Introduction

Liquid nitrogen is used as a cooling, freezing, and inerting agent in many industrial applications. It is thus a key component in the industrial gas production system, which depends on liquefaction plant equipment like liquid nitrogen plants.

Most modern cryogenic plants combine advanced equipment. Additionally, they provide consistent production, high levels of purity and uninterrupted working. With the increased demand, complete LN2 plant equipment packages are being ordered by industries.

Liquid Nitrogen Plant Equipment Overview

Liquid nitrogen plant equipment are all the mechanical, electrical, and cryogenic systems that form liquid nitrogen out of the ambient air.

These systems take air, compress it and clean it up, cool it down, separate the gases that make up our atmosphere into nitrogen gas, and turn that gas into a liquid. Afterward, they keep bottled liquid nitrogen in cryogenic tanks.

Thus, the group of equipment is a complete industrial gas production system.

Basic Function of Liquid Nitrogen Plant Equipment

The equipment serves a number of important purposes.

First, it supplies compressed air.

Also, it purifies the air.

It also supports cryogenic cooling.

Moreover, it is capable of separating nitrogen from oxygen.

Last of all, it liquefies nitrogen.

So, all the devices assist stable LN2 production.

List of Main Equipment for Liquefaction Plant

A full-fledged system consists of various elements.

4.1 Air Compressor

The high Pressure AirFed compressor and attached to it.

Hence it is the building block to the system.

4.2 Air Pre-Cooling System

In this way, the system lowers air temperature prior to purification.

Moreover, it improves energy efficiency.

4.3 Air Purification Unit

The purification unit removes:

l Moisture

l CO₂

l Oil vapor

l Hydrocarbons

Hence, cryogenic freezing issues are eliminated.

4.4 Molecular Sieve Adsorber

This equipment removes trace impurities.

Hence, it guarantees superior high-purity application.

4.5 Plate-Fin Heat Exchanger

It is a very efficient cooler as it transfer cold energy.

Additionally, it drastically decreases energy usage.

4.6 Expansion Turbine

Refrigeration is produced by the expansion of gas in the turbine.

Therefore, it enables cryogenic temperatures.

4.7 Cryogenic Distillation Column

This is the central separation unit.

Inside the column:

l Nitrogen rises

l Oxygen sinks

l Argon remains intermediate

Thus, gases are separated continuously.

4.8 Liquid Nitrogen Storage Tank

LN2 is stored safely in the storage tank.

Moreover, it reduces evaporation losses.

4.9 Control System (PLC)

The PLC system manages automation.

So operators guarantee stable and secure operation.

l Liquid Oxygen Plant

l PSA Nitrogen Generator

l Industrial Gas Plant

Working Together of Liquid Nitrogen Plant Equipments

All equipment operates in a continuous way.

First, compressors supply air.

Then, purification units clean it.

Next, heat exchangers cool it.

After that, turbines generate refrigeration.

Whereas, the gaseous products are separated by means of distillation column.

And most finally, liquid nitrogen pools into a storage tank.

Therefore, integration ensures continuous production.
