This paper presents both the results of a study existing heat exchanger network (HEN) an industrial unit for ethylbenzene (EB) production by alkylation benzene with ethylene, and analysis four different HEN retrofit projects carried out using process integration methods. The project modernization was classical methods Pinch analysis. For this case, value ΔTmin is determined, which limited techn...

For its high coefficient of performance and zero local emissions, the heat pump (HP) has recently become popular in North Europe and China. However, the integration of HPs may aggravate the daily peak-valley gap in distribution networks significantly.

h THREE-DIMENSIONAL INTEGRATION HAS been considered one of the most promising breakthrough technologies achieving higher integration density, better performance, lower power consumption, and smaller form factor. Enabling 3-D integration, however, requires innovation and advancement in manufacturing technology, modeling, design methodologies, and optimization algorithms for physical layout, circ...

Abstract Heat integration by pinch method is used to modify the heat exchanger network of an industrial ethylene glycol plant. The aim reduce energy cost operating plant close maximum recovery. Pinch analysis identified a temperature 483 K, minimum heating utility 13,490.9 MJ/ton EO, and cooling 25,697 EO. Using decomposition diagram standard procedure for matching hot cold streams, retrofit ex...

In the energy transition, multi-energy systems are crucial to reduce temporal, spatial and functional mismatch between sustainable supply demand. Technologies as power-to-heat (PtH) allow flexible effective utilisation of available surplus green electricity when integrated with seasonal heat storage options. However, insights methods for integration PtH in lacking. Therefore, this study, we dev...
