Reactive distillation processes couple chemical reactions and physical separations into a single unit operation. The ethyl acetate production by esterification reaction is equilibrium limited and is suitable to be carried out in a distillation column. In the present work, a reactive distillation column for the production of ethyl acetate is simulated using Aspen Plus. The component compositions...

In the light of increasing fears about climate change, greenhouse gas mitigation technologies have assumed growing importance. In the United States, energy related CO2 emissions accounted for 98% of the total emissions in 2007 with electricity generation accounting for 40% of the total. Carbon capture and sequestration (CCS) is one of the options that can enable the utilization of fossil fuels ...

There is concern over the decline of aspen and the lack of successful regeneration due to excessive browsing of aspen suckers by cattle and other wild and domestic ungulates. We conducted a 2-yr study on Lassen National Forest, California, to aid development of cattle grazing strategies to enhance aspen regeneration. We evaluated seasonal biomass, nutritional quality, and utilization by cattle ...

This paper presents a simplified process simulation model of typical waste polyethylene gasification in a fluidized bed reactor using Aspen Plus. The proposed model incorporates both physical and chemical processes, including drying, pyrolysis, combustion and gasification, by using various inbuilt modules to predict the resulting product gas composition and temperature. A detailed sensitivity a...

This research aims at developing anoperator training simulator (OTS) using AspenOTS Frameworkfor fatty acid methyl ester (FAME) production plant. All over the world, there is an increasing interest towards the use of vegetable oils in much desired ecofriendly biodiesel production. In view of environmental concerns due to high polluting nature of fossil fuels and also because of the limited avai...

In order to solve the problem of complex calculation logistics value in process simulation, based on parameter characteristics ASPEN PLUS, a simplified model is proposed. The comparison with exercom shows that error results this paper less than 1%, which verifies correctness model. flow provides convenience for simulation software PLUS analyze process. Based and ?fuel cost? thermal economics, c...
