Abstract
The condensate stabilization unit is one of the most important operational units in gas processes. In this unit, the raw condensate is stabilized through a distillation system. This research has investigated the energy, exergy and economic costs by simulating and analyzing the process. In this study, the effect of parameters such as feed flow rate and temperature on energy and exergy performance has been evaluated. The process simulation has been performed using Span Hysys software and the Peng-Robinson equation of state. In order to optimize, the feed preheating method has been used instead of air cooling in the lower part of the column, which has reduced the exergy destruction by 57.91 kW. Also, a heat exchanger has transferred heat by 333.2 kW between the hot and cold streams. The results show that the total process energy consumption has decreased from 1502.98 kW to 1003.94 kW and the exergy efficiency of the stabilization column has increased from 66.11% to 88.21%. In the optimized structure, the total irreversibility of the system has decreased from 257.4 kW to 165.83 kW. This reduction is equivalent to 103.4 kW of exergy destruction of the stabilization tower, which has led to energy storage and improved quality of its consumption.
