This was done by bringing into account the water profile. The water inlet temperatures were implemented at 10, 20 qnd 30°C. The system was simulated with gas cooler outlet temperatures of 288, 298 and 308K respectively at the different water inlet temperatures. These were all simulated at evaporating temperatures of 273,278 and 283K and at discharge pressures of 9000 and 10000kPa. All the runs were plotted on a temperature-entropy (T-s) diagram and are shown in the following figures. The routine followed was as follow: • • • • For an evaporating temperature of 0 degrees and water inlet temperature of 10 degrees the gas cooler outlet temperature were changed between 288, 298 and 308K. For an evaporating temperature of 0 degrees and water inlet temperature of 20 degrees the gas cooler outlet temperature were changed between 288, 298 and 308K. For an evaporating temperature of 0 degrees and water inlet temperature of 30 degrees the gas cooler outlet temperature were changed between 288, 298 and 308K. The same was done for an evaporating temperature of 5 and 10 degrees. The results for 10000kPa, an evaporating temperature of 0 degrees and the gas cooler outlet temperature being changed from 288K, to 298K and to 308K are shown.
