The discharge of oil and grease (O&G) containing effluent without treatment may contaminate the aquatic environs freshwater. removal O&G from simulated refinery desalter (SRDE) by activated carbon (AC) originated chemical activation/carbonization corn cobs (CCs) was investigated through fixed-bed column studies. (CCAC) characterized to determine its physicochemical properties, functional groups presently active on it partaking in adsorption process. CCAC size (150, 300 600 µm), initial...

This work focuses on the characterization and performance of adsorptive membrane produced (via blending) functionalized waste polyethylene water sachets bags (PESWAB) with biopolymers. An (5.0 µm pore size) (2.0 mm thickness) was fabricated from 9.0 g wt composite PESWAB, chitosan, cellulose acetate in corresponding ratios 1:2:1. Zeta potential, FTIR, SEM/EDX, contact angle, TGA/DTA were used to characterize membrane. Response surface methodology (RSM) model effects process variables uptake...

Abstract In this research work, melon oil was used as feedstock for methyl ester production. The aimed at optimizing the reaction conditions yield from oil. Response surface methodology (RSM), based on a five level, four variable central composite designs (CCD)was to optimize and statistically analyze interaction effect of process parameter during biodiesel production processes. A total 30 experiments were conducted study methanol molar ratio, catalyst weight, temperature time. optimal found...

Temperature relationships of Vigna subteranea flower (VSFE) extract on the corrosion carbon steel in 2.0 M H2SO4 at 303-323 ˚K was studied by weight loss method. The obtained results show that VSFE acts as inhibitor for solution. inhibition efficiency found to increase with concentration but decreased acid and temperature, which is suggestive physical adsorption mechanism although chemisorption may play a part. onto surface follow Langmuir isotherm. correlation coefficient (R²) ranging from...

This study investigated oil extraction from rice bran a by-product of gotten different sources (Afikpo, Abakaliki, and Emene). The was extracted particle sizes (150 µm, 300 420 µm) the using three solvents namely chloroform, petroleum ether, n-hexane at constant time 120 minutes via soxhlet extractor. physiochemical properties were boiling point, saponification values refractive index 77 <sup>o</sup>C, 185.130, 1.334, respectively. Also acid value, surface tension, iodine...
