ENGINEERING NOTES

Define the duty before selecting equipment.

The following establishes a technical discussion framework. Final performance, scope, certification and acceptance criteria are defined in the agreed technical specification.

01

Process objective

Nitrogen can reduce oxygen concentration in equipment and tanks, helping limit oxidation, moisture ingress and formation of flammable mixtures. Required purity and flow depend on media, volume, breathing losses, leakage and procedure.

ENGINEERING SCHEMATIC

Chemical inerting control chain

The schematic clarifies the gas path and scope boundaries; final instruments, interlocks and layout follow the project specification.

02

Safety boundary

The owner process and safety teams must define oxygen targets, maximum allowable oxygen, relief path, hazardous area, instrument integrity and interlocks. A nitrogen package does not replace HAZOP or formal safety assessment.

03

Complete configuration

Configure storage, regulation, flow metering, oxygen analysis, off-spec venting, backup connection and DCS communication, with clear boundaries to tanks, headers and field instruments.

04

Blanketing, inerting and purging are different loads

Continuous blanketing follows level change, thermal breathing and leakage. Initial inerting depends on volume and oxygen target. Maintenance purging is driven by the work window and vent route. Calculate separately before applying simultaneity.

05

Online analysis and off-spec handling

Critical inerting duties should define analyser range, calibration, sample conditioning, alarm setpoints, interlocks, off-spec venting and backup changeover. Purity is verifiable only when the sampling point is defined.

06

Materials, seals and media compatibility

Although the generator handles air and nitrogen, downstream interfaces may be exposed to corrosive or hazardous media. Check valves, isolation, materials and backflow protection must be agreed across the system boundary.

EQUIPMENT & DELIVERY

Measurement starts with the sampling point

Purity, residual oxygen and dew point are different specifications. Define the analyte, sampling location and pressure basis before choosing instruments, alarms and off-spec handling. The illustration explains the arrangement and contains no test readings.

EQUIPMENT & DELIVERY

Valve sequencing between the towers

One tower adsorbs while the other regenerates. Valves sequence feed, pressure equalisation, delivery and exhaust. Buffering and off-spec handling must be assessed separately from the process demand, with access and spares planned for the valves.

PAGE FAQ

Answer the critical questions before sizing.

How is nitrogen purity set for chemical duty?

It is set by media, oxygen target, operating procedure and safety study—not one universal value.

Does the nitrogen package replace HAZOP?

No. The package implements confirmed process and safety requirements.

Is backup nitrogen required?

It depends on loss-of-nitrogen consequence, allowable interruption, storage and owner risk criteria.
