Advantages of Nitrogen Plant

Efficient production

Liquid nitrogen plants are able to continuously and efficiently produce liquid nitrogen to meet the needs of industries and medical fields.

High purity

The liquid nitrogen produced is usually up to 99.99% pure, ensuring its effectiveness in a variety of applications.

Automated control

Modern liquid nitrogen plants are equipped with advanced automated control systems that can monitor and adjust the production process in real time to improve production efficiency and safety.

Energy-saving design

Many liquid nitrogen plants use energy-saving technologies to reduce energy consumption and reduce operating costs.

Safety

Liquid nitrogen plants are designed with a focus on safety and are equipped with multiple safety protection measures to ensure the safety of operators and equipment.

Flexibility

Liquid nitrogen plants can adjust production capacity according to customer needs to adapt to liquid nitrogen needs of different scales.

Main components of Nitrogen Plant

Air compressor

Rotary screw compressors for small plants with an output of 500m³/hr to 1000m³/hr; large plants use efficient centrifugal compressors.

Air pre-cooling system

All liquid nitrogen production units are equipped with efficient air pre-cooling systems to ensure optimal cooling of the gas.

Air purification system

Molecular sieve beds are used to remove carbon dioxide and moisture from the raw air at low pressure to ensure gas purity.

Distillation tower

A cold box unit using low-pressure technology, equipped with the most advanced plate-fin heat exchangers, condensers and sub-coolers, can provide nitrogen with a purity of up to 2-3ppm as a by-product without affecting the output of oxygen.

Expander

Turbo expander is used to cool and liquefy the gas in the process, and brakes through the booster, reducing energy consumption and stabilizing the working conditions of the upper tower to ensure long-term reliable operation.

Computer control

All equipment can be automatically configured through PC, equipped with electric cryogenic valves and external switching valves made in Germany or Japan, to achieve efficient monitoring and operation.

5 Safety Tips for Nitrogen Generator Installation

Check for Leaks
One of the biggest concerns involving the use of onsite nitrogen generators is the potential for too much oxygen depletion or enrichment in the jobsite location. A stable ratio of oxygen and nitrogen in the atmosphere is required. Leaks in the system can occur and alter that ratio by introducing too much nitrogen into the atmosphere if the pipework or nitrogen buffer tank vessel is damaged or leaking.

To prevent this from happening, it's important to ensure that the pressure vessels and pipes are properly installed and have an airtight connection during the nitrogen generator installation process. It is imperative to leak test the nitrogen generating system prior to putting it into operation.

Provide Proper Ventilation
Nitrogen generators consist of filtration materials that are used to separate oxygen and nitrogen from ambient air. Enhanced concentrations of oxygen are in the nitrogen generator waste gas stream.

For that reason PSA and membrane nitrogen generators need to be located in an area with proper ventilation in order to immediately disperse this waste gas and to prevent it from coming in contact and interacting with other gases and/or chemical compounds.

To reduce the risk of harmful interactions, nitrogen generators should be installed as close to an exterior wall as possible, so that the waste gas can be dispersed out doors or in a wide-open, ventilated space.

Use Safety Relief Valves
Under all circumstances safety pressure relief valves must be installed on all pressure vessels.

Install a Pressure Vessel Ventilation System
In the event of a safety relief valve activating due to an over pressurization event sufficient ventilation is required in the vicinity of all nitrogen generator installations to ensure there is no build up of excessive nitrogen levels in the area. A professional nitrogen generator technician will install vent stacks on safety relief valves where required which will ensure that if a safety relief does activate the resultant nitrogen gas stream will be vented to a safe area.

Read Warning and Information Labels
Although nitrogen is an inert gas that doesn't have any adverse reactions with other chemical compounds, warning labels to alert workers of its presence should be prominently displayed on all equipment, vessels, and areas where it's used. That way, workers can take special precautions to maintain proper atmospheric nitrogen levels.

FAQ

Q: What gases are mainly produced by the low-temperature gas plant?

A: The low-temperature gas plant mainly produces liquid oxygen (LOX), liquid nitrogen (LN 2), liquid argon (LAr) and liquid helium (LHe). These gases become liquid at low temperatures for easy storage and transportation.

Q: How is the low-temperature gas produced?

A: Cold gas is produced by cooling and separating the components in the air. Air separation technology typically involves the steps of compression, cooling, expansion, and distillation to separate air into its main components (nitrogen, oxygen, argon, etc.), which are then further cooled to convert into a liquid state.

Q: What are the requirements for the storage and transportation of liquid gases?

A: Liquid gases are usually stored in dedicated cryogenic storage tanks that maintain a low temperature environment and prevent gasification. When transporting liquid gas, a special cryogenic tank truck or container should be used to ensure that the gas will not be vaporized during transportation, and that the relevant transportation safety regulations should be observed.

Q: What is the difference between liquid oxygen, liquid nitrogen and liquid argon?

A: Liquid oxygen (LOX), liquid nitrogen (LN 2), and liquid argon (LAr) are the liquid forms of oxygen, nitrogen, and argon at low temperatures, respectively. The main differences are in their chemical properties and applications:
Liquid oxygen: Mainly used in medical care, rocket propulsion and steel industry.
Liquid nitrogen: It is used for cooling, gas protection, and food freezing.
Liquid argon: Used for steel manufacturing, welding, and low-temperature physics experiments.

Q: How to ensure the quality of the low-temperature gas?

A: Raw material testing: Conduct quality inspection of the air or other raw materials entering the gas plant to ensure no pollution.
Production process control: Strictly control the temperature, pressure and purity in the production process to ensure that the gas produced meets the standards.
Regular maintenance and inspection: Conduct regular maintenance and inspection of the equipment to ensure its normal operation and prevent quality problems.
