MEMBRANE NITROGEN SYSTEMS
Compact and fast-starting systems for oil and gas, offshore, mobile and selected low-to-medium purity duties.
These are reference ranges from existing materials. Maximum flow and highest purity may not coincide. Confirm the model, feed conditions, dew-point basis and optional configuration in the project datasheet.
ENGINEERING NOTES
The following establishes a technical discussion framework. Final performance, scope, certification and acceptance criteria are defined in the agreed technical specification.
Clean compressed air enters hollow-fibre membrane modules. Faster-permeating oxygen and water vapour pass through the membrane wall while nitrogen-rich gas exits the opposite end. With no adsorption-vessel cycling, the system supports fast starts and compact layouts.
Concept gas path. Project engineering defines vent handling, valve timing, sampling and safeguards; this is not a construction drawing.
ENGINEERING SCHEMATIC
Fast gases permeate the hollow fibres while nitrogen-rich retentate continues to the process.
Systems can be configured as indoor cabinets, skids, containers or mobile packages, with instrumentation and controls selected for hazardous-area classification, ambient conditions, corrosion protection and project standards.
Selection should not be price-only. Higher purity often favours PSA, while rapid start, lower purity, low weight or limited space can favour membrane technology. Compare feed-air demand, energy, maintenance, environment and lifecycle cost.
Membrane purity and recovery are linked. Raising purity normally reduces product recovery and increases feed air per unit of nitrogen, so purity should never be specified without flow and energy consequences.
High temperature, liquid water, oil aerosol and contaminants affect membrane performance. Offshore, desert and cold-climate packages require checks for inlet-temperature control, drainage, corrosion protection, insulation, heat tracing, ventilation and start-up procedure.
Mobile packages combine transport loads, lifting points, chassis, vibration, hose interfaces, quick connections, diesel or electric drive, earthing and hazardous-area requirements. Maximum practical integration should be tested before dispatch.

EQUIPMENT & DELIVERY
Air enters the membrane bank. Faster-permeating gases leave on the permeate side, while nitrogen-rich gas exits the product side. Flow, purity, pressure and temperature interact; filtration and feed conditions must follow the membrane supplier’s data.

EQUIPMENT & DELIVERY
A container combines equipment and interfaces in an engineered package. Check heat rejection, ventilation, drainage, noise, maintenance and electrical isolation. Transport dimensions and lifting arrangements require a separate review; this concept has no assumed dimensions.

EQUIPMENT & DELIVERY
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.

PAGE FAQ
It is often selected for low-to-medium purity and high-flow duties; the final range depends on module type, temperature, pressure and recovery.
Yes. Liquid water, oil aerosol, particles and temperature must be controlled to protect the modules and stabilise performance.
Compare purity, product flow, feed air, energy, footprint, start-up, maintenance, environment and total cost at the same duty.
