The Cost

A techno-economic analysis was performed for a 100 dry-ton/day (90,719 kg/day) fast pyrolysis transportable plant. Renewable Oil International® LLC provided the life cycle cost of operating a 100 dry-ton/day fast pyrolysis system using southern pine wood chips as feedstock. Since data was not available from an actual large-scale plant, the study examined data obtained from an actual 15 dry-ton/day pilot plant and from several smaller plants. These data were used to obtain base figures to aid in the development of models to generate scaled-up costs for a larger 100 dry-ton/day facility. Bio-oil represented 60% of mass of product yield. The cost for the bio-oil from fast pyrolysis was valued at $0.94/gal. Energy cost bio-oil and char was valued at $6.35/MMBTU. Costs associated with purchasing feedstocks can drastically influence the final cost of the bio-oil. The assumed cost of feedstocks was $25/wet ton or $50/dry ton. This paper is part of a larger study investigating the economic and environmental impacts for producing bio-oil / biocide wood preservatives.

Sweet Proteins

There are currently worldwide efforts to reduce sugar intake due to the various adverse health effects linked with the overconsumption of sugars. Artificial sweeteners have been used as an alternative to nutritive sugars in numerous applications; however, their long-term effects on human health remain controversial. This led to a shift in consumer preference towards non-caloric sweeteners from natural sources. Thaumatins are a class of intensely sweet proteins found in arils of the fruits of the West-African plant Thaumatococcus daniellii. Thaumatins’ current production method through aqueous extraction from this plant and uncertainty of the harvest from tropical rainforests limits its supply while the demand is increasing. Despite successful recombinant expression of the protein in several organisms, no large-scale bioproduction facilities exist. We present preliminary process design, process simulation, and economic analysis for a large-scale (50 metric tons/year) production of a thaumatin II variant using several different molecular farming platforms.

Offshore Oil

In this paper, a new Lagrange relaxation based decomposition algorithm for the integrated offshore oil production planning optimization is presented. In our previous study (Gao et al. Computers and Chemical Engineering, 2020, 133, 106674), a multiperiod mixed-integer nonlinear programming (MINLP) model considering both well operation and flow assurance simultaneously had been proposed. However, due to the large-scale nature of the problem, i.e., too many oil wells and long planning time cycle, the optimization problem makes it difficult to get a satisfactory solution in a reasonable time. As an effective method, Lagrange relaxation based decomposition algorithms can provide more compact bounds and thus result in a smaller duality gap. Specifically, Lagrange multiplier is introduced to relax coupling constraints of multi-batch units and thus some moderate scale sub-problems result. Moreover, dual problem is constructed for iteration. As a result, the original integrated large-scale model is decomposed into several single-batch subproblems and solved simultaneously by commercial solvers. Computational results show that the proposed method can reduce the solving time up to 43% or even more. Meanwhile, the planning results are close to those obtained by the original model. Moreover, the larger the problem size, the better the proposed LR algorithm is than the original model.

Aim. As part of a large-scale business transformation, Gazprom Neft is implementing new approaches to improving economic efficiency. One of such approaches is the launch of the “Renovation” project program, the purpose of which is to achieve maximum profitability of the basic well stock. The article describes the results of the study and formation of a set of measures to improve the economic efficiency of oil production at the fields of Gazpromneft-Khantos. Materials and methods. The key feature of “Renovation” is that the goal setting and the formation of key performance indicators of project teams are made not from the previously achieved result, but from the potential. To do this, a detailed technical and economic analysis of the factors affecting the profitability of oil production is first carried out, and the potential for increasing profitability is determined. After that, hypotheses are worked out to increase the economic efficiency of production and a set of measures is formed to realize the identified potential. The cross-functional teams of the “Renovation” program projects are formed around the core-team that includes specialists in geology, development, production, engineering, energy management, economics and IT. This allows teams to solve non-standard tasks in a short time, in a complex way, without attracting external leverage, which is an absolute competitive advantage. Results. The program of optimization measures developed by the cross-functional team of the Renovation project will provide the potential for the growth of the profitability of Gazpromneft-Khantos in the period from 2021 to 2030. Conclusions. The article presents the developed and implemented cases on reducing operating costs in various areas — geology and reservoir engineering, energy efficiency, oil production technologies, downhole operations and hydraulic fracturing, oilfield chemistry.

Corncob is usually disposed of directly as waste, creating problems in the environment, while it can be converted into valuable materials. This research aimed to evaluate the literature review on briquette production from agricultural waste (using non-binder and cold press with a binder) and the current works on techno-economic analysis, to propose an optimal design for the production of briquette from corncob waste, and to perform a techno-economic analysis based on the selected optimal processing method. The engineering perspective based on stoichiometry and mass balance showed the potential corncob briquette manufacture in both home and large scales due to the possible use of inexpensive and commercially available equipment and raw materials. The economic perspective [based on several economic evaluation factors (i.e., gross profit margin, payback period, break-even point, cumulative net present value, return of investment, internal rate return, and profitability index) under ideal and non-ideal conditions by considering internal (i.e., sales, raw materials, utilities, and variable cost) and external aspects (i.e., tax)] confirmed the prospective development of the project in the large-scale production with a lifetime of more than 18 years. The main issue in the project is the raw material (i.e. tapioca flour), giving the most impact on the project’s feasibility. Even in severe conditions, the project is feasible. The great endurance was also confirmed in the case of a higher tax rate. This study demonstrates the importance of producing corncob-based briquettes for improving the economic value and giving alternatives for problem solvers in the utilization of agricultural waste.

Space expansionism, science fiction, and space developments are intimately linked. SF from Verne, Wells, and others inspires space expansionists, and SF is shaped by space discoveries. SF makes space expansionism seem plausible but is often unbound by scientific possibility. An assessment of building block, life-engineering, and transformative technologies reveals that large-scale space activities are becoming more feasible, but creating enclosed ecologies, geo-engineering and terraforming remain doubtful. Anticipating the consequences of new technologies (technology assessment) remains difficult. Technology governance is plagued by recalcitrant syndromes. Theorists of catastrophic and existential risk view space colonization as necessary to escape a long list of possible major calamities (including hostile artificial superintelligence and misused genetic engineering for improved humans, called transhumanism). Human survival increasingly depends on competent futurism and social capacities to steer technology with reversals, regulations, and relinquishments, but these are difficult to establish and maintain. Can vital arrangements of restraint survive large-scale space expansion?
