Abstract The application of biodiesel will increase in accordance with the government’s mandatory program for saving fossil fuels. challenging would come from particulate levels and water content. One efforts to fix issues is by adding rhodinol citronella oil as an additive. This research was conducted design a vacuum distillation process which has 500L capacity determine fractionation unit. Si...

CPC solar collectors are a combination of new technologies that make it possible to generate heat from radiant energy by transferring between the absorber and fluid. This study was performed based on transfer equations proposing mathematical model, as reported in literature. A compound parabolic concentrators collector (CPC) numerical model simulated coded Aspen HYSYS MATLAB software validated ...

Anisole is a straw-colored aromatic compound mainly used in making solvents, flavoring agents, perfumes, fuel additives, and the synthesis industries. Anisole, also known as methoxybenzene, synthesized from sodium phenoxide or phenol using various methylating agents. The use of dimethyl ether (DME) an alkylating agent seldom reported literature. Herein, we have anisole through O-alkylation proc...

Distillation columns are complex processes for modeling and controlling. These columns are significant parts of most chemical industries for separation of components. Control of this process is essential for achieving certain purity for products with a minimum cost. However, nonlinearities, multivariable interaction, non-stationary behavior and severity of disturbances inside the column made th...

This work's first aim is to fit the simulated results pilot plant data from Test Centre Mongstad (TCM) for both high and low CO2 exhaust gas inlet concentrations. The next evaluate whether fitted parameters one scenario (a set of experimental under specified conditions) give reasonable predictions other conditions. scenarios at TCM have been in a rate-based model Aspen Plus (RateSep) an equilib...

The prediction of phase equilibria for hydrocarbon/water blends in separators, is a subject considerable importance chemical processes. Despite its relevance, there are still pending questions. Among them, the correct number phases. While stability analysis using Gibbs Free Energy mixing and NRTL model, provide good understanding with calculation issues, when HYSYS V9 Aspen Plus software, this ...
