Industrial flare performance at low flow conditions. 2. / Vincent M. Torres in Industrial & engineering chemistry research, Vol. 51 N° 39 (Octobre 2012)

Torres, Auteur ; Scott Herndon, Auteur ; David T. Allen, Auteur Année de publication : 2012 Article en page(s) : pp. 12569–12576 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Industrial flare Steam Résumé : Full-scale tests of steam- and air-assisted industrial flares were conducted using low BTU content (lower heating value) vent gases at low flow rates. A 36″ diameter steam-assisted flare with a flow capacity of 937,000 lb/h and a 24″ diameter air-assisted flare with a flow capacity of 144,000 pounds per hour were operated with mixtures of natural gas, propylene, and nitrogen or natural gas, propane, and nitrogen at flow rates less than 1% of maximum flow. Combustion efficiency (percentage of the flared gases converted to carbon dioxide and water) ranged from less than 50% to more than 99%. For the steam-assisted flare, combustion efficiency (CE) at low steam-to-vent gas flow ratios (0.5–1.0) was typically in excess of 95%. CE would gradually decrease as steam-to-vent gas ratio increased, to a point, after which CE would decrease dramatically. The steam-to-vent gas ratio at which CE would decrease dramatically depended on the heating value of the vent gas and the position of the steam injection. Higher heating values of the vent gas (600 vs 350 BTU/scf) and the minimization of steam coinjected with the vent gas, rather than injected at the flare tip, promoted higher CE. For the air-assisted flare, CE at low air assist rates ( ISSN : 0888-5885 En ligne : http://pubs.acs.org/doi/abs/10.1021/ie202675f [article] Industrial flare performance at low flow conditions. 2. : Steam- and air-assisted flares [texte imprimé] / Vincent M.

Temporal variability in flaring emissions in the houston–galveston area / Radovan T. Pavlovic in Industrial & engineering chemistry research, Vol. 51 N° 39 (Octobre 2012)  

Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 51 N° 39 (Octobre 2012) . - pp. 12653–12662 Titre : Temporal variability in flaring emissions in the houston–galveston area Type de document : texte imprimé Auteurs : Radovan T. Pavlovic, Auteur ; David T. Allen, Auteur ; Elena C. McDonald-Buller, Auteur Année de publication : 2012 Article en page(s) : pp. 12653–12662 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Industrial air pollutant emission Résumé : Recent studies performed in the Houston–Galveston–Brazoria (HGB) area indicate that some industrial air pollutant emission sources exhibit high temporal variability that can lead to very rapid ozone formation, especially when emissions include highly reactive volatile organic compounds. This motivated the collection of a unique data set of air pollutant emissions, from industrial facilities, reported with an hourly time resolution. The industrial flares portion of this data set was utilized in this work to characterize and model the highly variable temporal patterns of flare emissions at petrochemical facilities. Petrochemical and chemical manufacturing flares were grouped into categories based on industrial process they service, chemical composition of the flared gas, and the temporal patterns of their emissions. Stochastic models were developed for each categorization of flare emissions and provide representative temporal profiles for flares in specific types of operations in the petrochemical and chemical manufacturing sectors.
