| Summary: | Natural gas dehydration by absorption using triethylene glycol (TEG) is one
of the most effective techniques with high efficiency. There are many processes
using this approach but any of them is able to combine the high performance and the
economic energy consumption. In this study water hydrocarbon phase behavior was
determined for different gas dehydration unit. The effects of the operating conditions
of the gas dehydration unit in determining the outlet gas dew point and water content
remaining in dry gas were studied by means of simulation run using ASPEN HYSYS
software. DRIZO process showed the most significant change of water dew point
curve followed by conventional stripping gas dehydration process and then the
typical gas dehydration process. At the other hand, study was done on improving the
absorption capacity of TEG as the water absorbent by adding additives to the
absorbent. Lastly, comparisons between theoretical and simulation results are
justified to determine whether it shows a good validation of the results to meet the
requirements of current industry practices. |
