چکیده
Consequence modeling involves the determination of the impacts of process accidents involving hazardous materials on people, the environment and the process. The amount and form of hazardous material released is determined for toxic materials, flammables, and explosives (called the source term). The dispersion of the released material through and beyond the facility is studied. The distance traveled and area covered are determined. For toxic materials, their effects on people and the environment are evaluated. For flammables, the impact of the heat radiation from a fire on people and equipment is calculated. For explosive materials, the impact of blast overpressures on people, equipment and structures are calculated. Models tailored to each particular situation are used to evaluate consequences. Gas, two phase, and liquid releases are modeled and their discharge rates are calculated .Dispersion is modeled for buoyant or heavy gases, as appropriate, taking account of the range of atmospheric conditions possible at the time of release. Toxicity data and dose-response models are used to model toxic effects. Various types of fires are modeled including pool, jet, flash, fireball, and warehouse fires. Types of explosions modeled include confined, unconfined, and dust explosions as well as BLEVEs )Boiling Liquid Expanding Vapor Explosion), thermal decompositions, and runaway reactions. At this study we are resolution to Modeling and evaluation of Gas dispersion, Jet fire and Explosion of propane treatment and dying unit (114) from South Pars Gas Field Development Phases 15&16 Onshore Facilities project using PHAST software and we will denote the prohibited access and beamed structure area for this unit.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
