Patent number: 8640493Abstract: Method for processing, treatment and liquefaction of natural gas proximate offshore gas fields with a gas floating production storage and offloading vessel with a primary processing unit, a gas treating unit, and a natural gas compressor. The liquefaction is split between a liquefied natural gas transport vessel moored on a disconnectable turret and the floating production storage and offloading vessel. High pressure liquefied natural gas inlet quality gas from the vessel is sent through conduits to the liquefied natural gas transport vessel(s) then back through the disconnectable turrets to the vessel. A separate nitrogen refrigerant on the transport vessel provides final stage liquefaction while being powered by the transport vessel's propulsion plant. When the transport vessel is full, the transport vessel disconnects from the disconnectable turret, and motors to a transfer terminal located in sheltered water for transfer of liquefied natural gas cargo to a standard trading tanker.Type: GrantFiled: March 20, 2013Date of Patent: February 4, 2014Assignee: FLNG, LLCInventors: Robert Magee Shivers, III, Richard Paul Michel, Marcus LaRoy Morris, Ned Phillip Baudat, Norman Paul Kolb

Patent number: 8590339Abstract: In method of providing uniformity of vapor and liquid phases in two or more streams derived from a mixed vapor and liquid stream (10), the mixed vapor and liquid stream (10) passes from a first heat exchanger (101) into a distribution vessel (12) via one or more inlets (14). The distribution vessel (12) has two or more outlets (16) connected to a second heat exchanger (102). The liquid part of the mixed stream (10) is allowed to collect in a first area (20) in the distribution vessel (12), and the vapor part of the mixed stream (10) is allowed to collect in a second area (30) of the distribution vessel (12), preferably above the first area (20). The liquid in the first area (20) passes into the outlets (16) via one or more liquid apertures (18) in each outlet (16) that communicate with the first area (20), and the vapor in the second area (30) passes into the outlets (16) via one or more vapor apertures (28) in each outlet (16) communicating with the second area (30).Type: GrantFiled: November 20, 2007Date of Patent: November 26, 2013Assignee: Shell Oil CompanyInventor: Johan Jan Barend Pek
