Definitions
- the present invention relates to a process for cryogenically separating a natural gas feed stream into a gas containing the most volatile feed stream compounds and a liquid product containing the heavier compounds of the feed stream.
- NTL natural gas-associated liquids
- NGL Natural Gas Liquids
- natural gas for example such as ethane, butane, propane, hydrocarbons C5 + and C6 + (ie that is, having at least five carbon atoms and having more than six carbon atoms).
- Condensation of the flow at the de-ethanizer head is often done in part with the fluid from the absorber vessel.
- the inventors of the present invention have then developed a solution to solve the problems raised above.
- the present invention relates to a process as defined in claims 1 to 4.
- the invention also relates to an apparatus as defined in claim 5.
- the hydrocarbon stream to be liquefied is typically a stream of natural gas obtained from natural gas fields, oil reservoirs or a domestic gas network distributed via pipelines.
- the flow of natural gas is essentially composed of methane.
- the feed stream comprises at least 80 mol% of methane.
- natural gas contains quantities of hydrocarbons heavier than methane, such as, for example, ethane, propane, butane and pentane, as well as certain aromatic hydrocarbons.
- the natural gas stream also contains non-hydrocarbon products such as H2O, N2, CO2, H2S and other sulfur compounds, mercury and others.
- the feed stream containing the natural gas is thus pretreated before being introduced into the heat exchanger allowing the first cooling step of the method that is the subject of the present invention.
- This pretreatment includes reducing and / or eliminating undesirable components such as CO2 and H2S, or other steps such as pre-cooling and / or pressurizing.
- natural gas refers to any composition containing hydrocarbons including at least methane.
- the heat exchanger can be any heat exchanger, unit or other arrangement adapted to allow the passage of a number of flows, and thus allow at least one direct or indirect heat exchange system between one or more lines of heat. refrigerant, and one or more feed streams.
- a vaporizer-condenser bath is for example of the type as described in the patent application EP 1 087 194.
- the figure illustrates the diagram of an embodiment of an implementation of a method according to the invention.
- a natural gas feed stream 1 is introduced into a main heat exchanger 2 in order to be cooled.
- the gas thus cooled 3 is partially condensed and introduced into a pot phase separator 4.
- the gas phase 5 at the top of the phase separator pot 4 is introduced into a turbine 6 in order to recover the relaxation energy and to condense a part of the stream 5, then is introduced into an absorption column 7 comprising a lower part 7 'and an upper part 7 ".
- the liquid phase 8 in the tank of phase separator pot 4 is introduced after expansion 9 in the absorption column 7
- the absorption column produces a liquid in the bottom of the column and at the top of the column, a waste gas 11.
- the liquid 10 is heated in a heat exchanger 12 in which it is partially vaporised. introduced in the main exchanger 2, this introduction 13 is then strongly diphasic.
- the residual gas 11 containing only the more volatile products than ethane is heated in the main heat exchanger 2, the resulting stream 14 is then compressed and sent to a processing unit A.
- the stream 13 'at the outlet of the heat exchanger 2 coming from the tank of the absorption column 7 is introduced into a fractionation column 15.
- This column 15 produces in the tank 16, a reboiled liquid product 18 with the aid of a reboiler 17 in order to obtain a propane-rich liquid that is depleted of ethane.
- a gas 20 is produced.
- This gas 15 is condensed in the heat exchanger 12 and the product 21 leaving the exchanger 12 is introduced into a phase separator pot 22.
- the gas phase 23 at the top of the phase separator pot 22 serves as reflux to the column 7.
- the liquid in the tank of the phase separator pot 22 serves as reflux 26 at the top of the fractionation column 15.
- a pump is not necessary for pumping the liquid 25.
- a bath vaporizer-condenser has the advantage of being very easy to control while integrating the exchanger and the fractionation column and without using a pump (schematic thermo-siphon).
