Vents to flare and to atmosphere are required on pig launchers. Venting to flare for depressurization of the pig launcher can be achieved using bypass on the relief valve. For maintenance, when pig is not in operation it can be vented to atmosphere.

Jul 6, 2021 · For pigging at locations not equipped with a flare or ECD, use a portable flare/ECD unit. Recover the pigging vapors with a portable vapor recovery unit (VRU) compressor and send the gas/vapors to the pipeline system.

In pipeline transportation, pigging is the practice of using pipeline inspection gauges or gadgets, devices generally referred to as pigs or scrapers, to perform various maintenance operations. This is done without stopping the flow of the product in the pipeline. [1][2][3]

Aug 22, 2002 · We are investigating installing an isolation device in Flareheader to aid gas recovery. Isolation device is likely to be an in-line buckling pin, with a pressure control valve in a by-pass for upstream pressure control.

» There must be a physical barrier to the pig leaving the line if it is not in the intended position when opening the launch housing. » Propellant and production fluidventing must take the intended route (to flare if toxic or flammable gases) and not vent to the destination filler/tank. » Ensure all valves, gauges and regulators are in proper

• A Flare System is an arrangement of piping and specialised equipment that collects hydrocarbon releases from relief valves, blowdown valves, pressure control valves and manual vents and disposes of them by combustion at a remote and safe location • A gas flare, or flare stack, is a gas combustion device used in industrial plants

Operating a pig launcher / receiver is a high risk event with people involved and at the same time safe operation depends on these people. Mechanical interlocks take out the human factor of possible mistakes and guide the operator through a safe pre-determined sequence.
