Brazed aluminium plate-fin heat exchangers (BAHXs) are capable of handling a wide variety of streams, provided they are clean and compatible with aluminium metallurgy, up to pressures greater than 100 bar (1450 psi) and temperatures of 204°C (400°F). They are robust, custom designed units manufactured to withstand combined thermal and pressure stresses. The following table summarizes typical applications.
|Plant types||Temp range, °C||Press range, bar (abs)|
|Industrial gas production||+65 to -200||1 to ≥100|
|Natural gas processing||+100 to -130||15 to ≥100|
|LNG||+65 to -200||5 to 100|
|Petrochem||+120 to -200||1 to ≥100|
|Refrigeration||+100 to -269||15 to 45|
