Description
Technical field
The invention belongs to the petrochemical technology field, relate to oil-refining chemical technology and equipment thereof, particularly the heavy oil catalytic cracking process riser exports efficiently separating fast of terminal catalyst and oil gas.
Background technology
Along with the exploitation utilization of catalytic cracking high-performance molecular sieve catalyst, the riser reaction technology has become the core technology of catalytic cracking industry.For adapting to its development need, the also continuous development and update of the quick isolation technics of gas-solid that riser is terminal.Terminal its main purpose of fast gas-solid separation device of riser is to prevent to react back oil gas to continue to take place unnecessary overcracking, reduces the light oil productive rate, also reduces the coking in the settler simultaneously, the safe operation of assurance device long period as far as possible.So; Fast branch technology must reach " three is fast " and require: gas-solid rapidly and efficiently separates (separative efficiency generally is equal to or greater than 99%); Oil gas is drawn settler (mean residence time was less than 5 seconds) fast, the in time efficient stripping of catalyst (as far as possible reducing H/C ratio on the spent agent).At present, the riser that adopts in the industry exports terminal fast gas-solid separator and mainly contains two types: inertial separator and centrifugal separating device.
Inertial separator is mainly used in the wax catalysis cracking period before the eighties, and typical form has inverted L shape, T type, trilobal cross etc.It separates mainly realizes by 180 ° of gas-solids that produced, the two phase inertia differences that swerve behind the gas-solid mixture outflow riser.Because turning path is very short, the separation between the gas-solid mixture is very insufficient; The catalyst granules that the oil gas rising is carried secretly is more, and separative efficiency has only 70～80%, and follow-up cyclone separator generally must could guarantee that the solids content in the slurry oil is unlikely to higher by two-stage series connection.Oil gas after the separation slowly rises in the settler large space, and general about 20 seconds ability get into the cyclone separator (being called for short the top revolves) on settler top, in cyclone separator, need 3～4 seconds ability to get into fractionating system again.Under hot conditions, the reacted oil gas time of staying is oversize like this, causes oil gas generation overcracking, increases the productive rate of dry gas and coke, and the purpose product yield is descended.Under wax catalysis cracking situation, this problem is not outstanding, but under the processing heavy oil condition, this contradiction is very sharp-pointed.
The strong centrifugal force field that centrifugal separating device mainly relies on the gas-solid two-phase mixture rotation to form realizes that gas-solid separates fast, and using at present is cyclone separator and the fast subsystem of spiral-flow type more widely.Cyclone separator (slightly revolving) has the high advantage of gas solid separation efficient, and separative efficiency can reach more than 98%.Its shortcoming is after the oil gas after separating is discharged from riser, pass through bigger settler space and could get in the top cyclone separator (revolve on the top), and gas residence time reached more than 15 seconds.At high temperature still there is the overcracking problem, influences yield of light oil, cause the coking in the settler simultaneously, influence the long period safe handling of device.
For solving the not high problem of inertial separator separative efficiency, U.S. Pat 4,495; The ejection type fast gas-solid separator has been developed in 063 (1985), and its gas solid separation efficient can reach 90～95%, and the gas backmixing rate is reduced to about 20%; But pressure drop is up to thousands of handkerchiefs; Operating flexibility is less, and the difficulty that goes into operation is not applied.For further improving the operating characteristics of inertial separator, improve its separative efficiency, shorten the time of staying of oil gas in settler; U.S. Pat 4; 364,965 (nineteen eighty-twos), 4,721; 603 (1988) have proposed the improvement project of band seal bootr, but do not resolve the drawback of oil gas overstand in the decanting zone.
For solving the problem that centrifugal separating device exists, U.S. Pat 4,502,947 (1985), US4; 579,716 (1986), US 4,624; Enclosed direct connection cyclone separation system has been developed in 772 (1986) etc., will slightly revolve riser directly to link to each other with settler top cyclone inlet, has shortened the time of staying of oil gas in settler greatly; Make the back-mixing rate of gas further drop to 6%～10%, but the poor-performing of the compressive resistance of this device fluctuation is wanted SC when going into operation.Subsequently; U.S. Pat 5,158,669 (1992), European patent EP 0593827A1; Chinese patent CN92112441 (1992) etc. have directly connected a stripping section in the portion of screwing off slightly again; Change a part of reaction oil gas from the rough sledding that thick spin material leg sprays downwards, further shortened the mean residence time of reaction oil gas in settler, oil gas back-mixing rate is further dropped to below 2%.Clear 61-25413 of japanese communique (B2) (1986) and U.S. Pat 4; 482; The circular arc bend pipe that several downward-sloping certain angles have then been adopted at the riser end in 451 (1984) is as the gas-solid quick disconnector, and added a seal bootr to realize drawing fast of oil gas in its outside.U.S. Pat 5; In 314,611 (1994), a kind of arm-type fast gas-solid separator of eddy flow that has seal bootr has been proposed; Efficient separate fast and oil gas is drawn fast that can realize catalyst; But this patent does not specify the concrete structure of this device, and the oil gas detention space outside the seal bootr is still too big, is prone to cause coking.
In recent years; Domestic Chinese Petroleum Univ. has developed a series of advanced persons' fast branch technology, and FSC system (Chinese patent ZL96103419.X), VQS system (Chinese patent ZL96103478.5, ZL96103420.3, ZL01228805.5) and CSC system (Chinese patent ZL98102166.2, ZL98204681.2) are more typically arranged.The FSC system has adopted slightly revolves the riser export structure that combines with the preparatory stripper that adds ring baffle.Because adding ring baffle in the stripper in advance, Stripping effect has bigger improvement than the VDS system of UOP.The CSC system has adopted slightly revolves or riser export structure that vortex quick separation combines with the preparatory stripper that adds close-phase circulation.Because adopted the preparatory gas stripping process of close-phase circulation, Stripping effect has had further raising again than FSC system, and structure is also very simple.The main distinction of the VSS system of VQS system and UOP is the improvement at eddy flow header structure and lower annular baffle arrangement.Yet the shortcoming that the fast subset of spiral-flow types such as VSS system and VQS system exists is that its gas solid separation efficient generally is no more than 98.5%.For this reason; Chinese patent ZL02159407.4 and Chinese patent ZL02159408.2 have proposed a kind of riser gas-solid vortex quick separation equipment that has the shunting tube; The shunting tube is positioned at the outlet position of riser and exports the position coaxial arrangement with riser in this device; Can realize drawing fast of quick separation of efficient gas-solid and gas, make the eddy flow head realize the separative efficiency of gas-solid more than 99%.Chinese patent (publication number CN1363410A) has proposed a kind of plural serial stage compact gas-solid of riser fluidized reaction system separation and sedimenting system fast of being used for; Be used to react back oil gas and separating fast of catalyst and drawing fast of oil gas; The mean residence time of oil gas in settler can be reduced to 3～4 seconds; Distribute thereby improve product, eliminate the coking phenomenon in the settler.Yet; This patent does not spell out concrete structure and the embodiment that secondary segregation section is adopted; And the catalyst granules content that in this system, is mingled with in the oil gas owing to entering secondary segregation section is lower; There is big difficulty in its particle diameter more trickle than in the one-level segregation section to the separation of this part catalyst granules, and the separative efficiency of secondary segregation section is difficult to guarantee.
