Do I need to design my flare for 100% smokeless capacity?2020-07-21T15:29:45+02:00

Typically no. Usually, the emergency and/or fire cases are not required to be smokeless for the entire capacity. Normally, the smokeless capacity will be sized for the continuous and routine flaring or portion of the overall capacity (For example 20 % max flow rate). This helps optimize the design and lower costs.

What information do I need to provide to size a flare?2020-07-21T15:27:33+02:00

To size a flare, we will need to know, available pressure (at flare inlet), Max Temperature of the stream, Average molecular weight of the stream (Yet better, flare gas composition), and flow rate (Mass flow rate is preferred) for each stream. (In short, Pressure, MW, Temperature and Flow rate as a minimum).

Other information, could be the plant’s limits (radiation limits and other environmental requirements), preferred structure type (Self-supported, Guy-wired or derrick supported)

Can I use a continuous sparking device instead of a pilot?2020-07-21T15:27:08+02:00

No. according to the normative “flares shall be operated with a flame present at all times” and, “the presence of a flare pilot flame shall be monitored using a thermocouple or any other equivalent device to detect the presence of a flame.”

When using the flame arrester, do I also need to send purge gas to the flare system?2020-07-21T15:26:46+02:00

Flame arrester only protects what is upstream of it and thus does not protect the flare system. Therefore, Samia Italia recommends using purge gas to ensure that oxygen will not enter through the flare tip.

What is the flame arrester?2020-07-21T15:26:33+02:00

A flame arrester is a passive device which is used to prevent a flashback from propagating further upstream in the flare header

Does the flare tip require continuous steam or air injection?2020-07-21T15:26:16+02:00

Yes, since assist medium injection components are near the flame, a minimum continuous flow of steam, air, or other assist media is usually required to protect the equipment from high temperatures.

What methods are available for smokeless operation?2020-07-21T15:26:03+02:00

There are many methods for smokeless operation (Reduce the combustion smoke), there are four main smokeless methods are Air-Assisted, Steam-Assisted (Steam Injection), gas/fuel injection, and Sonic (High Pressure) flaring.

Which type of pilot ignition system is better; Flame Front Generator or High Energy Ignition?2020-07-21T15:25:46+02:00

Both systems are very reliable; though, you may favor the advantages of one system over the other, depending on your need.

The Flame Front Generator (F.F.G) is easier to access for maintenance, as all operating components are at the base, and it has the option of a manual ignitor at base; yet, it needs regular maintenance to ensure reliable operation.

The High Energy Ignition (H.E.I) is easier to operate and requires a less complex piping system; nevertheless, components must be replaced over time, requiring a shutdown of the flare.

What inlet gas pressure is required for the HP / Sonic flare system?2020-07-21T15:25:32+02:00

The required flare gas pressure for Sonic Flare systems will depend on the application. Gas production or processing applications typically require 3.5 to 5.5 bar. In this case, Samia Italia recommends a sonic flaring system, which would potentially eliminate the needs of any smokeless system. Petrochemical applications typically require 1.3 to 1.7 bar. In this case, Samia Italia recommends using a ground flare system.

Can the life expectancy of the flare tip be improved by using a higher-grade metal than AISI SS 310S?2020-07-21T15:25:20+02:00

Usually, no. Flare tips most often fail because of distortion and cracking due to differential heating and cooling, not pure corrosion, or strength loss at temperature; features of some higher alloys.

What is a Knock out drum?2020-07-21T15:25:04+02:00

Knockout drums (also known as relief drums or flare or vent scrubbers) removes any liquid droplets that carry over with the gas relief sent to the flare. Most flares require that the particle size be reduced to a minimum of less than 300 μm. Normative suggests sizing for liquid droplets between 400 and 500 μm. Most knockout drums are horizontal with a length-to-diameter ratio of 2 to 4. A horizontal knockout drum must have a diameter large enough to keep the vapor velocity low enough to allow entrained liquids to settle or drop out.

Knockout drums operated at atmospheric pressure should be sized to handle the greatest liquid volume expected at the maximum rates of liquid buildup and pump out. Onshore, it is recommended to take 20% of the maximum potential liquid stream and provide a 10-minute liquid holdup. An emergency disposal pile is recommended to dispose of the liquid, and a seal in the pile is recommended to contain the backpressure in the drum.

What is the purpose of the liquid seal (Water Seal)?2020-07-21T15:24:51+02:00

A liquid seal (Water Seal) is used to create a water seal barrier between the flare stack and the upstream flare header.

Samia Italia recommends using the liquid seal when there is a possibility of oxygen in the gas stream or excessive flame propagation; or when the purge gas may not be reliable or adequate.

What is the difference between the buoyancy (Gas Seal) seal and the velocity seal?2020-07-21T15:24:38+02:00

Samia Italia utilizes buoyancy and velocity seals to keep air from flowing back into the flare header and to reduce the amount of required purge gas.

Buoyancy seals are separate, larger drums which use the difference between the buoyancy of air and the buoyancy of purge gas to seal the flare from the air.

Velocity seals increase the velocity of purge gas within the seal thus that air is pushed out and prevented from entering the system below the seal. Compared to a gas seal, a velocity seal is less complex, needs less maintenance, and has a lower impact on the stack design; though, the gas seal offers a greater reduction in purge gas requirements than the velocity seal.

Which one should I use to purge my flare, fuel gas or Nitrogen?2020-07-21T15:24:24+02:00

Samia Italia’s flares are compatible with both fuel gas and Nitrogen gasses. Local environmental requirements and availability of nitrogen or fuel gas at the site usually help determine the specific purge medium.

What is the purge gas?2020-07-21T15:24:11+02:00

The purge gas is injected into the relief header at the upstream end and at the major branches to maintain a hydrocarbon-rich atmosphere in each branch, into the off-plot relief system, and into the flare stack. The gas volume typically is enough to maintain the following velocities. The oxygen concentration must not be greater than 6% at 7m inside the tip. When there is enough PSV leakage or process venting to maintain the desired backpressure, no purge gas is injected.

How can I ensure my facility is compliant with the latest environmental standards?2020-07-21T15:23:57+02:00

Contact Samia Italia and our experienced engineers would guide you step by step to study and improve the facility environmental standards up to the desired/required levels.

Can a flare pilot operate under harsh wind and rain conditions?2020-07-21T15:23:41+02:00

Yes. Temperature, purge gas, flame impingement, environmental conditions, and weather events are just a few of the various extremes that flare pilots are vulnerable to. The Samia Italia’s flare pilots are proven to endure winds up to 275 km/h and 132 cm/h of Rain.

What is a flare pilot?2020-07-21T15:23:28+02:00

A pilot is a critical component of a flare system that ensures proper ignition of waste gas streams. Without a pilot, toxic gases could potentially vent to the atmosphere.

What is a Flare?2020-07-21T15:23:13+02:00

A flare system is a safety device which collects and discharges gas from atmospheric or pressurized process components to the atmosphere to safe locations for final release during normal and emergency operations. In vent systems, the gas exiting the system is dispersed in the atmosphere. Flare systems generally have a pilot or ignition device that ignites the gas exiting the system since the discharge may be either continuous or intermittent. Gas-disposal systems for tanks operating near atmospheric pressure are often called atmospheric vents or flares, and gas-disposal systems for pressure vessels are called pressure vents or flares. A scrubbing vessel should be provided to remove liquid hydrocarbons.

Do Flares (Flaring), Burners and other Combustion equipment go against green initiatives?2020-07-21T15:22:59+02:00

No, in fact, combustion systems are designed to decrease the environmental impact of human activities. Samia Italia’s equipment ensures that companies around the world comply with the latest environmental and safety regulations by improving the efficiency and decreasing output of carbon monoxide (CO) and other volatile organic compounds (VOCs), like nitrogen oxides (NOx), sulfur oxides (SOx).

What is combustion?2020-07-21T15:22:17+02:00

To put it simply, combustion is the process of burning. Combustion, or burning, is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, typically atmospheric oxygen that produces oxidized, often gaseous products, in a mixture termed as smoke. Combustion in a fire produces a flame, and the heat produced can make combustion self-sustaining.
