Abstract

This utility model relates to a kind of carbon four segregation apparatus decarburization three tower energy saving reforming system.Mainly solve existing apparatus thick iso-butane component and enter the extraction aqueous high problem of product diesel oil at the bottom of decarburization three-tower rectification waste mass energy fund employing Single-tower stripping tower.It is characterized in that: described deisobutanizer (1) overhead reflux pipeline connect return tank A(7), reflux pump A(2);Described return tank A(7) one outflow pipeline (9) of tower top connection, described outflow pipeline (9) is connected to gas separation unit;Described deisobutanizer (1) overhead reflux pipeline is connected to feeding line (10) in the middle part of decarburization three tower (4) tower, and the upper connection of described feeding line (10) has control valve (11).This carbon four segregation apparatus decarburization three tower energy saving reforming system, can be completely isolated for decarburization three tower when device inlet amount is relatively low, and thick carbon three removes gas separation unit, reduces energy consumption and saves substantial contribution.

Description

Carbon four segregation apparatus decarburization three tower energy saving reforming system
Technical field
This utility model relates to a kind of energy saving reforming system in technical field of petrochemical industry, and particularly a kind of carbon four separates dress Put decarburization three tower energy saving reforming system.
Background technology
Carbon four isolation technics of carbon four segregation apparatus is to introduce University Of Yantai's extraction and distillation technology, carbon three in this device raw material Content is about 1%, is gone out by the carbon three components separation in iso-butane in decarburization three tower.Thus it is pure not affect iso-butane product Degree.According to existing production procedure, thick iso-butane component enters decarburization three-tower rectification, and tower top obtains carbon three component of 75%, different at the bottom of tower Butane-component.Decarburization three pressure tower 2.0Mpa, temperature 80 degree, plant energy consumption is relatively big, applies decarburization three when device inlet amount is relatively low Tower, wastes a large amount of energy consumption, fund.And the gas separation unit of DCC produces continuously, does not reaches full load operation.
Summary of the invention
Technical problem to be solved in the utility model is to overcome existing apparatus thick iso-butane group present in background technology The problem point entering decarburization three-tower rectification waste mass energy fund, and provide that a kind of carbon four segregation apparatus decarburization three tower is energy-conservation changes Manufacturing system, this carbon four segregation apparatus decarburization three tower energy saving reforming system, can be complete for decarburization three tower when device inlet amount is relatively low Isolation, thick carbon three removes gas separation unit, reduces energy consumption and saves substantial contribution.
The invention for solving the technical problem can reach by following technical solution: this carbon four segregation apparatus decarburization three tower saves Energy modernization system, including deisobutanizer, described deisobutanizer overhead reflux pipeline connects return tank A, reflux pump A;Described Return tank A tower top connects one and flows out pipeline, and described outflow pipeline is connected to gas separation unit;Described deisobutanizer overhead reflux Pipeline is connected to feeding line in the middle part of decarburization three tower tower, and described feeding line connects control valve.
This utility model can have the advantages that compared with above-mentioned background technology this carbon four segregation apparatus of application takes off Before carbon three tower energy saving reforming system, decarburization three pressure tower 2.0Mpa, temperature 80 degree, plant energy consumption is bigger;After applying this technology, dress Put inlet amount relatively low time can be completely isolated for decarburization three tower, thick carbon three removes gas separation unit, makes full use of the gas separation unit of DCC even Continue and produce up to the present situation less than full load operation, reduce energy consumption, saved substantial contribution.
Accompanying drawing explanation
Accompanying drawing 1 is system flow chart of the present utility model.
In figure: 1-deisobutanizer, 2-reflux pump A, 3-column bottoms pump A, 4-decarburization three tower, 5-reflux pump B, 6-column bottoms pump B, 7-return tank A, 8-return tank B, 9-tower top flows out pipeline, 10-feeding line, 11-control valve.
Detailed description of the invention:
The utility model is described in further detail below in conjunction with the accompanying drawings:
As shown in Figure 1, this carbon four segregation apparatus decarburization three tower energy saving reforming system, including deisobutanizer 1, decarburization three Tower 4, described deisobutanizer 1, decarburization three tower 4 overhead line connect return tank A7, reflux pump A2 and return tank B8, backflow respectively Pump B5, described deisobutanizer 1 overhead reflux pipeline is connected to feeding line 10 in the middle part of decarburization three tower 4 tower, described feeding line Connect on 10 and have control valve 11;Described return tank A7 tower top flows out pipeline 9 and is connected to gas separation unit;Described deisobutanizer 1, de- Pipeline at the bottom of carbon three tower 4 tower connects column bottoms pump A3, column bottoms pump B6 respectively.
Before applying this carbon four segregation apparatus decarburization three tower energy saving reforming system, decarburization three pressure tower 2.0Mpa, temperature 80 degree, Plant energy consumption is bigger;After applying this technology, can be completely isolated for decarburization three tower when device inlet amount is relatively low, thick carbon three removes edema caused by disorder of QI Device, stops 2 pumps, saves electricity 20kw/h, adds up to 20 × 80,00h,=16 ten thousand kw/h every year, by often degree electricity 0.5 yuan, and altogether 8 Wan Yuan;1 ton/h of steam, adds up to 1 × 8000h=8000 ton, steam per ton 150 yuan every year, amounts to 1,200,000 yuan every year.500,000 Ton/year carbon four segregation apparatus every year amount to saving fund 1,280,000 yuan.
When this carbon four segregation apparatus decarburization three tower energy saving reforming system runs, thick iso-butane component enters DCC's with gas phase Gas separation unit, and decarburization three tower of this device just can go into operation.Because gas separation unit is to produce continuously, thick iso-butane component The gas separation unit entering DCC the most simply increases inlet amount, and the gas separation unit of DCC can not arrive full load operation in the past, this Sample decarburization three tower is stopped work just can save substantial contribution.
