Most natural gas producers use triethylene glycol (TEG) to remove water from the natural gas stream in order to meet the pipeline quality standards. In designing such a process, it is crucial that the size of the inlet scrubber as well as the gas/glycol contactor is correctly estimated. The aim of this study is therefore to develop simple-to-use correlations for appropriate sizing of the inlet scrubber and contactor covering a wide range of operating conditions of TEG dehydration systems. Results illustrate that a designer may consider these correlations as appropriate estimation tools during the design of a gas dehydration system utilizing TEG solvent.
