Abstract: In one aspect, assemblies for removing water from hydrocarbon liquids are described herein. An assembly described herein comprises a coalescer element having interior and exterior surfaces and comprising a porous support tube and a medium positioned within the porous support tube, the medium having a structure for coalescing water droplets in the hydrocarbon liquid passing though the medium. A separation medium encloses the exterior surface of the coalescer element and is spaced apart from the exterior surface of the coalescer element. The separation medium comprises a barrier region for collecting coalesced water droplets in the hydrocarbon liquid exited from the coalescer element and a release region for releasing coalesced water droplets from the assembly.
