This study reports the multicomponent adsorption of dye AB25, nickel (Ni2+) and zinc (Zn2+) ions on an activated carbon using binary mixtures of metal and dye, and packed bed columns at different operating conditions. Design parameters of packed bed adsorption columns have been calculated using the breakthrough curves and Thomas model, and an analysis has been performed to determine the effect and magnitude of the synergistic adsorption on the design parameters and adsorbent performance. Results showed that there is a strong synergistic adsorption of heavy metals on activated carbon caused by the presence of dye AB25 in binary mixtures. The …

This study introduces the application of nature-inspired metaheuristic algorithms for performing critical point calculations in multicomponent reservoir fluids. These algorithms are Monkey - Krill Herd Hybrid (MAKHA), Intelligent Firefly Algorithm (IFA), Covariance Matrix Adaptation Evolution Strategy (CMAES), Artificial Bee Colony (ABC), Cuckoo Search (CS), Bare Bones Particle Swarm Optimization (BBPSO) and Flower Pollination Algorithm (FPA). Capabilities and limitations of these optimizers have been analyzed using black oil, volatile and condensate reservoir fluids with fifty components. Results showed that BBPSO, IFA and FPA outperformed other nature-inspired methods for critical point calculations in tested fluids. In particular, BBPSO offered the best efficiency-reliability …
