A method for receiving fluid from a natural gas pipeline, the fluid comprising gaseous hydrocarbons, liquid hydrocarbons, water and optionally solids, the method comprising: (a) in a slug catcher (), receiving the fluid comprising gaseous hydrocarbons, liquid hydrocarbons, water and optionally solids from at least one pipeline () (b) in the slug catcher (), separating at least a portion of the gaseous hydrocarbons from the rest of the fluid to leave a liquid mixture or a liquid/solid mixture; (c) directing at least a portion of the liquid mixture or liquid/solid mixture to a separation vessel (), preferably a three-phase separation vessel; and (d) in the event of a surge of liquids and optionally solids to the slug catcher (), directing at least a portion of the liquid mixture or the liquid/solid mixture from the slug catcher () to a surge vessel ().

Method for receiving fluid from a natural gas pipeline

A process for the preparation of liquid hydrocarbons from a light hydrocarbonaceous feedstock in combination with a process for liquefying natural gas, which liquefaction process involves the steps of

Process for liquefying natural gas and producing hydrocarbons

Liquefying a stream enriched in methane comprising a) supplying a natural gas stream to scrub column, removing in the scrub column heavier hydrocarbons from the natural gas stream to obtain a gaseous overhead stream withdrawn from the top of the scrub column, partly condensing the gaseous overhead stream and removing from it a condensate stream, which is returned to the upper part of the scrub column as reflux; b) liquefying the stream enriched in methane in a tube arranged in a main heat exchanger by indirect heat exchange with a multicomponent refrigerant evaporating at low refrigerant withdrawn from the shell side of the main heat exchanger and partly condensing it at an elevated refrigerant pressure, and c) compressing the multicomponent refrigerant pressure in a tube arranged in an auxiliary heat exchanger by indirect heat exchange with an auxiliary multicomponent refrigerant evaporating at low auxiliary refrigerant pressure to obtain multicomponent refrigerant for use in step b), wherein partly condensing the gaseous overhead stream is done in a tube arranged in the auxiliary heat exchanger.

Reducing the amount of components having low boiling points in liquefied

A method is provided for removing carbon dioxide, ethane and heavier components from high pressure natural gas (10) comprises: partly condensing and expanding the high pressure natural gas (10) to obtain a gaseous stream (30) enriched in methane and carbon dioxide and two liquid streams (37 and 40) enriched in ethane and heavier components which are introduced into fractionation column (35); removing from fractionation column (35) fluid stream (45), heating (46) the fluid stream to obtain a reboiling stream (47) which is introduced into the fractionation column (35); removing from fractionation column (35) liquid stream (50) enriched in carbon dioxide, ethane and heavier components; removing from the top of fractionation column (35) a gaseous overhead stream (55) enriched in methane; cooling (56) the gaseous overhead stream (55) to obtain a two-phase fluid, separating (58) the two-phase fluid into cooled gaseous overhead stream (60) and first reflux stream (62) which is introduced into the fractionation column (35); and expanding (65) the cooled gaseous overhead stream (60) to obtain a two-phase fluid at low pressure, separating (69) the two-phase fluid into gaseous product stream (70) and second reflux stream (72) which is introduced into the top of the fractionation column (35).
