Step into the ring, production managers, because OSY just dropped the February inventory and it’s throwing absolute haymakers. If your gas stream is carrying more unwanted liquid than a soggy sandwich, you’re cruising for a bruising—and your flare stack is usually the one that pays the price. We’re talking about high-pressure Flare Knockout Drums so over-engineered they make your current equipment look like it’s shadowboxing in the dark. From 5 BBL scrappers to 200 BBL heavyweights, this lineup isn’t just “available”—it’s ready to deliver a total technical knockout to your liquid carryover problems before the regulator even rings the bell.
