What is a condensate knockout?

Condensate chambers, also referred to as seal pots, condensate pots and sometimes knockout pots, are used in a variety of industries to trap and hold foreign materials that may accumulate in gaseous service lines. These condensate pots periodically become full and have to be drained off.

What is Knock out Tank?

A Knock-out (KO) drum consists of a vertical vessel specially designed to separate vapor and liquid from a two-phase process flow. Inside you’ll find an inlet diffuser and de-entrainment mesh pad designed to maximize the collection of liquid contained in the vapor as it travels to the top of the vessel.

What does a knockout drum do?

Flare Knock Out (KO) drums, pots, or vessels are a key component of the flare system and used to slow down gas flow by creating a pressure drop, allowing liquids and condensate to fall out of the vented gas stream ahead of combustion in the flaring system.

How does a vapor-liquid separator work?

In vapor-liquid separators gravity is utilized to cause the denser fluid (liquid) to settle to the bottom of the vessel where it is withdrawn, less dense fluid (vapor) is withdrawn from the top of the vessel.

What is the difference between separator and knock out drum?

Knock-out drums are used in the flare systems or just before compressors for safety concerns and product recovery. Separators have broad applications. They are extensively used in processing plants to separate oil, water, and gas streams for sending for further processing.

What is feed surge drum?

A surge tank (or surge drum or surge pool) is a standpipe or storage reservoir at the downstream end of a closed aqueduct, feeder, dam, barrage pipe to absorb sudden rises of pressure, as well as to quickly provide extra water during a brief drop in pressure.

What is compressor knock out drum?

Compressor 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.

What are the types of separators?

There are two types of “phase categories” that separators can be grouped within:

  • Gas/liquid two-phase separator.
  • Oil/gas/water three-phase separator.

How does a Schoepentoeter work?

Schoepentoeters in Vessels Typically a schoepentoeter inlet device functions by decreasing the momentum of the incoming feed stream. Reduced momentum gives ample residence time to the incoming fluids, enough to allow for the removal of liquids and solids present in the feed.

What is surge tank in hydro power plant?

Surge tanks are applied in hydropower plants with long water conduits to reduce pressure forces during the acceleration of the large water masses. They are constructed as intermittent water reservoirs close to the turbines, either with open access to atmospheric air or as a closed volume filled with pressurized air.

What is a surge drum refrigeration?

The surge drum on a flooded evaporator performs various important functions. They are: (1) To separate the liquid out of the gas returning from the evaporator; allow the gas to pass to the compressor through the suction line; to return the liquid to the evaporator for re-circulation.

What is a blowdown drum?

A separate collection vessel intended to receive a periodic or emergency discharge of liquids, liquid reaction mass, or slurries from a number of process vessels, reactors, or equipment items.
