the scheduling problems are the non-polynomial problems-hard (np-hard), is to solve it, and meta-heuristic innovative method compared with the exact method require less time and memory.in this research, developed imperialistic competitive algorithm used to solving the single-mode resource-constrained project scheduling problem.also the basic feasible solution algorithm used in order to increase...

Abstract Artificial intelligence (AI) is gaining acceptance for modern control systems in various applications daily life including the Chemical process industry. Above all, application of AI increasing field membrane-based treatment where it shows great potential until now. Membrane separations are generally recognized as energy-efficient processes. In particular, membrane desalination, forwar...

The United Arab Emirates (UAE) is making significant progress in improving its economy by attracting tourists and trade. In the short run, however, economic activity will continue to be more based on oil, natural gas, related industries. Rising demand for gas power plants industrial users, such as petrochemicals steelmakers, has made UAE a net importer, prompting country launch multibillion-dol...

Abstract Esters are widely used in plastics, textile fibers, and general petrochemicals. Usually, esters produced via chemical synthesis or enzymatic processes from the corresponding alcohols acids. However, fermentative production of and/or acids has recently also become feasible. Here we report a cognate microbial consortium capable producing butyl butyrate. This consists two engineered butyr...

The concept of biorefinery constitutes a significant contributing factor to the emerging transition toward sustainable bioeconomy. In such context, replacing oil and petrochemicals by biomass may involve several feedstocks, platforms, processes, technologies, as well final products. This paper concentrates on complex process transferring from laboratory industry, sheds light techno-economic com...

ZSM-5 is an important class of acid catalyst for producing bio-oil rich in petrochemicals; however, continuous efforts are required to improve the conversion efficiency biomass-derived oxygenates with large molecular sizes. The mesoporous (N-ZSM-5) was prepared a post-treatment method nanocellulose as green template this study induce additional surface and porous features. promoted properties N...
