Nitrogen Purging Services in Ras Tanura
Before a terminal line at Ras Tanura is cut or a refinery unit restarts, the gas has to go. We displace it with nitrogen and measure the result.
Displacing terminal lines in Ras Tanura
Long crude and product lines between Ras Tanura tank farms and jetties hold large volumes of vapour. Nitrogen purging in Ras Tanura displaces that vapour ahead of cutting and tie-ins, and inerts refinery systems before start-up, with readings taken at both ends of each line.
Pressure purging reaches branches and dead legs, flow-through displacement clears long lines efficiently, and dilution suits vessels and tanks.
Most nitrogen purging jobs in Ras Tanura are part of a wider joint repair, so the same crew can also handle bolt torquing in Ras Tanura and the other services below. For methods, equipment and standards, see our main nitrogen purging services in KSA page.

How do you purge long terminal lines at Ras Tanura?
Usually by flow-through displacement, feeding nitrogen at one end and sampling at the other until the target is met.
Can you supply nitrogen for jobs in Ras Tanura?
Yes. We arrange liquid nitrogen with vaporisers for large volumes or cylinder packs for smaller systems, or use the supply already on site.
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.
