FLARE GAS RECOVERY UNITS
This unit, now installed in a world-scale Olefins Complex in Taiwan, is representative of the type of packaged unit Flaregas designs for this application. In this application a two-stage centrifugal compressor was selected for the 3.5 Te/h capacity with 4.5 Barg discharge pressure requirement. The skid contains all of the compression equipment, including drivers, coolers and controls. Flaregas custom designs these units to be fully integrated with the relief system, and includes all necessary safety measures in both the package design and relief & flare system design. ...

A guy-supported air-assisted smokeless flare. Flaregas air assisted flares are co-axial, with the gas passing to the flare tip in the inner gas riser. The air for smokeless combustion is provided by low pressure air assist fans located at the base of the stack, and conducted to the flare tip in the annular space between the gas riser and the outer air duct. The outer air duct becomes the structural support for the stack, which can be self-supported, guy-supported or supported using a derrick structure – normally depending on the height of the flare Another image of a Flaregas...

This is our series FHP steam assisted smokeless flare tip, with external Flarestream steam injection nozzles arranged on an external ring. This type of flare tip is designed for typical refinery use, where very high efficiency, high smokeless capacity, and very low noise is not a specific design requirement. This is a picture of an FS series high performance smokeless flare tip during fabrication. This style of flare tip uses a totally different type of steam injection. Floanda (internal coanda) nozzles are located in a cone at the top section of the tip. The steam entrains a large quantity...

Burn pits can be designed in various ways. These images illustrate a simple burn pit, with the horizontal burner anchored with a refractory block. The pit is contructed from an excavation, and uses angular gravel for its base material. No provisions have been made to control liquid seepage. This image shows a burn pit burner of a different style – down for maintenance after four years operation. Note the base of the burn pit is a combination of refractory brick and concrete. The excavated bund is lined with gravel, except at the immediate penetration of the burner, where firebrick...

This image shows an elevated staged matrix flare system, installed in refinery service. A significant benefit of putting the burner matrix in an elevated structure is that it becomes more compact since combustion air more easily brought to each of the burners. The plot area taken up by the system is also much reduced. Although most matrix flares use non-assisted burner systems which use the pressure of the waste gas in specially designed high pressure burners to promote smokeless combustion, they can also be designed with assisted (steam or air) burners in cases where the waste gas is only...

Flaregas staged matrix flares are designed to burn very large quantities of gas smokelessly through-out the entire operating range. Smokeless performance is achieved using high pressure, high turbulence burners, arranged in a matrix so that combustion air is available to each burner. These flares can be used to burn a very wide range of gases smokelessly. This grade level unit has a design capacity of more than 3,000,000 lb/h, all flows completely smokeless. It has about 600 burners, arranged in 7 stages. Smokeless turn-down is enhanced by staging the flow to the unit. This ensures that the...

Flaregas designs several different types of ground flares, both enclosed and open pit type. Most enclosed flares of high capacity are rectangular, but cylindrical units are used for lower design capacities. These two images show rectangular design ground flares, 80ft overall length, 20ft wide and 60ft tall approximate flare capacity of this size unit is 50 Te/h These two images show the inside of the ground flares shown above. The burners in this case are steam assisted for olefins service, and the images show the modular ceramic fiber block used for insulation of the inside walls of the...

Flaregas designs and manufactures all types of elevated flare systems guy-supported, self-supported, derrick supported, clustered, de-mountable, steam, gas or air assisted, sonic and non-assisted This is an image of a clustered flare, with multiple gas risers and flare tips. The stack is self-supporting, with both steam and non-assisted flare tips Although Flaregas does not have a construction division, our engineers can provide services in an advisory capacity, providing guidance during erection, start-up and/or operator training. Our engineers will discuss erection methods with...
