“…The obtained "Predicted R-square value" value of 0.8768 was also coincided with the "Adjusted R-squared value" (0.9731). The predicted R 2 was within 0.2 difference compared to the adjusted R 2 [48]. The "Adeq Precision" of 24.242, which measured the signal to noise ratio, was also much greater than the desirable value (4), indicating an adequate precision.…”

“…In addition to needing little experimental data, it considers interactions between explanatory variables. Recently, this method has been applied to model different chemical engineering processes (Tabandeh et al, [10] Hosseinpour et al [11] ). Statistical analysis was done using the statistical package Design-Expert, version 9.0.5.…”

This study employs the response surface method in conjunction with a user-defined design to model the solubility of carbon dioxide in different bitumen cuts. Two different sets of data for carbon dioxide solubility in Cold Lake bitumen were considered. Temperature, pressure, and the bitumen cuts' molecular mass were selected as the explanatory variables. Scatter plots were used to determine the appropriate transformations for the explanatory variables. An ANOVA test was considered in a step-wise manner to select the significant parameters. A second-order dependency on temperature and a first-order dependency on the pressure and molecular mass were observed. In addition, a binary interaction between the molecular mass and pressure was observed. The developed correlation modelled carbon dioxide solubility in bitumen cuts with an AARD of 5 % for all the experimental data. The perturbation curve emphasized the strong dependency of solubility on temperature and pressure.

“…Response surface methodology (RSM), a useful method to clarify how several factors influenced the responses, was one of the most typical designs of experiment . Among them, central composite design was the most commonly used second‐order design . As a proof, attempts were made to optimize both the encapsulation efficiency and the release characteristics of microcapsules prepared using coordination assembly.…”

A model chlorpyrifos microcapsule was prepared using coordination assembly between Fe 31 and tannic acid (TA). The influence of independent variables such as the dropping rate of TA (X 1 ) and Fe 31 (X 3 ), the concentration of TA (X 2 ) and Fe 31 (X 4 ), and the reaction temperature (X 5 ) on the encapsulation efficiency (R 1 ) and release characteristics (R 2 ) of the microcapsule had been investigated, based on a central composite design with five factors and five levels. The results showed that the main factors influencing R 1 and R 2 were X 4 and X 2 , then the interaction between X 2 and X 4 , followed by X 5 and X 3 . The optimal formula mainly based on higher R 1 and lower R 2 were determined and then tested. The optimized conditions led to an encapsulation efficiency and cumulative release proportion of 97.12% 6 0.72% and 40.07% 6 0.53%, along with the average relative errors of predicted values being 1.78% and 21.60%, respectively.
