WebA través de un diseño correcto de la red de intercambiadores de calor, el análisis pinch indica de qué modo se pueden aprovechar aquellas corrientes calientes y frías de una planta, para intercambiar calor entre ellas, minimizando así el uso de servicios de calentamiento o enfriamiento. Web19 de feb. de 2016 · A typical plant requires the use of many individual heat exchanger units. This combined process heating and cooling of a plant could be accomplished through the use of utilities, but this will be very costly in term of capital and utility costs. Heat exchanger networks utilize multiple heat exchanger units to optimize the process design.
Web22 de may. de 2024 · Pinch Point – Heat Exchanger There is another interesting aspect to the design in that the temperature difference known as ‘pinch’ can limit the performance of heat exchangers if the areas and flow rates are not properly designed. Web19 de feb. de 2016 · Heat exchanger networks are designed through insightful use of pinch analysis. The pinch point divides the temperature range into two regions. Pinch point analysis is a tabular procedure that is a convenient alternative to the construction and analysis of hot and cold composite curves.
