This work presents a detailed review and comparative analysis of the process design and economics of n-butanol production using corn grain and corn stover. This includes reviewing the most recent n-butanol technologies; demonstrating the impact of key parameters (e.g. plant capacity, raw material pricing, yield) on the overall n-butanol process economics; and comparing how cellulosic biomass conversion technologies and challenges differ from traditional sugar-based n-butanol conversion technology. A major challenge of n-butanol production is the low n-butanol yield (compared to ethanol), resulting in higher production costs. However, recent research efforts have achieved signifi cant yield improvements using a combination of genetic engineering, fermentation techniques, and integrated process development using continuous fermentation with online stripping to remove n-butanol during fermentation. This study presents the advances in n-butanol research for both sugar-based (corn) and cellulosic (corn stover) feedstocks, and also provides a comparison of overall process technologies and process economics. In addition, the results of a sensitivity analysis comparing various technologies, sugar yields, and coproduct distributions are discussed in order to provide research guidance.

Ecological engineering education: ways of formation and development

A system approach based on ecological and economic development required organizing the specialists training in the field of industrial ecology which was first established in our country in the 70s of the last century. In Polzunov Altai State Technical University (AltSTU) at the Department of Chemical Engineering and Engineering Ecology the training of environmental engineers began in the following areas: protection of the atmosphere, hydrosphere and lithosphere from industrial pollution with a specialization in wasted gases purification, wastewater treatment and solid waste recycling. Along with the educational process the scientific direction of creating energy efficient and resource-saving low-waste technologies and natural and waste water treatment was organized. In this area a large number of PhD and doctoral works based on innovative technologies in the field of separation of liquid industrial mixtures - wastes of various industries, as well as water treatment and water purification processes, were performed. More than 1000 environmental engineers have been trained since the creation of the program. Most of them stayed to work in Altai Krai. The accumulated experience made it possible to create a system of advanced training for engineering personnel in the field of environmental protection and ecological security and to win the Russian presidential grants including overseas internships in Sweden and Finland. This allowed to get acquainted with the concept of the best available technologies in the field of environmental protection for sustainable development.

The determination of hydraulic resistance during laminar filtration through layers of sorbents and ion-exchange granules in environmental mass exchange equipment

et al. 2020

View full text Add to dashboard Cite

The paper presents main calculation dependencies, their advantages and disadvantages for calculating the hydraulic resistance of granular and porous layers in the area of low filtration rates. Approaches are given to account for the influence of porosity and size of particles (sorbent granules) that differ in the values of constants and different ways to account for the influence of particle shape on the hydraulic resistance of the granular layer.
