Investigation of various process parameters on the solubility of carbon dioxide in phosphonium-based deep eutectic solvents and their aqueous mixtures: Experimental and modeling

Parametric gasification process of sugarcane bagasse for syngas production

“…In fact, the adequate precision provides another way to evaluate the adequacy of a model for predictive purposes. The desirable ratio of aadequate precision is >4 which indicate adequate model discrimination[51]. According to the values listed in theTable 4, all developed models have adequate precision values >7 confirming their desirable amount.Furthermore, the coefficient of variance (C.V.%) is another term that is the ratio of estimated standard error to the mean value of the response.…”

“…Generally, aforementioned plots are used in order to confirm the residual analysis of the RSM-CCD and to certify the analysis data fit with the aid of statistical assumptions. To be specific, normal probability plot helps to determine whether the experimental results follow a normal distribution [51].…”

“…Additionally, the plots (i.e., externally standardized residuals) considered for representing residuals vs. experimental data and residuals vs. predicted are capable and accessible approaches in order to identify the outlier results for each actual data and predicted values, respectively [51,66].…”

“…According to the values listed in theTable 4, all developed models have adequate precision values >7 confirming their desirable amount.Furthermore, the coefficient of variance (C.V.%) is another term that is the ratio of estimated standard error to the mean value of the response. In fact, C.V. < 10% indicates the high accuracy, reproducibility and dependability of the experiments[50][51][52]. According to the C.V. values presented inTable 4, all models possess a C.V. < 9.0% showing the great precision, reliability and dependability of the experimental data acquired and associated models for four above-mentioned responses.…”

A comparative study of dynamic adsorption of anionic synthetic and nanocellulose-based surfactant in Malaysian reservoir

“…One of the remarkable characteristic of nanocellulosebased surfactant is that it can easily pass through typical pore throats in reservoirs. Nanocellulose-based surfactant, which can be extracted from OPEFB, is also a biodegradable material (bio-nano) and low-cost alternative compared with current chemical surfactant (Han et al 2009;Ghaedi et al 2017;Karnanda et al 2013). This is expensive and may contaminate the environment if left under reservoir.…”
