- 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 0 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 0 C higher than the saturation temperature of the gas composition. More preferably the syngas is cooled to below a temperature, which is 20 0 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 coaxial 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 is preferably 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 preferred 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 preferably 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 CC, such that in use a flow of liquid water results in the supply conduit 23.
- Angle OC 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 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. This is especially advantageous if the gasification process is run at temperatures, which would be beneficial for creating a sufficiently thick slag layer for a specific feedstock, such as low ash containing feedstocks like certain biomass feeds and tar sand residues. Or in situations where a coal feedstock comprises components that have a high melting point. The danger of such an operations is that outlet 4 may be blocked by accumulating slag. By measuring the temperature of the cooling water or the steam make one can predict when such a slag accumulation occurs and adjust the process conditions to avoid such a blockage.
- 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.
- 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.
