A horizontal knockout drum must have a diameter large enough to keep the vapour velocity low enough to allow entrained liquids to settle or drop out. All flare systems are designed to include a liquid knockout drum.

  • Design of a vapor-liquid separator drum (or knockout pot

    Sep 09 2005 · The vapor travels upward at a design velocity which minimizes the entrainment of any liquid droplets in the vapor as it exits the top of the vessel. The size a vapor-liquid separator drum (or knock-out pot or flash drum or compressor suction drum) should be dictated by the anticipated flow rate of vapor and liquid from the drum. The knockout drum slows down gases and allow liquids to fallout of the gas stream. Both horizontal and vertical design are common configuration for knockout drums. These vessels can commonly be referred to as flare knockout drums flare drums flash drums knockout pots and compressor suction drums.

The gas and oil usually leave the vessel through the same outlet to be processed by other equipment. The water is removed in gas processing and lng production large diameter vertical compressor suction drums and vapor/liquid separators are common. the liquid level in these vessels are controlled above the bottom tangent line resulting in storage of large amount of flammable liquid inventory below high liquid level which often is in excess of threshold volume for pool fire.

  • A quick guide to compressor suction knockout drum sizing

    Compressor suction knockout drums are used to remove liquid droplet carryover in gases and to thus protect the downstream equipment usually a reciprocating or centrifugal compressor. Most compressor suction knockout drums are arranged vertically. There are several ways to size a vertically oriented For optimum separation performance compressor knock-out drums must be properly designed and sized with appropri-ate mist eliminator elements in correct configur s taking into account many factors. In multistage compressor installa-s the proper knockout drum design is seldom the same for all stages.
