摘要： This method consists of the introduction of a load current (54) in a first tank (22), the dynamic expansion of the gas current (56) emanating from the tank (22) in a turbine (24), then its introduction into a first purification column (26). It comprises the production at the top of the first column (26) of purified gas (70) and the recovery at the bottom of the first column (26) of a liquefied bottom gas (74), which is introduced after expansion into a second column (30) for elimination of C
5 + hydrocarbons. The purified top natural gas (70) from the first column (26) is reheated in a first heat exchanger (20) by heat exchange with a load gas (12). The method comprises the compression of top gas current (86) in second column (30) in a compressor (38) before it is introduced into a second separator tank (40).

摘要： Contemplated plants for recovery of NGL from natural gas employ alternate reflux streams in a first column and a residue gas bypass stream, wherein expansion of various process streams provides substantially all of the refrigeration duty in the plant. Contemplated plants not only have flexible recovery of ethane between 2% and 90% while recovering at least 99% of propane, but also reduce and more typically eliminate the need for external refrigeration.

摘要： A method for separating one or more C2+ hydrocarbons from a mixed phase hydrocarbon stream such as partly vapourised liquefied natural gas, the method at least comprising the steps of : (a) supplying a mixed phase hydrocarbon feed stream (10) to a first gas/liquid separator (12); (b) separating the hydrocarbon feed stream (10) in the first gas/liquid separator (12) into a first gaseous stream (20) from a first outlet (23) and at least one C2+ liquid stream (30); (c) passing the first gaseous stream (20) through a compressor (14) to provide a compressed stream (60); and (d) cooling the compressed stream (60) in one or more heat exchangers (16) to provide an at least partly condensed hydrocarbon product stream (70); wherein a second gaseous stream (40) is added to a stream (20, 60, 70) downstream of the first outlet (23).

摘要： Process for treating on floating units fluid from submarine oil fields, inclu­ding the following stages: -delivering the fluid (1) to a high pressure separation stage (S-HP) in which the fluid is split into a light hydrocarbon gas phase (2), a water phase (3) and a hydrocarbon liquid phase (4); -delivering the light hydrocarbon gases (2) to a gas reinjection compression unit (C-HP), having at least two compression stages (Cl,C2,C3); -delivering the hydrocarbon liquid (4) to one or more-further separation stage: operating at decreasing pressures (S-IP and S-LP), where said liquid (4) is split into a light hydrocarbon gas phase (5,8), a water phase (6,9) and a li­quid hydrocarbon phase (7); -delivering the light hydrocarbon gases (5,8) to compression units 'Flash Gas Jet Compression' (FGJC), comprising ejectors (El,E2) which use the compressed gas (21,22) from the gas reinjection compression unit (C-HP) as driving fluid.

摘要： A process for separating gaseous or liquid hydrocarbons in first and second fractionation zones wherein the first frac­tionation zone (36) employs a side reboiler (45) discharging below the side draw point. A vapor sidestream (47) is removed from the first frac­tionator (36) below the side draw point and introduced to the second fractionator (48). The flow scheme permits control of the first fractionator bottoms temperature to match available low level waste heat which may therefore be used in fractionator reboiling duty.
