How Circular Innovation Is Learned: A Process Study of Modularity‐Based Initiatives in Industrial Firms

Business Strategy and the Environment, EarlyView.
ABSTRACT Circular innovation (CI) research has identified a wide range of circular strategies and design approaches, yet offers limited insight into how CI evolves as a learning process within firms and which governance mechanisms guide this progression. Drawing on organizational learning (OL), this study examines how exploration and exploitation shape

Improving The Performance Of Gas Turbine Power Plant By Modified Axial Turbine

, 2018
Computer-based optimization techniques can be employed to improve the efficiency of energy conversions processes, including reducing the aerodynamic loss in a thermal power plant turbomachine. In this paper, towards mitigating secondary flow losses, a design optimization workflow is implemented for the casing geometry of a 1.5 stage axial flow turbine ...

Scalable catalyst production process for oleate hydratase whole‐cell biocatalysis

Biotechnology Progress, EarlyView.
This study establishes a scalable lactose‐induced fed‐batch fermentation for an Escherichia coli whole‐cell biocatalyst containing an oleate hydratase. Operation at a higher growth rate markedly increased biomass yields while maintaining catalyst activity and was demonstrated at 150 L scale.

Challenges in meeting the mass transfer demands of high‐density perfusion cultures in single‐use bioreactors

Biotechnology Progress, EarlyView.
Abstract Increasing protein therapeutics production by adopting intensified perfusion cultures places high demand on the mass transfer capabilities of single‐use bioreactors (SUB). Here, we compare these capabilities for four SUB designs against worst‐case O2 transfer requirements for supporting Chinese hamster ovary (CHO) perfusion cultures. Impact of

Gas Turbine Health State Determination: Methodology Approach and Field Application

International Journal of Rotating Machinery, 2012
A reduction of gas turbine maintenance costs, together with the increase in machine availability and the reduction of management costs, is usually expected when gas turbine preventive maintenance is performed in parallel to on-condition maintenance ...

Techno‐Economic Assessment of Biomethane and Biohydrogen Production From Victorian Wheat Straw

Carbon Energy, EarlyView.
Techno‐economic assessment of biomethane and biohydrogen production from Victorian wheat straw. Off‐grid renewable photovoltaic energy with a price down to 0.95 ¢/kWh was applied. Both approaches can make positive profits and negative carbon footprints.

Automated Process Optimization in a Novel Triple Shaft Mixer with Adaptive Mixing Modes

Chemie Ingenieur Technik, EarlyView.
A novel multi‐purpose mixer with adjustable blade angle and a coaxial stirrer is developed, providing three degrees of freedom. An optimization strategy is integrated to autonomously identify optimal operating conditions through automated tests. The current draw of the main stirrer serves as the optimization criterion, while stirrer speeds, directions,

Prospective LCA of E‐Methanol Along the Transformation of Steel Industry

Chemie Ingenieur Technik, EarlyView.
The environmental effects of change in steel production route on e‐methanol production are analyzed as they shift from blast furnace route to direct reduction route. Specific hydrogen demand reduces, as do the avoided CO2 emissions. E‐methanol's overall carbon footprint stays in a narrow range of −1 to −1.1 kg‐CO2‐eq./kg‐methanol.

Laminar Burning Velocity of Ammonia‐Hydrogen Mixtures Predicted by Machine Learning

Chemie Ingenieur Technik, EarlyView.
Ammonia–hydrogen blends aid defossilization, but slow combustion kinetics require complex modeling. Although chemical kinetic modeling is computationally expensive, machine learning surrogates offer fast predictions. This study trained GPR, DT, and ANN models on 1445 experimental points.
