| Opis: | In addition to the consumption of hot utilities, there is also a significant cost associated
with the consumption of cold utilities when there is a high demand for cooling. A promising
solution for cooling is an absorption chiller (AC), which uses heat instead of electricity for cooling.
A thermodynamic approach for evaluating AC integrated with a process is presented in this work.
A model for assessing the properties and duties of an AC cycle was developed. The integration of
a combined process-AC system was evaluated using the Grand Composite Curve. Three different
options of integration were analyzed: (i) above the Pinch, (ii) below the Pinch, and (iii) across the
Pinch. AC represents the combined effect of a heat engine and a heat pump, as the generator together
with the absorber and condenser has the function of a heat engine, while the evaporator combined
with the absorber and condenser mimics the function of a heat pump. The comparison between the
non-integrated and integrated process-AC systems has revealed that the proper placement of AC is
across or below the Pinch and the improper is above the Pinch. If AC was entirely integrated below
the Pinch, the integration would result in a complete (100%) reduction in the consumption of hot
utility for the operation of AC. The most suitable placement of AC with double reduction of hot
utility consumption and complete reduction of both hot and cold utility to operate AC is across the
Pinch due to the pumping of heat through AC from below to above the Pinch. |
