Definitions
- the present invention relates to a compression installation of a gaseous flow comprising at least 0.1% water, typically at least 0.1% water and at least 20% CO 2 , and a process compression implementing such an installation.
- C0 2 capture processes generated in a given process are developed. It involves extracting C0 2 from a gas generated by the process, possibly purifying it and finally, in general, compressing it in order to transport it in a pipeline.
- One of the ways of treating C0 2 is to distill the C0 2 rich gas stream in a cryogenic purification unit.
- the input gas being fumes from a process such as an adsorption purification process or a blast furnace process.
- the document FR-A-1412608 teaches a compressed gas intermediate cooling installation comprising compressors associated with exchangers and a cooling water circuit. The consecutive heat exchangers are connected in series to the cooling water circuit. Similar teaching is given by WO-A-2011/088527, US-A-2011/000227 and US-A-7,269,956.
- a problem that arises is to provide a feed installation of a cryogenic distillation column having a lower cost.
- a solution of the invention is a gaseous stream compression installation comprising at least 0.1% by volume of water, comprising a compressor with N stages of compression, in which: each compression stage comprises a compression means and an exchanger connected directly or indirectly to a cooling water circuit C; and
- the exchangers not connected in series to the cooling water circuit comprise at their cooling water outlet a device for creating a pressure drop.
- the installation according to the invention may have one or more of the following characteristics:
- the casings of the exchangers of the first n compression stages, situated on the supply side of the compressor, consist of a steel whose chromium content is less than 11% by mass and without a stainless coating, with n ⁇ N - 1;
- the casings of the exchangers of the first n compression stages, situated on the compressor supply side, are made of carbon steel, with n ⁇ N - 1.
- the second exchanger IC3 is also connected directly to the cooling water circuit C and a temperature control system makes it possible to control the mixing of the cooling water coming from the first exchanger and the cooling water coming directly from the cooling water circuit C (see Figure 4).
- the exchangers not connected in series with the cooling water circuit comprise at their cooling water outlet a device making it possible to create a pressure drop corresponding to the pressure drop caused by the series connection of the heat exchangers;
- the exchanger of the last compression stage, located on the production side of the compressor, is made of stainless steel.
- n N-1 is preferably used.
- the device for creating a pressure drop comprises an orifice or a valve, typically a pressure drop of the order of 1 bar (or more if necessary).
- the feed system feeds gas stream, a cryogenic distillation column.
- the present invention also relates to a method of compressing a gas stream comprising at least 0.1% water and at least 20% C0 2 implementing a compression installation according to the invention.
- the compression method according to the invention is characterized in that: the temperature of the cooling water Te of the cooling circuit is measured;
- the cooling water inlet of said exchanger is connected to the cooling water outlet of a first exchanger IC2 belonging to said N-1 compression stages, located on the supply side of the compressor, and / or
- the gas stream is a stream produced by a PSA (pressure swing adsorption) H 2 , a PSA C0 2 , a membrane separation process, a combustion turbine, an oxy-combustion process, a process for the manufacture of cement, a blast furnace, a process for manufacturing hydrogen or a refining process.
- a PSA pressure swing adsorption
- the solution proposed by the present invention makes it possible to reduce the price of the machine by avoiding the condensation of wet C0 2 (that is to say comprising at least 0.1% of water) in the compressor making it possible to choose materials much cheaper, typically carbon steel.
- composition of the gas stream to be compressed is not constant and varies as a function of the operating phases of the PSA or the blast furnace, which modifies the value of the dew point.
- Figure 1 gives an example of composition of a gas stream from a PSA production phase.
- Figure 2 gives the dew curves for the different gas flow temperatures.
- the minimum temperature of the gases in an exchanger is considered equal to the cooling water inlet temperature, corresponding to the skin temperature of the exchanger tubes in which the cooling water circulates.
- the minimum temperature of the gas stream in the exchanger can be controlled via the cooling water inlet temperature.
- a margin can be constantly maintained between the conditions of the gas stream and its dew point.
- the installation according to the invention is used.
- the invention will now be detailed by taking the example of a compression installation comprising 4 compression stages (see FIG. 3) supplying a cryogenic distillation column in compressed gas flow.
- the exchangers IC2 and IC3 of the second and third compression stages are connected in series ( Figure 3).
- the exchanger IC3 of the third compression stage will be according to the invention named "second exchanger”, while the exchanger IC2 of the second compression stage will be according to the invention named "first exchanger”.
- the exchanger of the third compression stage is fed by the return of hot water (cooling water heated in the exchanger of the second compression stage) coming from the exchanger of the second compression stage thus allowing a sufficient margin at the dew point in the exchanger of the third compression stage and thus avoiding the risk of condensation.
- the difference in water temperature between the inlet and the outlet of the exchanger is generally 10 ° C.
- the IC2 and IC3 heat exchangers of the second and third compression stages must be designed for the same cooling water flow rate.
- a device (an orifice or a valve for example) must be installed at the exit of the ICI exchangers and cooler of the first and the fourth compression stage to create an additional pressure drop (typically 1 bar) corresponding to the pressure drop induced by the series assembly of exchangers IC2 and IC3 of the second and third compression stages.
- Means for measuring the temperature, the pressure and the water content of the gas stream and the temperature of the water of the cooling circuit at the inlet of the exchanger of the third compression stage can be put in place to calculate the difference between the temperature of the gas stream and its dew point.
- the first exchanger or exchangers of the first compression stages located on the supply side of the compressor do not need to receive hot water and are connected directly to the cooling water circuit.
- the gas stream being at lower pressure, its dew point is colder and therefore further from the nominal temperature of the cooling water.
- the invention proposes to circulate the cooling water at least partially in series in at least two exchangers
- the scrolls of the compressor are made of carbon steel as for standard compressors.
- the wheels are made of martensitic stainless steel material such as standard compressors. The exact grade is selected to meet the ⁇ 617 (US Code for Machinery) requirement for hydrogen gas applications.
- the exchangers of the first three compression stages are preferably shell type heat exchangers. Their envelopes are made of carbon steel as standard.
- the tubes are usually made of a copper-based material.
- the tubes are made of carbon steel.
- stainless steel or copper tubes are required to prevent corrosion on the water side.
- the tubular plate is made of forged carbon steel.
- a resistance weld of the tube / tube plate connection is recommended. These welds are then tested by a helium leak test with an acceptance criterion based on low leakage rate.
- a "break-speed" plate is added. All other gas side parts of the exchanger are carbon steel. These can be galvanized.
- Drains are installed at a low point in case of condensation (in case of rupture of the tube for example).
- a level detector in these low points makes it possible to detect the presence of liquid in the exchanger.
- a water separator is installed on the outlet of each exchanger to avoid any drop to go to the wheel in case of condensation (in case of rupture of the tube for example).
- Automatic condensate traps are not necessary. Only manual valves are installed in the drain when the liquid is detected.
- a temperature sensor in the floor suction hoses detects condensation and stops the machine.
- the Fourth Stage Compression Heat Exchanger (Cooler) is made entirely of stainless steel (the 304L grade is a good compromise) because it is highly condensed.
- a water separator and an automatic condensate trap are used to remove condensed (high carbon dioxide) water from the gas. These devices must be adapted to carbonic acid
- the present invention also relates to a method for starting the compression installation according to the invention, in which:
- a dry gas at a temperature Tg greater than the dew point temperature Tr of the gas stream to be compressed is compressed in the compressor with N compression stages until the skin temperature of the first n compression means and the first n heat exchanger in contact with the gas flow, located on the compressor supply side with n ⁇ N - 1, and the water temperature of the cooling water circuit C are greater than the dew point temperature Tr of the gas stream to be compressed,
- the gas stream comprises at least 0.1% water and at least 20% CO 2 , and the dry gas is nitrogen or carbon dioxide.
- This start-up procedure makes it possible to heat the parts of the compressor (volutes, pipes, exchangers, etc.) in contact with the gas flow in order to avoid the condensation of C0 2 and thus the corrosion of these parts.
- the cooling water may be too cold and could induce condensation in the exchangers.
- the nitrogen start phase also makes it possible to heat the temperature of the cooling water to a sufficient level.
- the temperature of the cooling water is monitored and enters the conditions necessary to replace the nitrogen with the process gas and also to control and optimize the cooling capacity of the water system (on / off cooling system fans ).
- the power of the cooling water of the cooling fan is reduced when the water is too cold compared to the level of the water content in the process gas.
- the subject of the present invention is also a process for stopping the feed installation according to the invention, in which the compressor is swept and purged with a dry gas.
