Definitions
- the present invention relates to the field of catalyst regeneration, and more particularly to a continuous catalyst regeneration device and the regeneration method using this device.
- Burning is in the prior art often carried out in a radial bed of thin thickness arranged in a ring in which the catalyst flows from top to bottom by gravity at low speed and where the flue gas circulates radially through the bed, often the outside of the bed inwards.
- a regeneration gas circuit is installed, including various equipment including a recycle compressor and often a dryer.
- the present invention therefore aims to overcome one or more of the disadvantages of the prior art by providing a regenerator of a new model, and the associated method, to reduce the size of the equipment used for the same amount of regenerated catalyst.
- the present invention provides a continuous catalyst regeneration device comprising at least one combustion zone formed by at least one annular combustion zone, centered along a longitudinal axis, in which the catalyst circulates, a conduit for combustion. catalyst inlet and a catalyst outlet pipe, a circulation zone of an external oxidizing gas disposed around the annular combustion zone and an internal circulation zone disposed inside the annular combustion zone, in which the burning zone is divided into sectors by hermetic longitudinal plates arranged radially with respect to the longitudinal axis of the regenerator.
- the sector number is between 3 and 12.
- each sector is in communication with the next sector by a connecting pipe in which the oxidizing gas circulates.
- each sector is supplied with oxygen by an oxygen conduit opening into the connecting conduit.
- the regeneration device comprises a gas supply duct oxidant opening in the annular zone of external circulation of the first sector and a combustion gas evacuation pipe leaving d ⁇ the annular zone of internal circulation of the last sector.
- the regeneration device comprises a supply duct of the oxidizing gas opening into the annular zone of internal circulation of the first sector and a pipe for discharging the oxidizing gas leaving the annular zone of external circulation of the last sector.
- the first burning zone comprises a third annular circulation zone disposed inside the annular zone of internal circulation allowing the circulation of the oxidizing gas between the annular zone of internal circulation of the second burning zone of a first sector and the annular zone of external circulation of the first burning zone of a second sector.
- the regeneration device comprises a secondary oxygen duct opening between the two burning zones and allowing an additional supply of oxygen.
- the burning zone comprises an upper screen and a lower screen preventing the oxidizing gas from circulating directly from the supply duct to the exhaust duct without passing through the catalyst.
- the invention also relates to a catalyst regeneration method in which the catalyst descends by gravity in an annular combustion zone divided into sectors, and wherein the oxidizing gas crosses each sector successively, the oxidizing gas being cooled and recharged with oxygen between each sector.
- the oxidizing gas passes through the annular combustion zone from outside to inside.
- the catalyst is a catalytic reforming catalyst.
- the temperature of the first annular combustion zone is between 400 ° C. and 550 ° C. and the temperature of the second annular combustion zone is at a temperature at least 10 ° C. C and at most 40 ° C relative to that of the first annular combustion zone.
- FIGs 1 and 2 illustrate a catalyst regeneration apparatus or regenerator according to the prior art.
- the apparatus shown here is cylindrical along a longitudinal axis (A). It consists of an annular combustion zone (3), centered on the longitudinal axis of the regenerator, in which the coke is burned. This annular combustion zone (3) is fed with catalyst via catalyst descent inlet ducts (4).
- the regenerator also comprises an annular zone of external circulation (11) of the oxidizing gas surrounding the annular combustion zone (3) and an annular zone of internal circulation (15) inside the annular combustion zone (3). It is this set of annular zones of combustion (3) and external circulation (11) and internal (15) which forms the burning zone of the regenerator.
- the catalyst is fed through inlet ducts (4) and then passes through the annular combustion zone (3) and is evacuated by outlet ducts (4 ') of catalyst descent.
- the oxidizing mixture forming the oxidizing gas (13) composed of a small proportion of oxygen diluted in a nitrogen / carbon dioxide mixture, arrives in the annular combustion zone (3) via a feed duct (1).
- An upper screen (5, 5 ') forces the combustion gas (13) which arrives via the supply duct (1) to circulate in the annular circulation zone (11) outside and then to pass through the catalyst which is in the zone annular combustion (3), before going down through the center (15) of the regenerator- located inside the annular combustion zone (3).
- the oxidizing gas thus circulates radially through the catalyst.
- the oxidizing gas (13) then passes between the catalyst outlet ducts (4 ') and is discharged through the lower discharge duct (2) of the burning zone.
- a lower screen (6) prevents the direct communication between the inlet and the outlet of the burning zone, and thus prevents the gas (13) from passing directly from the supply duct (1) to the exhaust duct (2) without passing through the catalyst.
- the device according to the invention consists of sectors (14). These sectors are formed by hermetic longitudinal plates (10) formed of the same material as the annular zone, arranged radially, that is to say along the spokes of the regenerator.
- the first sector is defined as the sector in which the regenerator feeds with oxidizing gas (13).
- the other sectors are named second sector, third sector up to the last sector, respecting the circulation order of the oxidant gas (13) in the regenerator.
- the sectors illustrated in FIGS. 3 to 8 are of identical sizes, but in certain cases it may be necessary for certain sectors to be of different sizes.
- the oxidizing gas (13) supplies via the supply duct (1) an annular zone of external circulation (11) of the first sector (14) (visible in FIG. 4), then passes through the catalyst in the annular combustion zone (3).
- the combustion gas (13) then rises to the top of the burning zone by an internal circulation zone (15), disposed inside the annular combustion zone (3), to be brought into the annular circulation zone.
- external (11) of a second sector (14 ') (visible on the 4) by a connecting conduit (7).
- the oxygen necessary for the burning of the coke in the second sector (14 ') is fed through an oxygen conduit (8) into the connecting pipe (7).
- This connecting pipe (7) which allows the oxidizing gas (13) to circulate from one sector (14) to the other (14 ').
- the oxygen used is diluted beforehand with a cold gas, which also allows the gas to cool at the entrance of the second sector (14 "), and the gas then circulates in all sectors (14) of the burning zone in the same way. to the last sector (14 ") and is then evacuated through the exhaust duct (2).
- the combustion gas (13) circulates, for each sector, from outside to inside the cylinder forming the regenerator.
- the oxidizing gas (13) used is composed of a small proportion of oxygen diluted in a nitrogen / carbon dioxide mixture.
- the amount of oxygen is between 0.2 and 0.8% (close to 0.5%).
- the system operates at a pressure of between 2 and 10 bar, preferably between 4 and 7 effective bars.
- An alternative (not shown) of this device is to circulate the oxidant gas (13) from the inside to the outside of the regenerator.
- the supply duct (1) opens into the annular zone of internal circulation (15) and the connecting duct (7) then connects the annular zone of external circulation (11) of a first sector (14) with the annular zone of internal circulation (15) of the next sector (14 ').
- the oxidant gas exits via the pipe (2), is successively cooled in the heat exchanger (34) by exchange with the inlet gas, and then passes through a pipe (341) in the air cooler (36), and is mixed with the liquid from a line (380) of the pump (38) before entering through the line (360) into the separator balloon (37).
- This balloon also serves to neutralize the flue gas which contains chlorine, by means of an injection of soda (not shown).
- the condensed water mixed with sodium hydroxide is withdrawn via the pipe (370) and used for washing and neutralize the condensation zones to avoid corrosion. The rest of the water is purged (line not shown).
- regenerator illustrated in FIGS. 4 and 6 is used, ie an 8-sector regenerator and 2 burn zones.
- the amount of oxidizing gas used with the device according to the invention corresponds to 30% of the amount of oxidizing gas used with a device according to the invention.
- the energy balance also corresponds to 30% of the consumption of a device of the prior art.
