Engineering

Airrestore

- Purge reducing device

- Designed to minimize air

infiltration into the flare tip

with significant purge gas

saving

General presentation

13

Engineering

Molecular seal

-Designed to minimize air

infiltration into the flare system

- Even when the purge gas is

interrupted, the molecular seal

provides protection for a period of

time

- The protection from Airrestore

and similar devices is immediatly

lost if the purge gas flow is

interrupted.

Engineering

Knock Out Drum

- Separates liquid from gas

- Increases flare tip life

- Prevents or reduces smoke because of

reduced liquid in the flame

- Prevents liquids from being discharged to

atmosphere (fire)

General presentation

15

Engineering

Liquid seal

- Commonly incorporated into the flare stack base,

the liquid seal is used to provide positive pressure

on the flare gas relief header and to be a positive

flame arrestor in the event a flashback occurs in

the flare stack.

-The internals are specially designed to ensure a

stready flow of gases to the tip thus increasing the

maximum smokeless capacity of the flare without

supplemental energy.

-The liquid seal internals also decrease the noise

caused by combustion at the flare.

Maintenance

Most major maintenance has to occur during a Shutdown

Consideration for inspection, repair or replacement

- Tip

- Pilots

- Thermocouples

- Clean/ check fuel and FFG piping for leaks and pluggage

- Critical instrumentation

- Stack (feeder, Platform and ladders)

- Guy wire connections at stack (cables tension, lubrication and

Verticality)

- Molecular seal

- Water seal

- KO Drum

- Aviation lights
