T1 - Comparison of various heat pump assisted distillation configurations. AU - Fonyo, Z. AU - Benkö, N. PY - /1/1. Y1 - /1/1. N2 - Various heat pump assisted process configurations are analysed for two industrial case studies using a design strategy based on preliminary screening, rigorous steady state simulation and economic by: The economics and environmental impact of heat pump-assisted distillation was investigated and compared with those of conventional distillation. The depletion of fossil fuels and environmental pollution (e.g., greenhouse gas emissions) through the combustion of fossil fuels have stimulated studies on new technologies able to curtail the energy Cited by: 4.
Basic concepts in distillation --Design, control, and economics of distillation --Dividing-wall column --Optimal operation and control of DWC --Advanced control strategies for DWC --Applications of dividing-wall columns --Heat pump assisted distillation --Heat-integrated distillation column --Cyclic distillation --Reactive distillation. Distillation is the process of separating the components or substances from a liquid mixture by using selective boiling and lation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases .
Advanced Distillation Technologies: Design, Control and Applications Anton A. Kiss pages April Description Distillation has historically been the main method for separating mixtures in the chemical process industry. However, despite the flexibility and . Distillation Design and Control Using Aspen Simulation introduces the current status and future implications of this vital technology from the perspectives of steady-state design and dynamics. The book begins with a discussion of vapor-liquid phase equilibrium and then explains the core methods and approaches for analyzing distillation columns.

This chapter explains the working principle and describes the most promising heat pump (HP) systems – such as VC, MVR, TVR, AHP, CRHP, TAHP, HIDiC Heat pump assisted distillation.
book that can be used to upgrade the low quality energy from the condenser to drive the reboiler of a distillation column. In book: Advanced Distillation Technologies: Design, Control and Applications, pp Although the economics of heat pump assisted distillation systems appear to be attractive for certain.
Heat pump assisted distillation research is also extended to absorption heat transformer (AHT), the reverse operation of the absorption heat pump. In the transformer (Fig. 2), the absorber and evaporator operate at higher pressure, whereas the condenser at the lowest by: Heat Pump Assisted Distillation.

Several heat pump concepts were proposed to upgrade that discharged energy and reduce the consumption of valuable utilities.
This chapter explains the working principle. Heat pump assisted distillation can be applied to classic columns (Kiss et al., ) but only to a lesser extent to dividing-wall columns (Chew et al., ) as the temperature span across the DWC is larger. Novel Heat-Pump-Assisted Extractive Distillation for Bioethanol Purification Article (PDF Available) in Industrial & Engineering Chemistry Research 54(7) February with To solve this problem, we propose here a novel heat-pump-assisted extractive distillation process taking place in a dividing-wall column (DWC).
In this configuration, the ethanol top vapor stream of the extractive DWC is recompressed from atmospheric pressure to over bar (thus to a higher temperature) and used to drive the side reboiler of.

In the C4 splitter, the annualized capital cost for heat pump-assisted distillation is higher than for the conventional distillation, whereas the annual operating cost of the conventional distillation is higher than that of the heat pump-assisted distillation, as shown in Figure 3a,b.
The main reasons behind the increase in the annualized Cited by: 4. Abstract. When considering a separation process there are two entirely different interpretations of the word “efficiency”. The first refers to product purity (i.e. separation efficiency) and can be regarded as a pointer to the theoretical possible improvements of separation in the given process, considering the separation unit as a set of theoretical (equilibrium) by: 2.Extension of Heat Pump/Heat Engine 7 | Page Performance evaluation and modelling of a conventional absorption heat pump and distillation operation.
