Stability Study on Ethylene Oxide Industrial Reaction from the Management of Critical Process Variables

Abstract

The performance of an ethylene oxide process is measured by the selectivity reaction. A production unit was studied in order to maximize selectivity by developing a strategy to manage key process variables. A statistical analysis of data indicated that four variables account for the influence over selectivity. Regression models were developed in order to represent the process selectivity as a function of these variables. The model proposed was statistically and phenomenologically validated, demonstrating consistency with the current data process. The model was deployed in subsets, representing possible operational conditions. Surface responses were evaluated for each model deployed and provided to identify the optimum operational conditions.

Optimization of Epoxidized Methyl Acetoricinoleate Synthesis by Response Surface Methodology

“…d), it was observed that the epoxy value increased slightly with increasing temperature from 50 to 90 °C; a maximum value of 5.01 % was observed at 90 °C, and the value decreased thereafter. According to reports in the literature, too high a reaction temperature leads to oxirane cleavage of EMAR . The theoretical epoxy value of EMAR was 6.65 %, according to material balance in current experiment.…”
