Flare Knockout Drum Rental Alberta, SK, BC and Western Canada
A flare knockout drum sits between production equipment and the flare stack to help remove liquids and slugs from the gas stream before combustion. This helps protect the flare stack, reduce carryover risk, and support more stable flaring during temporary production, well testing, flowback support, separator service, and other oilfield operations.
OSY knockout rentals can be supplied as standalone units or bundled with flare stacks, separators, and vapour-tight tanks when the site needs a more complete temporary production or flaring package.
Knockout Drum Rental Options for Temporary Oilfield Operations
Production Knockout Drum Rental
OSY has field-ready production knockout drums ready for dispatch. A production KO drum helps remove free liquids and slugs from the gas stream before the flare or combustor, supporting more stable combustion and helping protect downstream equipment.
Skidded Knockout Drum Rental
Skidded units are commonly selected when equipment needs to move between locations or when site layout changes. Enclosed and heated configurations are available on selected units for cold-weather operations and component protection.
Sour Service Knockout Drum Rental
Some units include internal coating options such as Devoe 253, depending on build and service history. If sour service capability is required, provide the service conditions so OSY can confirm a suitable knockout drum rental option.

How Flare Knockout Drums Work
A Simple Look at Knockout Drum Function
A flare knockout sits upstream of the flare stack. Wet gas enters the vessel, flow slows down, liquid droplets fall out by gravity and collect in the bottom, and cleaner gas exits toward the flare. This helps protect the flare tip and supports stable combustion.
For a complete rental setup, OSY can pair knockout drums with portable flare stacks, separators, and vapour-tight tank packages.

Regulatory References for Site Review
Knockout drums can be part of a broader flaring, venting, storage, or facility setup. Operators should confirm the requirements that apply to their site, equipment, fluids, event type, and jurisdiction. OSY can support rental equipment availability and package coordination, while final compliance, engineering design, approvals, and reporting remain the operator’s responsibility.
Knockout Drum Rentals - Frequently Asked Questions
Do flare knockout drums require secondary containment?
Containment requirements depend on the jurisdiction, whether the equipment is aboveground or underground, the materials handled, whether the KO is part of an active process, and whether it is being used for storage. Operators should review the applicable AER requirements and site-specific containment expectations before operation.

Can a knockout drum also function as a pop tank for emergency relief?
A KO may serve emergency relief functions only when it does not impede relief, is adequately sized for the released liquid, and meets the applicable flaring, venting, storage, and facility requirements. OSY can help confirm rental availability, but the operator’s engineering team must confirm whether a specific KO configuration is suitable for that purpose.
What information do you need from me to confirm a KO drum rental?
You can contact OSY even if you do not have every detail ready. To help confirm a suitable knockout drum rental faster, it is useful to share the project location, target on-site date if known, expected duration, tie-in sizes if available, operating pressure requirement, expected liquid carryover or slug volume, liquid type, and whether you may need a heated, enclosed, coated, skidded, or sour-service-capable unit.
These details are helpful for rental availability and dispatch planning, but they are not mandatory to begin the discussion.
How fast can OSY mobilize a knockout drum package?
Mobilization depends on inventory, unit configuration, trucking, site location, and the required accessories. If you have a target on-site date, send OSY your location, tie-in sizes, expected slug volume, pressure requirement, and any package requirements so dispatch can confirm timing.
Can a KO connect to a VRU or scrubber system on site?
A KO can be incorporated with other site equipment when the connections, pressure, service conditions, drainage, and process requirements are suitable. If a VRU, scrubber, separator, or other upstream equipment is involved, provide the process details and tie-in requirements so the rental package can be reviewed against your site plan.
Where should a KO drum be placed relative to the flare stack on a rental site?
The KO drum is normally placed upstream of the flare stack so it can remove liquid carryover before gas reaches the flare. It should be positioned on a stable surface with safe access for draining, supported lines, appropriate separation from heat and traffic, and drainage routed according to the site’s containment plan and operator requirements.
What is the function of a knock-out drum?
A knock-out drum, also called a flare knockout or KO drum, removes liquids and slugs from gas before the flare or combustor. This protects the flare stack and helps the flame burn more cleanly and consistently. In rentals across Alberta, Saskatchewan, and BC, KO drums are placed upstream of the flare to catch condensate, water, and entrained droplets that could otherwise contribute to smoke, flame instability, or equipment damage.
How does a flare knock-out drum work?
A flare knock-out drum slows the gas stream so liquids drop out and collect in the vessel while gas continues toward the flare. In operation, wet gas enters the KO, bulk liquids disengage by gravity, finer droplets can coalesce, and cleaner gas exits to the flare stack. Proper sizing, drainage, liquid level management, and upstream separation help reduce carryover.
Can knockouts be rented with flare stacks, separators, and tanks?
Yes. OSY often supplies knockouts with flare stacks, separators, and vapour-tight tanks when a site needs a more complete temporary production, testing, or flaring package.
