Heat Pump Efficiencies Simulated with Aspen HYSYS and Aspen Plus [PDF]

Linköping Electronic Conference Proceedings, 2015
The efficiency of a heat pump system has been calculated for varying temperature conditions, refrigerants, simulation programs and thermodynamic models. Evaluated components are ammonia, the chlorofluorocarbons R-11, R-12, R-22 and propane. The equations of state Peng-Robinson (PR) and SoaveRedlich-Kwong (SRK) and the activity model NonRandom-Two ...

An elastic segment of the whisker shaft enables coding of the whisking phase via whisker torsion in rats and mice

The Anatomical Record, EarlyView.
An elastic segment was found in the basal part of the whisker shaft in rats and mice. Application of force to the whisker bulb of isolated follicles caused bending and twisting of this segment. Active whisker movements deform this segment, causing whisker shaft deflection and selective activation of mechanoreceptors at different phases of whisking ...

Volumetric mass transfer and dilution rate as key parameters for sustainable industrial syngas fermentation to isopropyl alcohol: modeling and parametric assessment

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Synthesis gas fermentation is a promising route for the valorization of steel mill off‐gas and for replacing conventional fossil‐based isopropyl alcohol (IPA) production. A recent 120 L pilot‐scale study reported 85% gas conversion at 90% product selectivity and claimed a negative global warming potential (GWP) without detailed process design.

Potential contribution of biomass gasification‐based technology in energy transition: a technical review coupled with bibliometric studies

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biomass gasification technology has been extensively researched around the world; however, there is a need to evaluate the current research landscape and evolutionary direction of research in the broader context of energy transition. A systematic bibliometric analysis of the Web of Science database was performed for articles that fall within ...

Sustainable and cost‐effective process design for energy‐self‐sufficient ethyl lactate production from sugar mill feedstocks: a techno‐economic approach

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Bio‐based ethyl lactate (EL) can replace several fossil‐derived products owing to its low toxicity, high solvent functionality, and environmental advantages. This study assesses the techno‐economic viability and greenhouse gas (GHG) reduction potential of producing EL from sugarcane A‐molasses and lignocelluloses in an energy self‐sufficient ...

Process development priorities for scaling up direct microbial conversion of sugars into value‐added biochemicals

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The study identified process development priorities toward the feasible production of five value‐added biochemicals in a sugarcane biorefinery based on achievable bioconversion performances. Multiple process scenarios using A‐molasses as feedstock were simulated in Aspen Plus® via direct microbial conversions.

Development of a co‐culture of Ureibacillus thermosphaericus and Cupriavidus taiwanensis for inhibitors removal from hemicellulose prehydrolysate

Biotechnology Progress, EarlyView.
For biofuels production, hemicellulose pre‐hydrolysate is considered as an attractive feedstock rich in fermentable sugars. The pre‐hydrolysate derived from lignocellulosic biomass comprises, along with sugars, several inhibitors which can hamper its efficient conversion.
