Modelling and optimization of metals (As, Ca, Cd, Cr, Cu, Fe, Mg, and Pb) and Ethylene glycol butyl ether in paints using response surface method

Response surface methodology (RSM) and principal component analyses (PCA) modelling tools have been used in this study to quantitatively describe the interaction effects of more than one factor on system response for the modelling and optimization of experimental data. In Nigeria, there are no stringent policies in place by the government on paint production and this has led to unregulated paint products by producers in the commercial markets. Water-based paints currently available in Nigerian market were sampled. Experimental data of Metals (As, Ca, Cd, Cr, Cu, Fe, Mg, and Pb) and Ethylene glycol butyl ether (Volatile organic compounds (VOC)) measured using Inductively Coupled Plasma-Optical Emission Spectrometer (ICP-OES) and Gas Chromatography-Flame Ionisation Detector (GC-FID), respectively was used to develop a mathematical model. The principal component analyses were explained with a cumulative variance of 82% for the VOC and 76% for metals based on manufacturers. Estimated responses were compared with the experimentally determined responses and prediction capabilities of Response Surface Methodology. In the RSM, the 2 developed model had R value of 0.9569, with optimized value at 0.10 % (1000ppm) of Ethylene glycol butyl ether and concentration (ppm) ranges of As (383.0-1,930.0), Ca (614.0-10,400.0), Cd (98.0-2,000.0), Cr (10.3- 225.0), Cu (133.0-1,840.0), Fe 742.0-2,910.0, Mg (4,000.0-99,510.0), Pb (170.0-3,230.0). The correlation and optimization study employed are applicable for assessing the impact of hazardous air pollutants on indoor air quality and a good applicability in paint industries to produce products within the set limit of international standards. For the purpose of reducing sick building syndrome and protecting public health, it was important to investigate paints and sealers extensively.

The corundum-mullite was toughened by in-situ synthesized mullite whiskers and the process parameters influencing the fracture toughness of corundum-mullite, such as sintering temperature, addition amount of AlF3 and V2O5, were optimized by means of response surface method. Corundum-mullite with fracture toughness of 9.44 MPa.m-1/2 could be obtained under the optimized conditions, i.e. sintering temperature of 1400°C, 4.8 wt.% of AlF3 and 5.8 wt.% of V2O5. The results showed that it was feasible to prepare corundum-mullite toughened by in-situ synthesized mullite whiskers by the optimized parameters. In addition, an accurate model based on response surface method was proposed to predict the experimental results.

Fractionation Unit

Response Surface Method involving central composite design is employed to determine the optimal configuration of nine factors for maximizing the profit of a Condensate Fractionation Unit. When compared with the results from the base case and Taguchi method, the result from RSM shows higher profits by 33.1% and 1.16%, respectively. A further benefit of 0.64% is noticed when three insignificant factors were removed from the nine-factor experiment due to interactions between factors.

Abstrak Zirconia (ZrO2) merupakan material keramik yang banyak digunakan di industri. Pasir zirkon (ZrSiO4) merupakan salah satu sumber zirkonia. Produksi zirkonia dari pasir zirkon dapat dilakukan dengan proses perlakuan panas atau perlakuan kimia dengan tujuan memecah ikatan antara ZrO2 dan SiO2. Pada penelitian ini Response Surface Methodology (RSM) diaplikasikan untuk menentukan nilai optimal persentase ZrO2 dari proses dekomposisi pasir zirkon melalui proses perlakuan panas. Sampel yang disiapkan sebanyak 13 variasi dengan 3 replikasi. Analisis hasil percobaan didapatkan Eigen value dengan nilai –0,146262 (X1) dan 0,172908 (X2). Hal ini menunjukkan bahwa kombinasi temperatur dan waktu penahanan tidak teridentifikasi optimum pada satu titik saja namun tersebar di seluruh daerah saddle point.

Surface Method

Instead of using the conventional oxidation theory to depict a disk’s wear rate as a function of contact temperature, the response surface method (RSM) is herein introduced to relieve the one-factor-at-a-time defect in portraying tribological characteristics. By means of a central composite design technique, fewer operating conditions are needed to establish expressions for the wear rate parameter, the contact temperature and the friction coefficient as a function of sliding speed and applied load. A second degree polynomial was used to represent a curved surface which fits the experimental data. In addition to results for the designated operating conditions, wear rate parameters and contact temperatures obtained from the polynomials were compared with the experimental results. The activation energy in the wear rate expression can be derived from a function of sliding speed, applied load, and contact temperature. The experimental data for the wear rate parameter can be described by smooth curves, instead of two different straight lines in two temperature divisions.
