- US 4808197 discloses a combination diptube and quench ring, which is communicated with a pressurized source of a liquid coolant such as water and which directs a flow thereof against the diptube guide surfaces to maintain such surfaces in a wetted condition.
- US 5976203 describes a synthesis gas generator with combustion and quench chambers for generating, cooling and cleaning gases that are generated by partial oxidation, such generator including quench nozzles for spraying a quenching medium in a finely distributed form into the useful gas stream.
- the described generator further includes a cone arranged at the outlet of the quench chamber, extending into the water bath chamber gas space.
- WO 2008/065184 describes a vessel for cooling syngas wherein the wall of the reaction chamber is made of an arrangement of interconnected parallel arranged tubes resulting in a substantially gas-tight wall.
- the described vessel further contains a diptube that is partially submerged in a water bath.
- Preferably at the upper end of the diptube injecting means are present to add a quenching medium to the, in use, downwardly flowing hot product gas.

- the ratio between the larger diameter and the smaller diameter is between 1.25:1 and 2:1 .
- Syngas has the meaning of a mixture comprising carbon monoxide and hydrogen.
- the syngas is preferably prepared by gasification of an ash comprising carbonaceous feedstock, such as for example coal, petroleum coke, biomass and deasphalted tar sands residues.
- the coal may be lignite, bituminous coal, sub-bituminous coal, anthracite coal and brown coal.
- the syngas as present in the syngas collection chamber may have a temperature ranging from 600 to 1500 °C and have a pressure of between 2 and 10 MPa.
- the syngas is preferably cooled, in the vessel according the present invention, to below a temperature, which is 50 °C higher than the saturation temperature of the gas composition. More preferably the syngas is cooled to below a temperature, which is 20 °C higher than the saturation temperature of the gas composition.
- FIG. 1 shows a vessel 1 comprising a syngas collection chamber 2 and a quench chamber 3. In use it is vertically oriented as shown in the Figure. References to vertical, horizontal, top, bottom, lower and upper relate to this orientation. Said terms are used to help better understand the invention but are by no means intended to limit the scope of the claims to a vessel having said orientation.
- the syngas collection chamber 2 has a syngas outlet 4, which is fluidly connected with the quench chamber 3 via a tubular diptube 5.
- the syngas collection chamber 2 and the diptube 5 have a smaller diameter than the vessel 1 resulting in an upper annular space 2a between said chamber 2 the wall of vessel 1 and a lower annular space 2b between the diptube 5 and the wall of vessel 1.
- Annular space 2a and 2b are preferably gas tight separated by sealing 2c to avoid ingress of ash particles from space 2b into space 2a.
- the syngas outlet 4 comprises of a tubular part 6 having a diameter, which is smaller than the diameter of the tubular diptube 5.
- the tubular part 6 is oriented co-axial with the diptube 5 as shown in the Figure.
- the vessel 1 as shown in Figure 1 is at its upper end provided with a syngas inlet 7 and a connecting duct 8 provided with a passage 10 for syngas.
- the passage for syngas is defined by walls 9.
- Connecting duct 8 is preferably connected to a gasification reactor as described in more detail in WO-A-2007125046 .
- the diptube 5 is open to the interior of the vessel 1 at its lower end 10. This lower end 10 is located away from the syngas collection chamber 2 and in fluid communication with a gas outlet 11 as present in the vessel wall 12.
- the diptube is partly submerged in a water bath 13.
- a draft tube 14 is present to direct the syngas upwardly in the annular space 16 formed between draft tube 14 and diptube 5.
- deflector plate 16a is present to provide a rough separation between entrained water droplets and the quenched syngas.
- Deflector plate 16a preferably extends from the outer wall of the diptube 5.
- the lower part 5b of the diptube 5 has a smaller diameter than the upper part 5a as shown in Figure 1 .
- the quench zone 3 is further provided with an outlet 15 for water containing for example fly-ash.
- the tubular part 6 is preferably formed by an arrangement of interconnected parallel arranged tubes resulting in a substantially gas-tight tubular wall running from a cooling water distributor to a header.
- the cooling of tubular part 6 can be performed by either sub-cooled water or boiling water.
- the walls of the syngas collection chamber 2 preferably comprises of an arrangement of interconnected parallel arranged tubes resulting in a substantially gas-tight wall running from a distributor to a header, said distributor provided with a cooling water supply conduit and said header provided with a discharge conduit for water or steam.
- the walls of the diptube are preferably of a simpler design, like for example a metal plate wall.
- Discharge conduit 19 At the end of the diptube 5 which is nearest to the syngas collection chamber 2 a discharge conduit 19 is present having an outflow opening for liquid water directed such that, in use, a film of water is achieved along the inner wall of the diptube. Discharge conduit 19 is connected to water supply conduit 17. Discharge conduit 19 will be described in detail by means of Figures 2 and 3 .
- Figure 1 also shows water spray nozzles 18 located in the diptube 5 to spray droplets of water into the syngas as it flows downwardly through the diptube 5.
- the nozzles 18 are sufficiently spaced away in a vertical direction from the discharge conduit 19 to ensure that any non-evaporated water droplets as sprayed into the flow of syngas will contact a wetted wall of the diptube 5. Applicants have found that if such droplets would hit a non-wetted wall ash may deposit, thereby forming a very difficult to remove layer of fouling.
- the nozzles 18 are positioned in the larger diameter part 5a of the dipleg 5. More residence time is achieved by the larger diameter resulting in that the water as injected has sufficient time to evaporate.
- Figure 2 shows detail A of Figure 1 .
- FIG. 2 shows that the tubular part 6 terminates at a point within the space enclosed by the diptube 5 such that an annular space 20 is formed between the tubular part 6 and the diptube 5.
- a discharge conduit 19 for a liquid water is present having a discharge opening 21 located such to direct the liquid water 22 along the inner wall of the diptube 5.
- Conduit 19 and tubular part 6 are preferably not fixed to each other and more preferably horizontally spaced away from each other. This is advantageous because this allows both parts to move relative to each other. This avoids, when the vessel is used, thermal stress as both parts will typically have a different thermal expansion.
- the gap 19a as formed between conduit 19 and part 6 will allow gas to flow from the syngas collection chamber 2 to the space 2a between the wall of the chamber 2 and the wall of vessel 1. This is advantageous because it results in pressure equalization between said two spaces.
- the discharge conduit 19 preferably runs in a closed circle along the periphery of the tubular part 6 and has a slit like opening 21 as the discharge opening located at the point where the discharge conduit 19 and the inner wall of the diptube 5 meet. In use, liquid water 22 will then be discharged along the entire inner circumference of the wall of the diptube 5. As shown conduit 19 does not have discharge openings to direct water into the flow of syngas, which is discharged via syngas outlet 4.
- FIG 2 also shows that the discharge conduit 19 is suitably fluidly connected to a circular supply conduit 23.
- Said supply conduit 23 runs along the periphery of the discharge conduit 19.
- Both conduits 19 and 23 are fluidly connected by numerous openings 24 along said periphery.
- the discharge conduit 19 is directly fluidly connected to one or more supply lines 17 for liquid water under an angle with the radius of the closed circle, such that in use a flow of liquid water results in the supply conduit.
- the discharge conduit 19 or conduit 23 are connected to a vent.
- This vent is intended to remove gas, which may accumulate in said conduits.
- the ventline is preferably routed internally in the vessel 1 through the sealing 2c to be fluidly connected to annular space 2b.
- the lower pressure in said space 2b forms the driving force for the vent.
- the size of the vent line for example by sizing an orifice in said ventline, is chosen such that a minimum required flow is allowed, possibly also carrying a small amount of water together with the vented gas into the annular space 2b.
- conduit 19 is provided with a vent as shown in Figure 2 , wherein the discharge conduit 19 has an extending part 26 located away from the discharge opening 21, which extending part 26 is fluidly connected to a vent conduit 27.
- the circular supply conduit 23 of Figure 3 is suitably fluidly connected to one or more supply lines 17 for liquid water under an angle ⁇ , such that in use a flow of liquid water results in the supply conduit 23.
- Angle ⁇ is preferably between 0 and 45°, more preferably between 0 and 15°.
- the number of supply lines 17 may be at least 2. The maximum number will depend on the dimensions of for example the conduit 23.
- the separate supply lines 17 may be combined upstream and within the vessel 1 to limit the number of openings in the wall of vessel 1.
- the discharge end of supply line 17 is preferably provided with a nozzle to increase the velocity of the liquid water as it enters the supply conduit 23. This will increase the speed and turbulence of the water as it flows in conduit 23, thereby avoiding solids to accumulate and form deposits.
- the nozzle itself may an easy to replace part having a smaller outflow diameter than the diameter of the supply line 17.
- the openings 24 preferably have an orientation under and angle ⁇ with the radius 25 of the closed circle, such that in use a flow of liquid water results in the discharge conduit 19 having the same direction has the flow in the supply conduit 23.
- Angle ⁇ is preferably between 45 and 90°.
- Figure 3 also shows tubular part 6 as an arrangement of interconnected parallel arranged tubes 28 resulting in a substantially gas-tight tubular wall 29.
- Figure 4 shows a vessel 30 according to the invention wherein the syngas collection chamber 2 is a reaction chamber 31 provided with 4 horizontally firing burners 32.
- the number of burners may suitably be from 1 to 8 burners.
- the wall 33 of the reaction chamber 31 is preferably an arrangement of interconnected parallel arranged tubes 34 resulting in a substantially gas-tight tubular wall. Only part of the tubes are drawn in Figure 4 .
- the tubes 34 run from a lower arranged cooling water distributor 37 to a higher arranged header 38.
- the burners 32 are arranged in Figure 4 as described in for example WO-A-2008110592 , which publication is incorporated by reference.
- the burners or burner may alternatively be directed downwardly as for example described in WO-A-2008065184 or in US-A-2007079554 .
- a layer of liquid slag will be present on the interior of wall 33. This slag will flow downwards and will be discharged from the reactor via outlet 15.
- the syngas outlet 4 consists of a frusto-conical part 35 starting from the lower end of the tubular wall 33 and diverging to an opening 36.
- part 35 has a tubular part 35a connected to the outlet opening of said part 35 to guide slag downwards into the diptube 5. This is advantageous because one then avoids slag particles to foul the discharge conduit 19. If such a tubular part 35a would not be present small slag particles may be carried to the conduit 19 by recirculating gas. By having a tubular part of sufficient length such recirculation in the region of conduit 19 is avoided.
- the length of 35a is such that the lower end terminates at or below the discharge conduit 19. Even more preferably the lower end terminates below the discharge conduit 19, wherein at least half of the vertical length of the tubular part 35a extends below discharge conduit 19.
- the frusto-conical part 35 and the optional tubular part 35a and 35b comprise one or more conduits, through which in use boiling cooling water or sub-cooled cooling water, flows.
- the design of the conduits of parts 35, 35a and 35b may vary and may be for example spirally formed, parallel formed, comprising multiple U-turns or combinations.
- the part 35, 35a and 35b may even have separate cooling water supply and discharge systems.
- Preferably the temperature of the used cooling water or steam make of these parts 35 and 35a are measured to predict the thickness of the local slag layer on these parts.
- the invention is thus also directed to a process to avoid slag blockage at the outlet of the reaction chamber in a reactor as described by Figure 4 by measuring the temperature of the cooling water or the steam make of these parts 35 and 35a in order to predict when a slag blockage could occur and adjust the process conditions to avoid such a blockage.
- a decrease in temperature of the used cooling water or a decrease in steam make are indicative for a growing layer of slag.
- the process is typically adjusted by increasing the gasification temperature in the reaction chamber such that the slag will become more fluid and consequently a reduction in thickness of the slag layer on parts 35 and 35a will result.
- the supply and discharge conduits for this cooling water are not shown in Figure 4 .
- the frusto-conical part 35 is connected to the tubular part 6 near its lower end. Opening 36 has a smaller diameter than the diameter of the tubular part 6 such that liquid slag will less easily hit the wall of the tubular part 6 and or of the diptube 5 when it drops down into the water bath 13 and solidifies. In water bath 13 the solidified slag particles are guided by means of an inverted frusto-conical part 39 to outlet 15.
- FIG 4a a preferred embodiment for tubular part 35a is shown, wherein the lower end of tubular part 35a is fixed by a plane 35b extending to the lower end of the next tubular part 6.
- This design is advantageous because less stagnant zones are present where solid ash particles can accumulate.
