Is a important safety device used in refineries and petrochemical facilities. They safely burn excess hydrocarbon gases which cannot be recovered or recycled. Excess hydrocarbon gases are burnt in the flare systems in an environmentally-sound manner, as an alternative to releasing the vapour directly into the atmosphere.
During flaring, excess gases are combined with steam and/or air, and burnt off in the flare system to produce water vapour and carbon dioxide. The process of burning these excess gases is similar to the burning of liquefied petroleum gases (LPG), which some of us use as fuel for home cooking.
The use of flares is minimised to the extent that is possible. However, flaring can occur during a start-up and shut-down of any of our facilities for maintenance, and also during unplanned operational interruptions such as power outages.
When there is flaring promptly inform the neighbouring companies and Government agencies.
There are generally two types of flares that we use at manufacturing facilities..
A flame or a glow..
When you see flaring, please be assured that flares play a key role in keeping refineries and chemical plants running safely.
Gas Blower - Device for blowing air to flare system.
Flare System - A system that safely disposing of waste gases through the use of combustion.
Flare Stack - Is an elevated vertical stack found on oilwells or oil rigs, and in refineries, chemical plants and landfills used for burning off unusable waste gas or flammable gas and liquids released by pressure relief valves during unplanned over-pressuring of plant equipment.
Flare Tips - Structure at top of the flare play the role to keep an optimum burn and control over all flow rates, which results in a cleanercombustion. The design of the tip makes sure that the tip does not come into contacting with the flame making the tips reliable and long lasting.
Ignitions system - Is a system use to ignite the flare of flare systems. Normally this system designed to ignite the flare quickly the first time, maintain combustion and reignite rapidly to prevent industrial hazards and personal injury while protecting the environment.
Knockout Drum - Is a drum installed near the flare base, and serves to recover liquid hydrocarbons, prevent liquid slugs, and remove large liquid particles from the gas streams released from relief system.
Support Structure - Structure which designed to withstand local wind condition for flares. Three types available self-supported, Guy-wire supported and Derrick supported.
Windbreaker - A windbreaker is structure uses to prevent the wind from extinguishing the flames which located at flare tip. It serves also to hide the flames.
