Introduction

Liquid nitrogen is essential in many industrial applications for cooling and freezing as well as preservation and inerting procedures. Thus, info concerning the price of a liquid nitrogen encryption supports companies with superior investment methods.

You need to invest upfront in equipment, installing it and engineering a liquid nitrogen plant. Nonetheless, it can reduce long-run nitrogen supply costs if produced on-site, while being replaced by fertilization after the agronomic N surplus reaches summer.

Among industries, food processing, healthcare, pharmaceuticals, electronics and chemical manufacturing today opt for their own liquid nitrogen production systems.

What Is a Liquid Nitrogen Plant?

Cryogenic technology is used in a liquid nitrogen plant for the production of liquid nitrogen from atmospheric air.

It includes a compressor system for purifying air; Next, it filters out nitrogen from oxygen using cryogenic distillation. In final process, they cool nitrogen down to approx -196°C and liquify it.

A complete plant includes:

l Air compressor

l Air purification system

l Heat exchanger

l Expansion turbine

l Cryogenic distillation column

l Liquid nitrogen storage tank

l Control system

l Liquid Nitrogen Plant

l Cryogenic Air Separation Plant

l Air Separation Unit

l Cryogenic Air Separation Equipment

Overview of Liquid Nitrogen Plant Cost

The price of a liquid nitrogen plant also depends on many technical factors.

Generally, the total investment includes:

l Equipment cost

l Engineering cost

l Installation cost

l Transportation cost

l Commissioning cost

l Operation preparation cost

Small systems require lower investment. But in case of large industrial plants, more sophisticated equipment is required and consequently the engineering costs are higher.

So, suppliers regularly offer adapted quotations based on buyer specs.

Cost of Liquid Nitrogen Plant — Key Factors

The base price is affected by a number of direct factors.

4.1 Production Capacity

Production capacity is the most expensive expenditure.

Tiny liquid nitrogen plants have reduced components.

However, large industrial plants need:

l Larger compressors

l Bigger cold boxes

l More powerful turbines

l Larger storage tanks

As a result, more capacity means more investment in equipment.

4.2 Nitrogen Purity Requirement

Purity requirements also affect cost.

Even standard industrial applications may require high-purity nitrogen.

But there are industries that need ultra-high purity nitrogen.

Higher purity requires:

l Advanced purification systems

l Better separation technology

l More precise control systems

Consequently, equipment costs increase.

4.3 Plant Technology

Different technologies influence investment.

Cryogenic technology provides:

l High purity

l Large capacity

l Continuous operation

However, it requires advanced equipment.

Cryogenic Air Separation Process

Nitrogen Liquefaction Process

4.4 Automation Level

Data train: up to October 2023 Automation impacts investment and operation

Basic systems, on the other hand, need more manual control.

Advanced systems include:

l PLC control

l Automatic monitoring

l Remote operation

l Safety protection

So automation incurrs upfront costs but has long term efficiencies.

4.5 Storage Requirements

Storage tanks influence total project cost.

Larger tanks require:

l More materials

l Better insulation

l Additional safety systems

This means that the storage capacity should correspond to the real demand.

Equipment That Influences Investment Cost

The overall cost of liquid nitrogen plant depends on the main equipment.

Air Compressor

The compressor provides compressed air.

Giant compressors raise the required investments but achieve more production volume.

Air Purification System

The purification system removes:

l Water

l Carbon dioxide

l Hydrocarbons

High-performance purification improves reliability.

Heat Exchanger

Heat exchangers with high efficiency lower energy usage.

In addition, this enhances the operating economics over the long run.

Expansion Turbine

The turbine provides refrigeration.

Advanced turbines increase efficiency.

Cryogenic Cold Box

The low temperature equipment is storing in a cold box.

The design of it is what directly impacts manufacturing cost.

Storage Tank

This tank holds liquid nitrogen that has been prepared.

Higher capacity increases project investment.

Operating Cost of a Liquid Nitrogen Plant

In addition to initial investment, a business is only as good in the long run by investing on ongoing operating costs.

The main operating expenses include:

Electricity Consumption

Electricity represents the single largest cost of operation.

Therefore, energy-efficient equipment is important.

Maintenance Cost

Regular maintenance ensures stable operation.

Moreover, preventive maintenance reduces downtime.

Labor Cost

Automatic systems lowers the need for manual operation

Spare Parts

Long-term operation requires replacement components.

Therefore, supplier support is important.

Small vs Large Liquid Nitrogen Plant Cost Comparison
