Thermodynamic Analysis of Raw Mill in Cement Industry Using Aspen Plus Simulator

Thermodynamic Study of Hot Potassium Carbonate Solution Using Aspen Plus

This paper presents a study on the thermodynamics and transport properties of hot potassium carbonate aqueous system (HPC) using electrolyte non-random two liquid, (ELECNRTL) model. The operation conditions are varied to determine the system liquid phase stability range at the standard and critical conditions. A case study involving 30 wt% K2CO3, H2O standard system at pressure of 1 bar and tem...

Analysis of Credit-Strength of Cement Industry in Bangladesh

In this study it has been initiated to find out the credit strength and financial performance of cement industries in Bangladesh through investigating the financial report for the period from 2007 to 2011. Financial ratios are employed to measure the Liquidity (Working capital to Total Assets), Profitability (Retained Earnings to Total Assets), Efficiency (Earnings before Interest and Taxes to ...

Two Phase Modeling of Char Combustion in a Circulating Fluidized Bed Reactor Using ASPEN PLUS

In this paper, combustion of char in the riser of circulating fluidized bed was modeled using ASPEN PLUS. Since physical and chemical phenomena are involved in the process, the model integrates the two-phase hydrodynamic sub-model with the reaction sub-model derived from the literature. In the proposed model, the fluidized bed is divided into several sections and the behavior of each section wa...

Simulation of Biomass Gasification in Fluidized Bed Using Aspen Plus

Gasification is a thermo-chemical process to convert carbon-based compounds such as biomass and coal into a gaseous fuel. Among the various types of gasification methods, fluidized bed gasification is one which is considered as more efficient method than others as biomass is fluidized in a mixture of air/oxygen and steam. In the present study, a comprehensive steady state process model has been...
