for offshore floating natural gas liquefaction. It has become the first choice for the main low-temperature heat exchanger for offshore floating natural gas liquefaction.

Their size is usually 20% of the size of shell & tube heat exchangers, but unlike other compact heat exchangers, they can be designed for pressures up to 9000 psi (620 bar). The maximum pressure can reach 60MPa, the minimum temperature is below -200 ℃, and the efficiency is up to 98%, which is convenient for modularization.

Compared with brazed plate heat exchangers, PCHE are more resistant to high temperature, high pressure, corrosion, and are not easy to leak. They are more suitable for offshore floating natural gas liquefaction. Shenshi Diffusion Bonded High Efficiency Compact Heat Exchanger is a more cost-effective solution for LNG.

PCHE can be widely used in floating liquefied natural gas system; and natural gas liquefaction condensers, regenerators, natural gas regasification evaporators, gas-gas heat exchange in offshore oil rigs Device, supercooler, etc.

PCHE advantages/characteristic:

High heat transfer area density, high compactness and high heat transfer efficiency;

Less leakage and high welding strength;

Extreme high pressure resistance (maximum pressure resistance up to 60MPa) and high and low temperature resistance (-196 ℃ to 900 ℃);

Under the same heat load, its volume and weight are only about 1/6 of the traditional shell & tube heat exchanger.
