A Short‐Cut Design Approach to Evaluate Reboiler Designs in Vapor Recompression Scenarios

Chemie Ingenieur Technik, EarlyView.
A short‐cut model framework that incorporates mechanical vapor recompression (MVR) requirements into reboiler design is presented, which is particularly beneficial during early process development with limited data or initial feasibility assessments.

Smooth anti-reflective three-dimensional textures for liquid phase crystallized silicon thin-film solar cells on glass

Scientific Reports, 2017
Recently, liquid phase crystallization of thin silicon films has emerged as a candidate for thin-film photovoltaics. On 10 μm thin absorbers, wafer-equivalent morphologies and open-circuit voltages were reached, leading to 13.2% record efficiency ...

Nichtlineare Staubungsneigung binärer Schüttgutmischungen: Herausforderungen bei der Prognose Non‐linear dusting tendency of binary bulk material mixtures: Challenges in prognosis

Chemie Ingenieur Technik, EarlyView.
Aufgrund überlagerter oder konkurrierender Mechanismen sind relevante Wechselwirkungen bei der Staubung von Schüttgutmischungen komplex und nur unzureichend verstanden. Selbst für Mischungen aus umfassend charakterisierten Einzelkomponenten existieren keine belastbaren Modelle. In dieser Arbeit werden die Hürden bei der Prognose thematisiert.

Molekulare Solarthermiespeicher—zwei Fallstudien zur Optimierung Molecular solar thermal storage—two case studies on optimization

Chemie Ingenieur Technik, EarlyView.
Molekulare Solarthermiespeicher (MOST) überführen Licht in Wärmeenergie, die zu einem späteren Zeitpunkt genutzt werden kann. Die Optimierung solcher Systeme wird von vielen Parametern bestimmt, wie hier an zwei Beispielmolekülklassen, Azobenzole und Azaborinine, gezeigt.

Matching Heat Pump Configurations and Process Parameters for Cost‐Minimal Heat‐Integrated CO2 Capturing Process

Chemie Ingenieur Technik, EarlyView.
In a CO2 absorption process, it is investigated whether the adjustment of operating parameters facilitates the integration of different closed heat pump cycles considering various refrigerants. The influence of different integration concepts and electricity prices are investigated by means of resulting total annual costs.

Method for the Ecological and Economic Assessment of Mechanical Vapour Recompression in the WindaB Tool

Chemie Ingenieur Technik, EarlyView.
Method to assess economic and ecologic advantages of mechanical vapour recompression at early stage of development. Main correlations between design parameters and profitability as well as CO2 emission reductions are described shown in a case study of methanol–water.
