Abstract
This utility model relates to a kind of double off loading and puts solvent regeneration tower treatment with improver system.Mainly solve the problem that the operating solvent regeneration tower of existing system cannot normally produce qualified solvent because contamination of raw material generation foamed phenomenon makes regenerator rush tower.It is characterized in that: on described solvent regeneration tower (1) top and overhead reflux pipeline, connect reflux pump (4), return tank (5), cooler (6), reflux pump (4) suction line on described reflux pipeline connects discharging valve (7), the connection pipeline of discharging valve 7 connects dosing pump (8), dosing pump (8) outlet line is passed through defoamer bucket (9), and described dosing pump (8) connects Pressure gauge (10).This pair of off loading puts solvent regeneration tower treatment with improver system, it is possible to the problem solving online to rush tower because of solvent bank oil aeration, it is not necessary to stop work, it is possible to provide qualified desulfurization solvent for downstream unit, it is ensured that desulfurized effect.
Description
Technical field
This utility model relates to a kind of processing system in technical field of petrochemical industry, and particularly a kind of double off loadings put solvent again
Raw tower treatment with improver system.
Background technology
Double desolventizing regenerator effects are the rich amine solution containing high-concentration hydrogen sulfide to be carried out rectification regeneration, in rich amine solution
Hydrogen sulfide parse and distillated carrying device by tower top, the lean amine liquid after being regenerated at the bottom of tower, for desulfuration of liquefied gas, dry
Desulfurization, sulfur recovery tail gas desulfurization and gasoline hydrogenation device provide the lean amine liquid of qualified quality.This device uses hydramine method to take off
Sulfur, the solvent strength of use is the MDEA(methyl diethanolamine of 30～35%) aqueous solution.
In long-term production process, solvent can be affected by feedstock property, and each device raw material components change can cause amine liquid
Band oil, by pollution in various degree, causes regenerator operation disorder, rich amine solution can not regular regeneration, thus affect above-mentioned dress
The desulfurized effect put, causes the product such as liquefied gas, dry gas defective.Such as: the rich amine solution that gasoline hydrogenation returns is containing light oil
495ppm, at the bottom of rich amine solution oil-containing 108ppm, the DCC dry gas desulfurizing tower that sulphur recovery returns, rich amine solution is containing 198ppm.These oil
Along with rich amine solution enters solvent regeneration tower, rich amine solution entering tower flow rate is 34 ton hour, and regenerator oil inlet quantity exists the most per hour
8.37kg.Longtime running, regenerator amasss oil too much makes the foaming of amine liquid cause rushing tower, and solvent regeneration tower is in paralyzed state, makes
Become the desulfurizing agent desulfurizing function that loses the most up to standard, thus qualified desulfurizing agent cannot be provided for said apparatus.Such as, desulfurized effect pole
Difference, in dry gas, hydrogen sulfide content exceeds standard, and directly affects the temperature of device for producing hydrogen reactor, and catalyst will be caused to lose because of overtemperature coking
Effect (catalyst value more than million yuan), consequence is serious.The impact that this situation is the most serious produces, and also directly results in product quality
The generation of accident, makes the products such as MTBE, propylene, propane to sell and dispatches from the factory, and loss is serious.
Summary of the invention
Technical problem to be solved in the utility model is to overcome existing system present in background technology operating molten
Agent regenerator cannot normally produce the problem of qualified solvent because contamination of raw material generation foamed phenomenon makes regenerator rush tower, and provides
A kind of double off loading puts solvent regeneration tower treatment with improver system, and this pair of off loading puts solvent regeneration tower treatment with improver system, it is possible to online
The problem solving to rush tower because of solvent bank oil aeration, it is not necessary to stop work, it is possible to provide qualified desulfurization solvent for downstream unit, it is ensured that
Desulfurized effect.
The invention for solving the technical problem can reach by following technical solution: this pair of off loading is put solvent regeneration tower and added agent
Processing system, including solvent regeneration tower, described solvent regeneration tower connects rich amine solution feeding line, and solvent regeneration tower column bottoms pump connects
Lean amine liquid pipeline, connection reflux pump, return tank, cooler on described solvent regeneration tower top and overhead reflux pipeline, described time
Reflux pump suction line on flow tube line connects discharging valve, and the connection pipeline of discharging valve connects dosing pump, dosing pump outlet line
Being passed through defoamer bucket, described dosing pump connects Pressure gauge.
This utility model can have the advantages that compared with above-mentioned background technology this pair of off loading puts solvent regeneration tower
Treatment with improver system, it is achieved that pressure vessel solvent reclamation without stop work, tower without perforate, undamaged in the case of, in tower body
Portion is directly added into defoamer, promptly the oils emulsifying carried in tower is cracked, and eliminates the factor causing amine liquid to foam, it is ensured that
Gas desulfurization quality, catalyst service life and the product export of protection device for producing hydrogen are qualified, directly save the millions of unit of fund.
Ensure the desulfurization solvent that downstream unit offer is qualified, it is ensured that desulfurized effect.
Accompanying drawing explanation
Accompanying drawing 1 is system structure schematic diagram of the present utility model.
In figure: 1-solvent regeneration tower, 2-rich amine solution feeding line, 3-lean amine liquid pipeline, 4-reflux pump, 5-return tank, 6-
Cooler, 7-discharging valve, 8-dosing pump, 9-defoamer bucket, 10-Pressure gauge.
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 pair of off loading puts solvent regeneration tower treatment with improver system, including solvent regeneration tower 1, described solvent
Regenerator 1 connects rich amine solution feeding line 2, and solvent regeneration tower 1 column bottoms pump connects lean amine liquid pipeline 3；On described solvent regeneration tower 1
Reflux pump 4, return tank 5, cooler 6, reflux pump 4 suction line on described reflux pipeline is connected in portion and overhead reflux pipeline
Connecting discharging valve 7, the connection pipeline of discharging valve 7 connects dosing pump 8, and dosing pump 8 outlet line is passed through defoamer bucket 9, described meter
Amount pump 8 connects Pressure gauge 10.
When this pair of off loading puts the use of solvent regeneration tower treatment with improver system, the defoamer in defoamer bucket is extracted out by dosing pump
Enter into reflux inlet by reflux pump discharging valve again to pump discharge line, arrive solvent regeneration tower through reflux pump outlet.Make use of
The entrance discharging valve of regenerator reflux pump is as the entrance of addition defoamer, thus defoamer is admitted in tower along with backflow.
Scheme implements safe and simple convenience, need not stop work, and has not only avoided tedious work that pressure vessel Commission Design perforate brings but also has kept away
Exempt from the danger that hydrogen sulfide leakage brings, effectively solved amine liquid and pollute the production difficult problem that foaming brings.This pair of off loading is put
Solvent regeneration tower treatment with improver system in grand celebration blue stoneization implement after, for the desulfuration of liquefied gas device of 200,000 tons/year, every year
Can save because the amine liquid expense of foaming loss reaches more than 20 ten thousand yuan.
