Nitrogen services

Replacing dangerous or undesirable liquids, vapours and gases in the process units or in the pipelines with nitrogen prevents dangerous work conditions in the hydrocarbon industry and pipeline transportation.

Nitrogen purging and hydrocarbon displacement services help to reduce costs, protect people and nature during process units or pipeline commissioning, remedial repair, decommissioning and abandonment.

CEPS operates several membrane nitrogen units that produce nitrogen from the air directly on the site. This method not only saves nitrogen transportation costs to remote places but can also be used on sites inaccessible to heavy cryogenic nitrogen tanks.

Our engineers can create most effective procedures for any application.

The nitrogen unit specifications

nitrogen purity [%] 95 93 90
capacity [m³/hour] 800 930 1100
discharge pressure [bar] 25 25 9
  • Built into 20′ ISO container
  • Self-powered by integrated electric generator
  • Automatic control of nitrogen purity
  • Monitoring flow, pressure, temperature and nitrogen purity
