Definitions
- the present invention relates to a process for liquefying a hydrocarbon stream such as natural gas in particular in a process for the production of liquefied natural gas and liquid CO 2 .
- refrigerant streams are used to produce cold at different levels of a main heat exchanger by vaporizing against the hydrocarbon stream to be liquefied (typically natural gas).
- the present invention relates to a method of thermal integration between a natural gas liquefaction unit and a CO 2 purification / liquefaction unit.
- natural gas can be stored and transported over long distances more easily in liquid form than in gaseous form, because it occupies a smaller volume for a given mass and does not need to be stored at high pressure.
- natural gas typically contains hydrocarbons and CO 2 (about 0.5% to 5% mol). In order to avoid the freezing of the latter during liquefaction of natural gas, it should be removed.
- a means for removing CO 2 from the natural gas stream is, for example, an amine wash upstream of a liquefaction cycle.
- the amine wash separates the CO 2 from the feed gas by washing the stream of natural gas with a solution of amines in an absorption column.
- the amine solution enriched in CO 2 is recovered in the vat of this absorption column and is regenerated at low pressure in an amine distillation column (or stripping in English).
- This purification is performed by a dedicated CO 2 purification unit requiring the installation of a dedicated refrigeration cycle (typically a refrigeration system operating with ammonia for example).
- a dedicated refrigeration cycle typically a refrigeration system operating with ammonia for example.
- the function of the "cold group” refrigeration cycle is to provide the necessary cold for the CO 2 purification / liquefaction process.
- the condenser of the distillation column implemented in step 3 represents approximately 50% of the total cooling requirements.
- This cold can be provided via a dedicated refrigeration cycle (typically ammonia or propane) possibly coupled with a cooling system with water.
- the frigory production system represents a significant cost of the CO 2 purification and liquefaction unit and adds complexity of implementation to the site of implementation of the process, which represents a constraint.
- An existing solution consists in dissociating the two units (liquefaction of natural gas and purification of CO 2 ) which requires the establishment of two systems of production of frigories, one for the liquefaction unit of natural gas and one for the CO 2 purification unit.
- the inventors of the present invention have then developed a solution to solve the problem raised above, namely to minimize the investment in a system of production of frigories in the unit of purification / liquefaction of CO 2 and therefore d optimize investment spending while maintaining optimal efficiency for the liquefaction of natural gas in the liquefaction unit.
- thermal coupling means for producing frigories to ensure the thermal balance of the two units, typically refrigeration cycle compressor, and possibly a turbine / booster system in the case of nitrogen cycle.
- turbine / blower system means a turbine mechanically coupled (via a common shaft) to a single-stage compressor. The power generated through the turbine being directly transmitted to the single-stage compressor.
- This thermal integration is materialized by pooling any column, heat exchanger, unit or other suitable arrangement (typically a heat exchanger) where currents related to the liquefaction process of natural gas and currents related to the process of purification / liquefaction of CO 2 heat exchange.
- the method which is the subject of the present invention makes it possible to dispense with the cold group initially necessary for liquefying the CO 2 and for withdrawing the cold directly from the natural gas liquefier.
- This thermal integration thus makes it possible to dispense with equipment in the CO 2 purification unit.
- the proposed integration allows to provide cold at the three necessary temperature levels.
- the subject of the present invention is also a device for producing liquefied natural gas and liquefied CO 2 comprising a unit for treating a feed gas, producing at least one gas stream enriched in CO 2 and a stream of depleted natural gas. in CO 2 , and a unit for liquefying natural gas, said natural gas liquefaction unit comprising at least one main heat exchanger and a frigory production system, characterized in that the frigory production system is suitable for and designed to liquefy both the CO 2 enriched stream from the process unit and the CO 2 depleted natural gas stream flowing through the natural gas liquefaction unit, said natural gas liquefaction unit comprising at least one refrigeration cycle powered by a refrigerant flow from the main exchanger.
- the refrigeration requirement of a natural gas liquefaction unit is generally greater than the refrigeration requirement of a CO 2 purification / liquefaction unit, it is relevant to take advantage of the available capacity of the machines (compressors and / or turbine / superchargers) of the natural gas liquefaction unit to ensure all or at least partially the refrigeration requirement of the CO 2 purification / liquefaction unit and in particular to limit the investment in machinery of the purification / liquefaction unit of CO 2 .
- the incremental investment to increase the liquefaction capacity of a hydrocarbon liquefier is well below the incremental investment to increase the liquid production capacity of a CO 2 purification / liquefaction unit.
- 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 H 2 O, N 2 , CO 2 , H 2 S and other sulfur compounds, mercury and others.
- the feed stream containing the natural gas is thus pretreated before being introduced into the heat exchanger.
- This pre-treatment includes reducing and / or eliminating undesirable components such as CO 2 and H 2 S, or other steps such as pre-cooling and / or pressurizing. Since these measurements are well known to those skilled in the art, they are not further detailed here.
- natural gas refers to any composition containing hydrocarbons including at least methane. This includes a "raw” composition (prior to any treatment or wash), as well as any composition that has been partially, substantially, or wholly processed for the reduction and / or elimination of one or more compounds, including but not limited to limit, sulfur, carbon dioxide, water, mercury and some heavy and aromatic hydrocarbons.
- the heat exchanger may be any heat exchanger, unit or other arrangement adapted to allow the passage of a number of flows, and thus allow a direct or indirect heat exchange between one or more lines of refrigerant, and a or multiple feed streams.
- a natural gas feed stream 1 (flow rate considered 500,000 tons per year or about 60 tons per hour) containing CO 2 is introduced into a treatment unit 2 in which said stream 1 is separated into at least two gaseous streams 3 and 4.
- the natural gas feed stream 1 contains, for example, from 0.1 to 5 mol% of CO 2 .
- the first stream 3 is a stream of natural gas depleted in CO 2 .
- the second stream 4 is a stream enriched in CO 2 .
- the processing unit 2 is a unit that separates the CO 2 from the natural gas stream such as a chemical absorption unit, in particular a scrubbing unit amines (type MDEA, MEA, ...) that produces pure CO 2 (or concentrated) at low pressure (typically slightly higher than the pressure atmospheric).
- a chemical absorption unit in particular a scrubbing unit amines (type MDEA, MEA, ...) that produces pure CO 2 (or concentrated) at low pressure (typically slightly higher than the pressure atmospheric).
- pure CO 2 is meant a stream containing more than 95 mol% of CO 2 on a dry basis.
- the stream of natural gas 3 depleted in CO 2 is introduced into the atmosphere.
- main exchanger 8 of a natural gas liquefaction unit 5 to be liquefied.
- the pressure of this gaseous stream is for example between 25 and 60 bar absolute.
- the gas stream 3 contains between 30 ppm by volume and 500 ppm by volume of benzene, usually less than 100 ppm by volume.
- the gas stream 3 is cooled by heat exchange in the heat exchanger 8 in contact with a refrigerant.
- the heat exchanger 8 is supplied with at least one refrigerant stream 8.
- this stream may be composed of a mixed refrigerant stream or nitrogen that provides the cold necessary for the liquefaction of the natural gas stream.
- the refrigerant stream is sent to the high pressure exchanger (typically 30 to 60 bar) and returned at low pressure (1 to 10 bar).
- the recompression energy required for the operation of the refrigeration cycle is provided by a cycle compressor (possibly supplemented by a turbine / booster system as part of a nitrogen cycle)
- the natural gas stream 3 depleted in CO 2 introduced into the main exchanger 8 of a natural gas liquefaction unit 5 is for example liquefied according to the method described in the following lines.
- natural gas stream for example a washing column in which the heavy products are separated from the natural gas.
- heavy products is meant hydrocarbons having more than four carbon atoms and aromatic compounds including benzene.
- a gaseous stream no longer presenting a risk of freezing due to the presence of heavy hydrocarbons or aromatic derivatives (comprising typically less than 1 ppm by volume of benzene) is recovered to be introduced into a second section of the heat exchanger 8.
- By heat exchange it is cooled to the desired temperature (typically -160 ° C) to be sent to a means storage of liquefied natural gas 14.
- the combined refrigerant stream recovered at the outlet of the heat exchanger 8 is introduced into a phase separator pot producing a gas stream containing the light elements of the cooler at the top of the pot and a liquid stream 13 containing the heavy elements of the refrigerant in the tank. of pot.
- the cooling stream circulates in a closed cycle in the heat exchanger 8 to provide the cold necessary to liquefy said stream 3 of natural gas.
- the liquefaction cycle 9 uses a refrigerant that can be a mixture of refrigerants selected from typically nitrogen, methane, ethane, ethylene, propane, butane, pentane. It can be a cycle based on a refrigerant cycle consisting of a refrigerant or a mixture of several refrigerants.
- a refrigerant stream is introduced into the system 9 for producing frigories of the liquefaction unit 5 via a compressor (and possibly a via compressor / booster system).
- the second gaseous stream 4 enriched in CO 2 from the process unit 2 is compressed to intermediate pressure (typically 25 bar abs), cooled, purified (removal of all traces of H 2 O Hydrocarbons, particularly sulfur derivatives) and returned to a distillation column (stripping column) which separates the incondensables at the top of the concentrated liquid CO 2 recovered in the tank.
- intermediate pressure typically 25 bar abs
- purified removal of all traces of H 2 O Hydrocarbons, particularly sulfur derivatives
- a distillation column stripping column
- part of the liquid stream 13 containing the heavy elements of the refrigerant is extracted and circulated between the CO 2 purification / liquefaction unit 6 and the natural gas liquefaction unit 5.
- a refrigerant cycle dedicated to the CO 2 purification / liquefaction unit 6 is avoided by increasing the power of the cycle dedicated to the liquefaction of the natural gas (typically of the order of 5%).
