Abstract: “Subsea processing enables broader exploration of oil and gas reservoir, giving an increased focus on developing alternative processes for subsea oil and gas treatment. This work provides a first evaluation of a new proposed subsea natural gas dehydration process with the use of a membrane contactor with triethylene glycol (TEG) for dehydration of the natural gas in combination with thermopervaporation for regeneration of the TEG. Simulation models are developed in Aspen HYSYS V8.6 and process optimization is performed on three different process designs with respect to staging of the regeneration…”

Comments: the authors are using a MATLAB CAPE-OPEN Unit Operation (AmsterCHEM) to model a membrane contactor. The CAPE-OPEN Unit Operation is plugged into Aspen HYSYS v8.6 and used to optimize a subsea natural gas dehydration process.
