The invention discloses the combined non-decile dividing wall column of the multistage with gas-liquid modulator, including：By supporting body flange and supporting feed and exhaust tube at the top of the non-decile dividing wall column section of multistage, one or more groups of gas-liquid modulators, rectifying column.The combined non-decile dividing wall column of the multistage with the gas-liquid modulator operating flexibility that solves rectifying column of the present invention is small, production technology project setting is difficult and the investment of multi-component masses knockout tower is big, the problem of high energy consumption.
Description
Technical field
The rectifying column of fractional distillation process, belongs to technical field of petrochemical industry in being produced the present invention relates to petrochemical industry.
Background technology
In chemical separation process, rectifying column is most widely used fractionation separation equipment, but defect is to invest big, energy consumption
Higher, in the industries such as oil refining, petrochemical industry, the ratio that its energy consumption accounts for overall process is even as high as 70%, and equipment investment is more than 50%.
Partitioned column has low energy consumption and inexpensive huge advantage as novel distillation tower for multicomponent rectification.At present
Be mainly used in ternary mixture separation, partitioned column be in common rectifying column along longitudinally disposed one piece of dividing plate of tower, every
Plate will be divided into the subregions such as left and right two in the middle part of tower body, and compared to common rectifying column, the uprising gas of dividing plate tower bottom will
It is allocated in dividing plate both sides, product purity and energy consumption in the gas apportioning cost influence distillation process of dividing plate both sides, appropriate
The purity of rectifying product can also be significantly increased in the energy consumption that gas apportioning cost can not only reduce partitioned column.
Iris type rectifying column is generated more operation frees degree, is saved and obtained due to its structure and the complexity of technique
The product not a duck soup of high-purity is taken, it is necessary to the controllability of internal system variable is stronger, cause iris type rectifying column every control
Problem becomes a principal element for hindering its commercial Application, will particularly enter the uprising gas of dividing plate tower bottom in dividing plate
Both sides are allocated, and this apportioning cost influences the product purity and energy consumption in distillation process, and appropriate gas apportioning cost not only may be used
To reduce the energy consumption of partitioned column, the purity of rectifying product can also be significantly increased, the air flow rate of both sides how to distribute and
Effective control problem turns into industry focus of attention.Relative to common rectifying column, iris type rectifying column need regulation simultaneously every
Plate upper end drops to the liquid of dividing plate both sides and bottom of towe rises to the gas of dividing plate both sides.Adjusted because gas distributes in dividing plate both sides
Section is related to the elevation computation of complexity, the dynamic analog of operating parameter, the series of computation process such as analysis in gas-liquid two-phase flow field,
Thus, very high difficulty be present in the distribution regulation and control of dividing plate both sides gas.
At present, generally by the way of gas freely distributes in dividing plate both sides, the ratio freely distributed is by partitioned column
Portion's component（Such as packed height, the column plate number of plies, flow channel area）Determined with the operation operating mode in tower, the rising gas of bottom of towe
Body will comply with the equal rule of left and right sides pressure drop and be automatically assigned to dividing plate both sides.
The weight of gas distribution is influenceed because the change of feed composition and state and the allocation proportion etc. of liquid can all turn into
Factor is wanted, thus the gas flow ratio distributed automatically in dividing plate both sides can not usually reach the optimal operating conditions of partitioned column.
Gas distribution regulation and control are that the special inner member of design is formed to adjust gas phase distribution to change the pressure drop of dividing plate both sides
Purpose, for example, installed in the bottom of dividing plate one piece can with the baffle plate of shift position, by the change in location of the baffle plate come change every
The circulation area of plate both sides, so as to change gas phase distribution ratio, change dividing plate both sides using inner member or by the eccentric placement in next door
Pressure drop, not only its operating flexibility is smaller, sensitivity is low, and due to mechanical wear caused by baffle plate movement so that equipment can not
Long-period stable operation.
A kind of dividing plate fractionating column and its gas-liquid flow control methods are disclosed in PCT/US2011/056079 patent documents,
The dividing plate fractionating column includes tower body, gas phase is collected and distribution structure and liquid phase collection and distribution structure, wherein, gas phase is collected and divided
With mainly by the bypass gas phase pipeline with regulating valve and flowmeter outside tower, with reference to automatically control the distribution of realizing gas with
Control.The technical scheme major defect is：Firstly, since gas phase is drawn and gas phase is again introduced into tower and is required to set in Ta Nei
Gas phase redistribution is put, so adding the complexity of tower height and internals；Secondly, for the larger dividing plate of production disposal ability
Tower, the diameter for bypassing gas phase pipeline can be very big, and associated components installation and maintenance are inconvenient；Again, for regulating valve and stream
The bypass gas phase pipeline of gauge, tower height is not only increased, the characteristic of gas flow pressure drop will also become sufficiently complex, and pressure drop is excessive
The downspout liquid flooding below dividing plate can be caused, system is by cisco unity malfunction；Finally, the size of regulating valve becomes with scale
Change, investment will become sufficiently expensive, and can not sensitively and accurately regulate and control gas phase flow rate in the range of lower drag drop.
Chinese patent 201320829355.2 disclose it is a kind of be used for partitioned column in gas preparing, using flow detection,
Controller, cylinder, dividing plate, square separate slot, downspout, inlet channel, square valve block governor motion, sleeve, rotating shaft, motor are gentle
Body distribution mechanism.The design defect being primarily present is：It is irregular performance of control curve to be present in adjusting gas flow, it is not easy to real
Now finely tune, the defects of adjustment control is regular poor, and tolerance is non-linear；The resistance drop reaction of dividing plate both sides gas can lag, square
Valve block does not possess fine setting characteristic, causes the sane regulation difficult to realize of square valve block governor motion；Due to there is transmission parts in tower, profit
Sliding and wear problem is relatively difficult to resolve the long period normal operation that can certainly influence equipment.
Aforementioned barriers formula rectifying column thermal coupling technological operation variable is more, and many parameters intercouple, dividing plate both sides
Gas flow and its dependent variable physical relation it is complicated, gas is to ensure production in effective distribution of dividing plate both sides and robust control
Product index and the important means for reducing energy consumption, urgent need have advanced technological means to solve this industrial problem.
