This work presents an optimized design of a methyl diethanolamine CO 2 capture unit for clean hydrogen production via steam methane reforming natural gas, where is captured from the pressurized water-gas shifted syngas. We propose modified version standard MDEA-based process flowsheet, and we optimize operating conditions by solving multi-objective optimization problem to minimize energy consum...

Acetaldehyde diethyl acetal (herein called acetal) is an important pollutant of anhydrous ethanol. Isobaric vapor–liquid equilibrium (VLE) ethanol–acetal binary system was measured using a vapor condensate and liquid circulation VLE still. The experimental data were correlated with Wilson, nonrandom two-liquid (NRTL), universal quasichemical (UNIQUAC) activity coefficient models, which found su...

Mathematical modelling methods were used at Wheal Jane. to investigate the sensitivity of the Stokes hydrosizer to changes in the operating variables, with the view to improving the process efficiency. The major conclusion was that the hydrosizer was overloaded. The results indicated that throughput and spigot densities were the most sensitive variables. The model predictions demonstrated that ...

The generation of end-of-life light-emitting diodes (LEDs) requires efforts to minimize waste and recycle critical raw elements (gallium, indium, rare earths). This review critically analyzes recycling processes such as physical, hydrometallurgical, pyrometallurgical treatments. An insight into gallium compounds (GaN, GaAs) their influence on strategies is provided. Pre-treatment plays a role i...

The steel industry is among the highest carbon-emitting industrial sectors. Since production process already exhaustively optimized, alternative routes are sought in order to increase carbon efficiency and reduce these emissions. During production, three main carbon-containing off-gases generated: blast furnace gas, coke oven gas basic oxygen gas. In present work, addition of renewable hydrogen...

Design is one of the most complex and creative tasks undertaken by chemical engineers. The early production stages of chemical design require an adequate support because of their critical impact on the competitiveness of the final products, as well as their environmental impact. In cooperation with researchers and industries from the chemical engineering domain, we have created an integrated fl...

A novel manufacturing strategy based on continuous processing integrated with online monitoring tools coupled with efficient automatic feedback control system is highly desired for efficient Quality by Design (QbD) based manufacturing of the next generation of pharmaceutical products with optimal consumption of time, space and resources. In this manuscript, an efficient plant-wide control strat...

Due to the environmental and price issues of current energy crisis, scientists and technologists around the globe are intensively searching for new environmentally less-impact form of clean energy that will reduce the high dependency on fossil fuel. Particularly hydrogen can be produced from biomass via thermochemical processes including pyrolysis and gasification due to the economic advantage ...

Process network problems can be formulated as Generalized Disjunctive Programs where a logicbased representation is used to deal with the discrete and continuous decisions. A new deterministic algorithm for the global optimization of process networks is presented in this work. The proposed algorithm, which does not rely on spatial branch-and-bound, is based on the LogicBased Outer Approximation...

Micro-fabricated fuel cell systems are a potential consumer product with the promise to outperform batteries for man-portable power generation in terms of the achievable energy density. A great variety of potential devices are being considered in various research institutions and thus there is a need for a systematic product design methodology, including comparison of alternatives and examinati...
