Introduction

Liquid nitrogen is an essential resource across various sectors for cooling, preservation, and inerting purposes. Thus, in the context of modern manufacturing systems industrial nitrogen generation is a significant part.

Gone are the days, when companies relied solely on outside vendors. They instead install on-site cryogenic plants. These systems also provide stability supply, lower cost and improved efficiency.

Due to increasing demand, industrial nitrogen production continues to flourish worldwide.

What is Industrial Liquid Nitrogen Production

Industrial liquid nitrogen production involves large-scale liquefaction of nitrogen accompanied with cryogenic air separation technology.

Nitrogen is extracted from atmospheric air by the system. Afterwards, it cools nitrogen to around −196°C, turning it into liquid.

Air contains about 78% nitrogen. This is how industrial systems are able to extract and purify nitrogen for liquefaction.

Why Industries Need Liquid Nitrogen

Liquid nitrogen is commonly used throughout a number of different industrial processes.

First, it delivers ultra-low temperature thermal management.

Plus, it also protects against oxidation in manufacturing.

Moreover, it also supports bioprocess.

It also aids in enhancing production efficiency of many sectors

So, the industrial production of liquid nitrogen guarantees a constant resource and operational stability.

Industrial Liquid Nitrogen Production Process

The main steps of the industrial production process of liquid nitrogen are

Step 1. Air Intake

The atmosphere air is drawn through intake filters in the system.

Large particles are removed to protect equipment.

Step 2. Air Compression

The air compressor increases pressure.

Higher pressure improves cryogenic efficiency.

Today, modern compressors can cut energy use.

Step 3. Air Purification

The purification system removes:

l Moisture

l Carbon dioxide

l Oil vapor

l Hydrocarbons

l Dust

Hence, there is no ice formation in cryogenic equipment.

Step 4. Heat Exchange

Plate-fin heat exchangers allow purified air to enter them.

Cool air by the reintroduction of cold return fuel.

It therefore recovers refrigeration energy from the system.

Consequently, power consumption decreases.

Step 5. Cryogenic Separation

Air enters the distillation column.

Inside the column:

l Nitrogen rises

l Oxygen settles

l Argon remains in the middle

Thus, gases are separated continuously.

Step 6. Nitrogen Liquefaction

Nitrogen is cooled to -196°C.

Then, it becomes liquid nitrogen.

Then it is stored in insulated tanks.

This bodes completed producing of modern gaseous nitrogen.

Key Equipment Found in Industrial LN2 Facilities

A proper system consists of several major items, more likely.

Air Compressor

Delivers compressed air for the completions process.

Therefore, it determines production capacity.

Air Purification Unit
