The released gases and liquids are routed through large piping systems called flare headers to the flare. The released gases are burned as they exit the flare stacks. Commonly, flares are equipped with a vapor-liquid separator (also known as a knockout drum – KOD ) upstream of the flare to remove any large amounts of liquid that may accompany ...

Flare header. The network of pipes that runs through the plant and into the flare’s liquid knockout drum is called the flare header. It collects discharge from safety valves and control valves in the plant.

• Gas is collected in piping headers and delivered to a flare system for safe disposal • A flare system can consist of multiple flares to treat the various sources of waste gases i.e. HP and LP Flares, Cold Flares, Wet and Dry systems • Most flaring processes usually take place at the top of a stack by burning of gases with a visible flame

Flaring is defined as a process of controlled burning of exhaust gases which generates heat and noise. Flaring is a common practice in oil/gas exploration, production and processing operations. A flare system consists of a flare stack and pipes that feed gas to the stack.

2024年8月9日 · Flare Header: The pipeline collecting relief valve discharges, vents, etc., and directing them to the flare stack. Knockout drum: Takes out liquids from the gas stream, before it enters the flare header.

Define the need for plant flares in any plants. Describe the different components of a typical flare system. Discuss the limitations and hazards associated with operating flare systems. Discuss maintenance requirements of flare systems. Flares – What is function of flares?

Flare headers are a vital link from the process units to the flare stack. In an upset or shutdown condition, large amounts of gas, vapour and even liquids can be pushed through this piping.

Below animation shows the basic process flow for a flare system. Each element is briefly discussed afterwards. Waste gases from vents, blowdown gases released from pressure relief devices, are sent to the flare stack through the gas collection header. This piping should be designed to have minimum pressure drop.

Flare purge gas means gas introduced between a flare header's water seal and the flare tip to prevent oxygen infiltration (backflow) into the flare tip. For a flare with no water seal, the function of flare purge gas is performed by flare sweep gas.

gencies at refineries and petrochemical plants. A typical flare system consists of a flare header, a liquid knockout drum, a flashback seal drum, a flashback prevention section, and flare pilots (Figure 1). Flare header. The network of pipes that runs through the plant and into the flare’s liquid knockout drum is called the flare header.
