Advanced Membrane / PSA Technology • High-Pressure Nitrogen Pumps • Rugged Off-Road Chassis • Designed for Well Stimulation, Purging & Enhanced Recovery
The oilfield nitrogen generation truck represents a transformative leap forward in how oil and gas operators supply high-purity nitrogen at the wellsite. Manufactured by Henan Vance Petroleum Machinery Co., Ltd., this fully self-contained mobile unit integrates advanced membrane or PSA (Pressure Swing Adsorption) nitrogen generation technology, high-pressure reciprocating pumps, precision digital controls, and a heavy-duty off-road chassis into a single deployable platform. Rather than relying on costly liquid nitrogen deliveries, hazardous cryogenic storage, or unpredictable third-party supply chains, operators can now produce unlimited, high-purity nitrogen on demand—directly at the point of use—24 hours a day, 7 days a week.
Traditional nitrogen supply methods impose significant logistical burdens on oilfield operations. Liquid nitrogen must be manufactured at centralized plants, transported in specialized cryogenic tankers over long distances, and stored in vacuum-insulated vessels that require constant monitoring and venting. Each link in that supply chain introduces cost, delay, and safety risk. The nitrogen generation truck from Vance Petro eliminates every one of those vulnerabilities. By separating nitrogen from ambient air on location, the unit delivers a continuous, pressure-stable supply of gaseous nitrogen at purities up to 99.9% and working pressures exceeding 10,000 PSI—with no evaporation losses, no boil-off waste, and no dependency on external suppliers.
For modern oilfield operations—including well stimulation and fracturing support, wellbore purging and inerting, high-pressure leak and integrity testing, coiled tubing nitrogen lifts, enhanced oil recovery (EOR) gas injection, and pipeline commissioning—the nitrogen pumping truck has become an indispensable asset. Its ability to generate and inject nitrogen continuously, at precisely controlled flow rates and pressures, makes it the preferred solution for operators who demand reliability, safety, and operational independence.
Hollow-fiber membrane or multi-tower PSA systems deliver nitrogen purities from 95% to 99.999% directly from ambient air — unlimited supply with zero moving parts in the separation stage.
Heavy-duty multi-stage reciprocating compressors and intensifier pumps with forged alloy steel fluid ends, ceramic-coated plungers, and variable-speed drive for precise pressure and flow control.
ASME/PED-certified high-pressure buffer vessel cascade (2–6 m³) enables instant high-volume injection for kick-off, displacement, and emergency inerting operations.
Siemens/Allen-Bradley PLC with 12" touchscreen HMI, real-time data logging, trend analysis, alarm management, and optional SCADA integration.
6×4 / 6×6 / 8×8 heavy-duty off-road chassis with 300–600 HP engine, exceptional payload capacity, ground clearance, and all-wheel-drive traction for oilfield terrain.
Fully enclosed, HVAC-controlled cabin with ergonomic layout, vibration isolation, and noise attenuation for comfortable 24/7 operations in extreme environments.
API 6A, API Q1, ISO 9001, ISO 14001, ASME, CE, ATEX certified. ESD systems, pressure relief, fire suppression, gas detection, and full documentation packages.
Discrete, interchangeable modules for generation, pumping, control, and hydraulics — dramatically reduces MTTR and enables full customization to customer specifications.
