Abstract
This study is concerned with utilization of waste heat liberated from a white cement plant in order to increase energy efficiency. Steam Rankin cycle was compared with steam-organic combined Rankin cycle (cascade organic Rankin cycle). This comparison depended on both thermodynamic and economic calculations. Thermodynamic comparison was based on the net power generated, thermal efficiency and irreversibility. Economic comparison was based on total project capital cost and rate of return. This study aimed to maximize the net power generated, thermal efficiency and rate of return; and to minimize irreversibility and capital cost. Three (SRC) and three (S-ORC) different schemes were suggested to recover waste heat from waste streams. Aspen HYSYS v9.0 was used to simulate suggested schemes. Iso-penate and its different isomers- n-penatne, cyclo-pentane, spiro-pentane and 2, 2-dimethylpropane- were selected as working fluids for steam-organic combined Rankin cycle
