Description
Technical field
This utility model belongs to technical field of petrochemical industry, particularly relates to a kind of new alkylation reaction unit.
Background technology
At present, in alkylated reaction production process, circulate cryogen after water cooler is cooled to 35 DEG C to cryogen buffering
In tank, separating gas-liquid two-phase subsequently into flash distillation side in flash tank, liquid phase is with being pumped to after response system mixes with raw material to instead
Answering device, owing to circulation refrigerant temperature is at 35 DEG C, the circulation cryogen after flash distillation is at-6 DEG C at this temperature, causes alkylated reaction
Temperature drift, affects quality and the acid consumption of alkylation products.
Summary of the invention
The purpose of this utility model is to provide one can reduce alkylated reaction temperature and acid consumption, improves alkylation and produces
The new alkylation reaction unit of quality.
The technical solution of the utility model is:
New alkylation reaction unit, including reactor, acid settler, flash tank, the first compressor, separatory tank, second
Compressor, water cooler, surge tank, said apparatus is connected by pipeline, and pipeline arranges valve and pump, described surge tank and flash distillation
Lithium bromide absorption chiller system is set between tank.
Described lithium bromide absorption chiller system includes heat exchanger, desalination water pot, lithium bromide refrigerator, heat exchanger connection surge tank and
Flash tank, heat exchanger, desalination water pot, BrLi chiller become blood circulation.
Described lithium bromide refrigerator includes suction tube, and the tube wall of suction tube has solution suction passage.
The beneficial effects of the utility model are: temperature before circulation cryogen flash distillation can be dropped by heat exchange after increasing refrigeration system
To about 15 DEG C, the effect of the circulation cryogen flash distillation after cooling is more preferable, reduces the temperature of reaction feed, directly reduces reactor
Reaction temperature, makes the quality of alkylation products be improved, it is suppressed that the generation of the side reaction in alkylated reaction.

Detailed description of the invention
New alkylation reaction unit, including reactor 1, acid settler 5, flash tank the 6, first compressor 7, separatory tank 8,
Second compressor 9, water cooler 10, surge tank 11, said apparatus is connected by pipeline 15, pipeline 15 arranges valve 16 and pump
17；Reactor 1 is divided into feeder 2, reacting part 3 and tube bank portion 4, and raw material is directly mixed with circulation cryogen and fed by reactor 1
Portion 2 enters reacting part 3, and hydrocarbon material spreads rapidly and forms emulsion with acid.Emulsion ceaselessly follows at a high speed in reactor 1
Ring, raw material is alkylated reaction, feeder 2 and reacting part 3 and is respectively communicated with acid settler 5, a part of reactant and sulphuric acid breast
Change liquid leads to acid settler 5 and carries out acid hydrocarbon separation, and acid is sunk to bottom acid settler 5 owing to density is relatively big, then gravity work
Reactor 1 reacting part 3 is returned to self-loopa；Acid settler 5 connects tube bank portion 4, and tube bank portion 4 connects flash tank 6, acid deposition
After the effluent of tank 5 takes reaction heat away to tube bank portion 4 after air relief valve reduces pressure, flash tank 6 reacts side and separates gas-liquid two-phase,
Gas phase enters after separatory tank 8 separates lime set as circulation cryogen through the first compressor 7, enters the second compressor 9 and compresses, then through water
Surge tank 11 is entered after cooler 10 cooling.
Arranging lithium bromide absorption chiller system between surge tank 11 and flash tank 6, described lithium bromide absorption chiller system includes heat exchanger
12, desalination water pot 13, lithium bromide refrigerator 14, heat exchanger 12 connects surge tank 11 and flash tank 6, heat exchanger 12, desalination water pot
13, lithium bromide refrigerator 14 forms blood circulation, and circulation cryogen enters flash tank after heat exchanger 12 makes temperature be down to 15 DEG C
6, the circulation refrigerant temperature that flash distillation side separates is down to-10 DEG C, and the circulation cryogen feeder 2 of pump 17 to reactor 1 mixes with raw material
Closing, owing to circulating the reduction of refrigerant temperature, the thermal discharge in alkylation process is well controlled, the fall of reaction temperature
The low quality making alkylation products is improved, it is suppressed that the generation of the side reaction in alkylated reaction.
Described lithium bromide refrigerator 14 includes suction tube 18, and the tube wall of suction tube 18 has solution suction passage 19, inhales
Material pipe is deep in its lithium-bromide solution container connected, and suction tube 18 is connected with solution pump 17, is passed through by lithium-bromide solution
Carry in suction tube 18 is drawn to solution pump 17 and by solution pump 17, suck logical owing to having solution on the tube wall of suction tube 18
Road 19 so that during solution pump 17 aspirates lithium-bromide solution, lithium-bromide solution can be sufficiently mixed with isooctanol activator,
Ensure that the heat exchange property of lithium-bromide solution, reduce the activating agent amount in the volatilization on lithium-bromide solution surface, extend activator
In the interpolation cycle, reduce the cost of activating agent.
Finally should be noted that: it is only limited by above example in order to the technical solution of the utility model to be described
System；Although being described in detail this utility model with reference to preferred embodiment, those of ordinary skill in the field should
Understand: still detailed description of the invention of the present utility model can be modified or portion of techniques feature is carried out equivalent and replace
Change；Without deviating from the spirit of technical solutions of the utility model, it all should contain the technical scheme being claimed at this utility model
In the middle of scope.
