چکیده
Ozone layer destruction gases like halogenated hydrocarbons are used in some processes like solvent extraction, fire fighting, and as refrigerants in petrochemical industries. In this study, national acts and protocols in addition of international regulations, about ozone layer destruction gases were reviewed. According to protocols' constraints, the strategy of substitution of these gases by ozone friendly gases (with considering their potential of ozone layer destruction) was followed. For this purpose, application of destructive gases in a Petrochemical Complex as case study was assessed and estimated using mass balance method. According to results of this research, it is suggested that instead of Halon 1211, CO2 gas is used as extinguisher and R-22 is good substitute for R-12. Candidate substitutions were selected depend on those potential of ozone layer destruction and they were proposed to company to perform. Finally, substitution of gases was assessed and recommended to all of petrochemical industries in Iran.کلیدواژه ها

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.
