A review of response surface methodology for biogas process optimization

Optimization of Ultrasound-Assisted Extraction of Free Phenolic Compounds and In Vitro Biological Activity from Peach Fruit Using Response Surface Methodology

“…RMS is a collection of statistical and mathematical techniques useful for developing, improving, and optimizing processes [22]. RMS is preferred because it minimizes the number of experiments for a specific number of factors and their levels [23]. In general, RMS has two main types of designs-the Box-Behnken design (BBD) and the centralcomposite design (CCD).…”

Optimization and Analysis of a Low-Pressure Water Scrubbing Biogas Upgrading System via the Taguchi and Response Surface Methodology Approaches

“…Besides, a previous study (Song et al, 2014) used a novel cryogenic CO2 capture process based on three levels of the Central Composite Design (CCD) to obtain the desired optimum conditions. The CCD happens to be the most popular design method in RSM (Djimtoingar et al, 2022). Previous efforts to capture the application of the CCD for biogas upgrading were undertaken by (Morero et al, 2017) through a simulation study with three varied absorber-stripper configurations consisting of solvents like water, dimethyl ethers of polyethylene glycol and diglycolamine.…”

“…ANOVA analysis was also carried out to test the developed quadratic model validity. From the estimated models, response surfaces were developed using Design-Expert 13 (Stat-Ease Inc., Minneapolis, USA) which is the most widely used softwares (Djimtoingar et al, 2022).…”

“…Biogas is comprised of constituent gases namely methane (CH4) (55-70%), carbon dioxide (CO2) (30-40%), hydrogen sulfide (H2S) (0-20,000ppm), nitrogen (N2) (0-2%), ammonia (NH4) (0.05%), water vapor (H2O) (0-7%) and other trace elements (Awe et al, 2017;Singhal et al, 2017). The raw biogas composition largely depends on the pH, temperature, retention time, pretreatment of the substrate and the loading rate (Djimtoingar et al, 2022). The methane component in biogas is the only combustible gas, while the presence of carbon dioxide reduces the calorific value of the gas.…”

An experimental and response-surface-based optimization approach towards production of producer gas in a circulating fluidized bed gasifier using blends of renewable fibre-based biomass mixtures

“…9 In order to predict the interactions among the variables, RSM has the distinct benefit of identifying optimal conditions with maximum data and minimal trails. 10,11 After the extensive literature review cited above, it has been found that very few publications are reported in the literature related towards optimization (response surface methodology) of biomass-based producer gas production. Literature studies have reported application of RSM methodology in gasification employing low-grade coal 12 downdraft gasifier, 13 spent pot lining waste materials, 14 and eucalyptus wood sawdust.…”
