Frequently Asked Questions

Flare Systems & Knock-Out Drums in Saudi Arabia — Common Questions

What API standards apply to flare systems supplied in Saudi Arabia?

The primary standards are API 521 (Pressure-Relieving and Depressuring Systems) for system sizing and API 537 (Flare Details for General Refinery and Petrochemical Service) for flare hardware design. Saudi Aramco also requires compliance with SAES-J-702 (Flare and Blowdown Systems) and SAES-J-700 (Fired Heaters) for associated equipment. All Gulf Union Ozone flare packages include the relevant calculation sheets and data books.

How do you ensure safe liquid removal before the flare tip?

We supply knock-out drums designed to API 521 Section 5.5 criteria, sized for worst-case two-phase flow. Horizontal KO drums include inlet vane distributors and mist eliminators; vertical units use cyclonic separation. Liquid seal drums are set to a minimum 25 mm water seal per API 521, preventing flashback from the flare header. All KO vessels include level gauges and high-level alarms.

Can Gulf Union Ozone supply emergency replacement flare tips during a plant turnaround?

Yes. We hold common-size pipe flare tips (6", 8", 10", 12") and pilot assemblies in our Jeddah warehouse and can dispatch within 24 hours. For custom or large-diameter tips (≥16"), we can expedite fabrication on an emergency basis. Contact our technical team with the existing tip datasheet and we will confirm availability and lead time within two hours.
