This work is aimed at investigating the benefits of replacing conventional process unit operationsudwith process intensified ones in offshore applications. This ensures that better use is made of rawudmaterials, lower energy consumption and a reduced plant volume was achieved. Specifically, audrotating packed bed technology has been used for gas dehydration and sweetening. To achieve the aim of this study, a process intensification approach is used to redesign mature absorptionudprocesses to more compact and efficient one. Process simulation using Aspen Hysys was carriedudout for Triethylene glycol dehydration and monoethanolamine sweetening. More than 36-foldudabsorption unit size reduction was achieved thereby effecting large decrease in capital andudoperating costs compared to the conventional packed columns currently utilized in the offshore oiludand gas industry. The process intensified technologies therefore can be deployed for offshoreudapplications where space and size considerations are of utmost importance.
