The system includes a lean solvent feed system, including a line from a topsides facility, wherein the line is configured to divide a lean solvent stream to feed lean solvent to each of a number of co-current contacting systems in parallel. The co-current contacting systems are placed in series along a wet natural gas stream, wherein each of the co-current contacting systems is configured to contact the lean solvent stream with the wet natural gas stream to adsorb at least a portion of the water from the wet natural gas stream to foiin a dry natural gas stream. A rich solvent return system includes a line to combine rich solvent from each of the plurality of co-current contacting sys - tems and return a rich solvent stream to the topsides facility. \"Vale and off-gases . c 144 X18 2 Hydrocarbon stream 10o FIG. 1 WO 2017/087056 Al MIONIMOREIDEDIDEMEDIMMICHIMEIHMEMOIS Declarations under Rule 4.17: Published: as to applicant's entitlement to apply for and be granted with international search report (Art 21(3)) a patent (Rule 4.17(ii)) as to the applicant's entitlement to claim the priority of the earlier application (Rule 4.17(0)
