text: "ABSTRACT\r\n \r\n Electrification
offers a promising route to reduce CO\r\n 2\r\n
\ emissions in the chemical sector. In distillation, heat pump
integration such as mechanical vapor recompression (MVR) can replace fossil‐based
utilities, but column parameters like pressure drop should be accurately considered
when assessing integration potential. This work discusses the effect of feed preheating
and column pressure drop on MVR integration potential. The two binary separation
tasks, methanol–water and benzene–toluene, are analyzed to identify energetically
optimal preheater and MVR design. In addition, MVR integration in a bioethanol
vacuum distillation sequence is evaluated for utility demand, CO\r\n 2\r\n
\ emissions, and economic feasibility under varying pressure
drops, preheating configurations, and cost and emission scenarios.\r\n "

text: "ABSTRACT\r\n Separation
processes, such as distillation and stripping, are highly energy‐intensive. Typically,
energy is supplied indirectly via a reboiler, which is often associated with heat
losses. We present a preliminary theoretical evaluation of a novel concept to
supply energy directly inside the column using heatable structured packings. These
packings can be produced by multi‐material 3D printing, resulting in a conductive
inner layer and an insulating outer layer. Functioning as electric resistance
heaters, these packings serve as heating elements. In this numerical study, we
compared different scenarios of energy supply along the height of the column,
including uniform distribution, applying a temperature profile, and using or omitting
a reboiler."

text: "ABSTRACT\r\n This study
shows the applicability of ultrasonic sensors for measuring two‐phase layer heights
in sieve tray columns under dynamic operating conditions. Although these sensors
are known for their precision in stationary systems, their reliability under fluctuating
flow conditions has remained unclear. To validate their accuracy, ultrasonic measurements
were compared with both automated image analysis via a Python algorithm and manual
video evaluation. Results show that ultrasonic sensors maintain high precision
at moderate gas loads and with small hole diameters. Increased gas loads and turbulence,
however, reduced measurement accuracy due to signal scattering. The findings highlight
the potential of ultrasonic sensing for real‐time, noninvasive monitoring in dynamic
multiphase systems."

text: The joining of dissimilar materials, such as steel and aluminum, entails significant
challenges during thermal curing processes due to differing coefficients of thermal
expansion. This study addresses the formation of “viscous fingering” instabilities
in structural adhesive joints, which are induced by thermally driven relative
displacements during the liquid phase of the adhesive. Using a component-like
specimen “bridge specimen,” the dependency of this phenomenon on process temperature
and structural stiffness (rivet distance) was characterized. Experimental results
reveal that while the relative displacement scales cubically with the free buckling
length, the resulting adhesive area reduction follows an exponential trend, leading
to a loss of effective bond area of up to 79%, which significantly compromises
the joint strength in automotive applications. To predict these process-induced
defects, a thermo-chemo-viscoelastic-viscoplastic adhesive model implemented in
LS-DYNA was applied. The model combines curing kinetics, viscoelastic relaxation,
and pressure-dependent plasticity and features a geometric damage parameter (D)
that captures the adhesive area reduction caused by viscous fingering as an exponential
function of the accumulated normal strain in the liquid phase. This damage parameter,
calibrated on base-specimen level, was transferred to the component geometry.
The simulation demonstrated high predictive accuracy with a maximum deviation
of the adhesive area reduction of 3.1% compared to experimental data. This validates
the model’s capability to predict manufacturing-induced damage in complex hybrid
structures solely based on thermal boundary conditions.

text: "ABSTRACT\r\n \r\n The
integration of heat pumps offers a promising route for electrifying chemical processes
and reducing CO\r\n 2\r\n emissions.
Their feasibility strongly depends on the temperature levels and the quantities
of available heat sources and sinks, which can be influenced by adjusting process
operating parameters to enhance integration potential. The number and quality
of these sources and sinks also determine suitable heat pump configurations and
therefore the technical and economic viability of implementation. In addition,
refrigerant selection is a critical factor, as it is restricted by regulations
such as the F‐Gas Regulation. This study investigates how different operating
parameters affect the integration potential of various heat pump configurations
in a CO\r\n 2\r\n absorption
process using MEA as solvent. Furthermore, economic evaluations are carried out
considering different electricity price scenarios and allowable refrigerants.\r\n

text: The reduction of CO2-emissions in the chemical industry is essential
to meet European climate targets. Particularly, the reliance on fossil fuels for
process heat supply is a key factor for CO2-emissions. Electrically driven compression
heat pumps are a promising option to reduce fossil fuel consumption by upgrading
low-temperature waste heat to a higher temperature level, provided that low-carbon
electricity is available. However, the integration of heat pumps into chemical
utility systems remains a challenge due to economic constraints and the high complexity
associated with site-wide heat integration and retrofit of existing structures.
This work presents a mixed-integer linear programming (MILP) approach for the
optimization of utility systems with integrated heat pumps. To address computational
complexity, candidate utility temperature levels are pre-selected, and feasible
heat pump coefficients of performance (COP) are precomputed. The framework is
applied to both greenfield and retrofit scenarios for a synthetic case study consisting
of 400 process streams. In the greenfield scenario, optimal utility temperature
levels and heat pump integration configurations are identified. For the retrofit
scenario, temperature levels of an existing utility system are modified to reduce
total annual costs (TAC). Additionally, sensitivity analysis is conducted to assess
the influence of key economic and environmental parameters. The presented case
studies demonstrate short solution times, highlighting the suitability of the
proposed framework for screening studies and systematic sensitivity analyses in
early-stage design and retrofit applications.

text: Heat pumps offer the possibility of reducing CO2-emissions in the
chemical industry. However, the integration of heat pumps, especially in non-continuous
processes, faces several challenges. Energy storage facilitates a way to enhance
heat integration by providing a continuous supply of heat flows. By doing so,
the question arises as to whether this implementation should be applied to the
process or to the utility level. At the process level, there is usually more freedom,
as one is not bound by the existing temperature levels of the utility system,
which are mostly difficult to retrofit. Therefore, this study presents an approach
that generates heat integration concepts at the process level based on two different
criteria. These criteria influence which process streams are grouped for a storage
implementation and therefore influence the heat integration. The aim is to maintain
the heat flows as continuous as possible by integrated heat storages. Finally,
the possible heat integration concept is evaluated in terms of energy efficiency
by a know method for continuous process streams, here the pinch analysis.

text: "ABSTRACT\r\n \r\n Methane,
synthesized from renewable hydrogen and biogenic CO\r\n 2\r\n
\ , can be a part of the transformation towards renewable energy
carriers. A major engineering challenge is the optimization of the fixed‐bed reactor
design, specifically the heat dissipation in regions of high reaction heat release.
A mitigation concept is the introduction of inert material into the fixed bed,
called catalyst dilution. In this study, a 1D continuity model is presented, which
aims to predict catalyst superheating. This model is used in an exploratory study
to identify system sensitivity and optimization parameters. Subsequently, an optimization
framework for improving the reactor design is tested, resulting in a 148‐K reduction
in peak catalyst temperature when using a 33.3 vol% catalyst dilution.\r\n "

text: Pillow-plate heat exchangers (PPHEs) represent a viable alternative to conventional
shell-and-tube and plate heat exchangers. The waviness of their channels intensifies
fluid mixing in the boundary layers and facilitates heat transfer. Applying secondary
surface structuring can further enhance the overall thermo-hydraulic performance
of PPHEs, thus increasing their competitiveness against conventional heat exchangers.
In this work, streamlined secondary structures applied on the PPHE surface were
studied numerically to explore their potential in enhancing near-wall fluid mixing.
Computational fluid dynamics (CFD) simulations of single-phase turbulent flow
in the inner PPHE channel were performed and pressure drop, heat transfer coefficients,
and overall thermo-hydraulic efficiency were determined. The simulation results
clearly demonstrate a favourable influence of secondary structuring on the heat
transfer performance of PPHEs.

text: Heat pumps play a crucial role in decarbonizing the chemical industry. The
integration and sizing of heat pumps in chemical processes is a challenging task
in multi-product chemical processes due to the fluctuating waste heat supply and
heat demand. Integrating heat pumps may require a retrofit of the utility system.
Mathematical optimization is a useful tool to tackle this challenge by enabling
the analysis of correlation between relevant system parameters and equipment sizing.
This study demonstrates the utilization of mathematical optimization and parameter
studies for utility system equipment sizing addressing fluctuating heat supply
and demand profiles.
