Özet (Çeviri)
Distillation is the most popular separation method used in chemical industries. However, despite of its many known benefits and extensive use, high energy demand of the process still remains as major drawback of the distillation. Many methods of energy integration have been applied in order to moderate operating cost of distillation such as heat integration, heat pumping and thermal-coupling (Bruinsma, 2010). Heat pump technologies are one of the main energy saving technologies in distillation, efficiencies in the order of 50 % have been achieved (Bruinsma, 2010). Various heat pump technologies assist bulk distillation columns in reducing high operating costs and capital investments. Thermoacoustic heat pumps (TAHP) are one of the novel heat pump technologies which have been studied in this dissertation. Tijani, Zeegers et al. (2002) proposed a design strategy, which is based on linear thermoacoustic theory. The design strategy is used as a guide to design and optimize TAHP systems. The strategy proposes a dimensionless quantitive model to obtain acoustic power demand and the area requirement of TAHP. In order to conduct a proper evaluation of TAHP under different temperatures and different temperature lifts, the dimensionless model of TAHP is applied to three different distillation columns. Estimations were derived for acoustic power, electrical power and the required area for the application of TAHP to the base cases. Operating cost of TAHP is calculated based on the power demand which is also obtained from the model. The operating cost of the application TAHP to the base cases are compared with results for operating cost a conventional heat pump, vapour compression heat pump (CHP) and external utilities cost (cooling water and steam). COP of TAHP is found to be 3 to 4 times less than CHP which illustrates that application of TAHP to the selected cases does not bring any significant benefits in terms of energy saving compared to the application of CHP methods and using external utilities. This conclusion is also supported by calculating operating cost of TAHP, CHP and external utilities, which is also states that application of TAHP model does not bring any associated benefits. It is found out to that for the above ambient distillation using external utilities is worthwhile than both application of TAHP and CHP, and for the below ambient distillation, since the process cannot be satisfied by external utilities, using CHP is necessary and worthwhile.
