During plant start-up, or when an unexpected situation arises causing a buildup of pressurized hydrocarbon gases, the excess gas is vented through a pipe to a cen-tralized location on the refinery grounds. There are many such sources of high-pressure gas in a plant, and for some plants the flares are gathered into a central location in a matrix of flares the size, on average, of one-to-three football fields. The terminus of each pipe rises approximately 6’ - 12’ from the ground. At the top of each pipe is a nozzle in the shape of a spider.High Pressure Flaring SystemsHigh Pressure Flaring SystemBy controlling flame length, ECC technology may enable operators to reduce the height of these fences by 30%. Because a fence cost may repre-sent 30-50% of the overall cost of a multi-point, high-pressure flare system, implementation of ECC would represent a considerable capital expense reduction. Additionally, current controversy re-garding whether or not these flares meet expect-ed combustion efficiency targets of 98% or higher may prompt government officials to impose envi-ronmental regulations to limit hydrocarbon emis-sions that ultimately contribute to ground level ozone issues (smog). The more complete combus-tion (i.e., enhanced mixing) offered by ECC would ensure combustion efficiency targets can be met.The ECC™ SolutionRefineries and petrochemical plants are sensitive to the problems and concerns these flares which, when activated, can cause for neighbors and the surrounding environment. Because flares can cause an extremely bright flash with attendant noise and radiation, they represent one of the primary issues involved in siting new plants. Spe-The Problemcial fences are typically constructed on the periph-ery of these flare fields of up to 25-30’ in height, which represent a considerable cost component of the system itself.Multi-point, high-pressure flares are usually large com-bustion systems that require a fence in the perimeter of a large field to protect personnel and equipment from intense radiation and hide the system from neigh-bors. These systems represent a considerable capital expense, typically several million dollars, to refineries and petrochemical plants. The cost associated with fence design, construction and installation typically rep-resents about 30-50% of the total system cost.Select a $20MM system to calculate the economic im-pact associated with implementation of ECC for the above benefit.Fence Height ReductionRecommendation
