Nitrogen Purging Services in Jubail
After a Jubail turnaround, units cannot come back online until air is out of the system. We purge to the oxygen target and prove it.
Purging Jubail units at both ends of a shutdown
Olefins, polymer and refining units in Jubail Industrial City must be gas freed before they are opened and inerted before hydrocarbons go back in. Nitrogen purging in Jubail covers both ends of the shutdown, with measured targets agreed with operations and readings recorded at each sample point.
We purge to a measured target. The system volume, purge method, injection and vent points and the oxygen or hydrocarbon limit are agreed before nitrogen is introduced.
Most nitrogen purging jobs in Jubail are part of a wider joint repair, so the same crew can also handle bolt torquing in Jubail and the other services below. For methods, equipment and standards, see our main nitrogen purging services in KSA page.

Can you purge several Jubail units in parallel?
Yes. We size nitrogen supply and crews to the start-up schedule so several systems can be purged at the same time.
What oxygen level do you purge to in Jubail?
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.
Can you supply nitrogen for jobs in Jubail?
Yes. We arrange liquid nitrogen with vaporisers for large volumes or cylinder packs for smaller systems, or use the supply already on site.
