Bayer Process Heat Exchangers Cleaning Efficiency: Optimizing the Acid Dissolution of Sodalite Scale

Aluminum metal is produced by the electrolytic reduction of aluminum oxide (Al2O3), mainly extracted from bauxite ore digested in a hot caustic soda solution. This solution is supersaturated with respect to sodium aluminate and silicate, which react together to form sodalite (3[Na2O⋅Al2O3⋅2SiO2⋅2H2O]⋅Na2CO3) at high temperatures. Heat exchanger tubes are scaled with this compound, which serious...

مازاد سرمایه در زمان ورشکستگی در مدل ریسک کلاسیک با عامل اغتشاش on the surplus prior to ruin in the perturbed classical risk process

هدف این تحقیق در نظر گرفتن مدل ریسک کلاسیک که با عامل فرآیند وینر ، به مدل ریسک کلاسیک با عامل اغتشاش تبدیل می شود. در این تحقیق فرمول هایی صریح برای تابع چگالی احتمال توام و حاشیه ای مقدار مازاد سرمایه بلافاصله قبل و در زمان ورشکستگی و همچنین تابع چگالی احتمالی برای مقادیر و اندازه خسارت هایی که باعث ورشکستگی شده اند، بررسی می شود. نیاز برای چنین تحقیقی بدین سبب احساس می شود که در مدل ریسک کل...
