Cold Box Assembly

Gases such as oxygen, nitrogen, and argon are used in many industrial applications. These gases are obtained through cryogenic gas separation technology, which involves condensing and converting air into a liquid form. The various elements can then be separated using fractional distillation. Air separation plants are distinguished by extremely low temperatures as low as – 200°C.

Air separation unit manufacturers in India like Brise Chemical produces the creme de la creme of cylinder filing ASU plant in India. It allows you to maximize your return on investment while meeting all of your process requirements. The stable operation and dependability of the cylinder filing ASU plant in India mean that once commissioned, all you have to do is let it run at peak performance. It helps in reducing energy consumption vastly on one hand while also lowering operational costs on the other, thus eliminating the risk of downtime.

Insulating Material Used in Cold Box

Perlite is typically used to insulate the bulk of the cold box process. Slag wool is used in areas where access is required because it is easier to remove than perlite. Slag wool is most commonly found in turbine, pump, and valve boxes.

• Cryogenic Adsorbers
• Heat exchangers
• The cold end of the turbine
• Separators
• Distillation Columns
• Piping and Valves
• Expansion Turbines
• Adsorbers
• Cryogenic Pumps

Issues That Can Arise Out of Poor Cold Box Assembly

• Water PoolingIf water pools on any horizontal surface due to the loss of integrity of seals at any of the openings then it will freeze and become a hazard and stop the free movement of pipes or excessive weight loads. Ice will also take more time to thaw leading to a temporary shutdown of its functioning.
• Air LeakingIf air somehow gets inside the box, then the oxygen present in that air could condense on the liquid nitrogen pipework, posing a hazard; additionally, moisture can form ice in the perlite or slag wool, reducing insulation and making removal difficult. This is why cold box purge is an important element of the cold box process. It fills the insulation space inside the cold box with nitrogen.

Different Pipes Used in the Cold Box Process Assembly

• Instrument Piping
• Vent, Purge, and Drain Piping
• Process Piping
• Relief Valve Piping
