摘要： A method and system for the offshore production of fuel includes an offshore marine platform on which is mounted an ammonia production unit. The ammonia production unit may produce ammonia utilizing raw materials sourced adjacent the marine platform, including seawater and electricity from offshore wind turbines. The produced ammonia may be subsequently liquified and transported away from the marine platform, or conveyed to a remote location via a seabed pipeline. A portion of the hydrogen produced as part of the ammonia production process may be utilized to operate onboard combustion turbines that can in turn drive electric generators onboard the marine platform to produce electricity.

摘要： A reverse osmosis filtration system includes a set of two or more reverse osmosis pressure vessels coupled in series, each pressure vessel having one or more reverse osmosis membrane elements, a feed inlet, a retentate outlet, a permeate outlet. The pressure vessels are coupled so that each successive pressure vessel has (a) its feed inlet coupled to the retentate outlet of its preceding pressure vessel and (b) its permeate outlet coupled to the permeate outlet of its preceding pressure vessel. The permeate outlet of at least one pressure vessel includes a front permeate outlet and the permeate outlet of at least one other pressure vessel includes a back permeate outlet. The back permeate outlet of one pressure vessel is coupled to the front permeate outlet of a successive pressure vessel.

A plurality of elongated filtration membrane stacks are positioned side-by-side in the casing generally parallel to the longitudinal axis. Each filtration membrane stack includes an intake end which is fluidly connected to the intake collection chamber, a discharge end which is fluidly connected to the reject collection chamber, and a permeate channel which extends between the intake and discharge ends and is fluidly connected to the discharge collection chamber, an end of the permeate channel located adjacent the intake end being sealed from the intake collection chamber. The filtration apparatus also includes an intake pipe having a first end fluidly connected to the intake collection chamber and a second end fluidly connected to a first connector located proximate the second casing end; a discharge pipe having a first end fluidly connected to the discharge collection chamber and a second end fluidly connected to a second connector located proximate the first connector; and a reject pipe having a first end fluidly connected to the reject collection chamber and a second end fluidly connected to a third connector located proximate the first and second connectors. Each filtration membrane stack includes a plurality of filtration membranes, and the plurality of filtration membrane stacks together define a plurality of axially successive sets of radially adjacent filtration membranes. Also, each filtration membrane of each of the sets of filtration membranes is sealed to a corresponding hole in a respective one of the partition plates.
