چکیده

Disulfide oil (DSO) is a by-product of refineries obtained by removing mercaptans from hydrocarbon compounds and has many adverse environmental effects. In this paper, we try to replace this base sulfide compound with the valuable DMDS, which is used in cracking furnaces for olefin production as a coke and CO inhibitor and evaluate the refining of this material to extract beneficial sulfide compounds such as DMDS in it. After extracting DMDS, it can be used directly in steam cracking of hydrocarbons. DEDS and MEDS are significant components of DSO and cannot reduce coke formation as much as DMDS due to their different decomposition temperature compared to DMDS. Also, each of them releases various free radicals after decomposition. Therefore, refining DSO and separating the DMDS from it, which is more valuable than other compounds, could make a suitable source of inhibitor for the olefin plants.

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.
