Thermodynamic models for CO2 - H2O -alkanolamine systems, a discussion

a study on thermodynamic models for simulation of 1,3 butadiene purification columns

attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...

Thermodynamic analysis of methane reforming with CO2, CO2+H2O and CO2+O2 for hydrogen and synthesis gas production

Dry reforming of methane for the production of hydrogen and syngas has attracted much attention from both industrial and environmental aspects. The major problem encountered in the application of this process is the rapid deactivation of the catalyst, which is mainly due to coke accumulation and sintering of the catalyst. As an alternative to reduce the coke formation, the combination of CO2 re...

Thermodynamic behavior of FeCl3-H2O and HCl-FeCl3-H2O systems - A Pitzer Model at 25°C

Most of the speciation models of aqueous electrolyte systems are based on the “ion pairing and complexing approach”. They are only suitable for aqueous solutions with ionic strengths lower than about 1 eq.kgw . For highly saline solutions, an approach based on “specific-ion interactions” (the so-called “Pitzer approach”) provides much more accurate results. Various thermodynamic databases suppo...

a new approach to credibility premium for zero-inflated poisson models for panel data

هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...
