Nitrogen Purging Services in Rabigh
The Rabigh complex mixes refining and petrochemical units, each with its own purge requirements. We plan every system separately.
Purging systems in the Rabigh complex
Refining and petrochemical units in the Rabigh complex need gas freeing before shutdown work and inerting before start-up, often with tight oxygen limits on petrochemical systems. Nitrogen purging in Rabigh sets the method and target for each system and proves it with calibrated analysers.
Calibrated analysers confirm each stage, and every reading is recorded so your operations team has proof that the system is inert or dry.
Most nitrogen purging jobs in Rabigh are part of a wider joint repair, so the same crew can also handle bolt torquing in Rabigh and the other services below. For methods, equipment and standards, see our main nitrogen purging services in KSA page.

Do petrochemical units in Rabigh need lower oxygen targets?
Often, yes. The target is set by the unit procedures, and we purge and measure until it is met.
How do you know a purge is complete?
Readings are taken with calibrated analysers at agreed points. The purge is complete when consecutive readings meet the target, and the results are witnessed and recorded.
What oxygen level do you purge to in Rabigh?
The target is set by your site procedures and the next activity. Inerting before hydrocarbons go in commonly aims for a low single-digit oxygen percentage or less, agreed before we start.
