Terminal – Petrochemical facility degassing of storage tank of gas sphere

Degassing of storage tanks and gas spheres. Mobile, sustainable and economical degassing solutions across West-Europe - 24/7

At Group AQ, we provide mobile cryogenic degassing services to support maintenance, inspection and modification works on storage tanks and gas spheres. Our technology delivers a complete degassing solution without combustion, ensuring maximum safety, zero NOx emissions, minimal VOC emissions, and full or partial recovery of high-value product, which is returned to the client after execution of the works.

Operating from strategic locations near Antwerp and Rotterdam, our teams offer rapid on-site support across West-Europe, minimizing downtime and ensuring full regulatory compliance.

The challenge

Before maintenance, inspection or modification activities can take place, storage tanks and gas spheres must be safely and effectively degassed. Operators are increasingly confronted with:

  • Strict safety and environmental requirements
  • Limitations of conventional degassing methods involving combustion
  • VOC and NOx emission constraints
  • Pressure to reduce downtime and overall maintenance cost

These challenges require degassing solutions that are safe, sustainable, compliant and economically viable, without compromising operational planning.

The most sustainable degassing solution on the market

Group AQ specializes in cryogenic degassing, using liquid nitrogen to remove and recover vapors without combustion. Instead of burning hydrocarbons, vapors are condensed into liquid form and safely captured. Key benefits include:

  • No combustion and no NOx emissions
  • Up to 99.9% VOC reduction
  • Full or partial recovery of valuable product
  • Lowest possible environmental impact

Cryogenic degassing is widely recognized as the most sustainable degassing technique available for storage tanks and gas spheres.

Mobile degassing for tanks and gas spheres

Every installation is different. That is why Group AQ works exclusively with fully mobile degassing units, allowing us to operate directly at your site.

Our mobile solutions are ideally suited for:

  • Storage tanks and tank farms
  • Pressurized gas spheres
  • Petrochemical and chemical facilities
  • Terminal maintenance and shutdown projects

Mobile deployment ensures fast start-up, flexible capacity, and minimal disruption to ongoing terminal or plant operations.

Economical degassing with full product recovery

Cryogenic degassing is not only environmentally responsible, but in many cases also the most economical degassing solution. By condensing vapors instead of destroying them, valuable product can be recovered and reused.

This results in:

  • Lower disposal and treatment costs
  • Reduced product losses
  • Shorter project durations
  • Optimized maintenance and shutdown planning

Combined with our structured execution approach, clients benefit from reduced downtime and lower total project cost.

24/7 degassing with fast on-site support

Maintenance windows are often tight and inflexible. Group AQ provides 24/7 degassing services, including support during shutdowns, weekends and urgent situations.

Our structured workflow ensures:

  • Fast technical assessment
  • Clear planning and execution strategy
  • Rapid mobilization of mobile degassing units
  • Safe, controlled and monitored degassing
  • Full documentation for compliance and audits

With teams experienced in complex petrochemical environments, projects are executed efficiently and safely from start to finish.

Safety and compliance first

Safety is never optional. All Group AQ degassing operations are performed in accordance with internationally recognized standards, including:

  • ISO 9001 – Quality management
  • ISO 14001 – Environmental management
  • VCA – Safety, health and environment
