Abstract
The utility model relates to a separation system for recovering gasoline components carried by gasoline sweetening emptied oil gas, which mainly solves the problem that noncondensable gas emptied for adjusting pressure can carry a certain amount of gasoline components so as to cause gasoline loss in the prior art. The separation system is characterized in that a pipeline above a gasoline tank (1) is connected with a condenser (3); an emptying valve (2) is connected with a pipeline between the gasoline tank (1) and the condenser (3); a pipeline below the condenser (3) is connected with a middle tank (4); a pipeline below the middle tank (4) is connected with a valve A (5); a pipeline at the bottom of the gasoline tank (1) is connected with a valve B (7); and the valve A (5) and the valve B (7) are connected with an oil pump (6). The separation system can be used for recovering the gasoline components carried by oil gas so as to reduce loss.
Description
Technical field
[0001] the utility model relates in the petrochemical industry recovery piece-rate system of active principle, particularly a kind of piece-rate system that reclaims entrained gasoline component in the demercaptaning for gasoline emptying oil gas in a kind of emptying oil gas.
Background technology
[0002] along with the improving constantly of automobile exhaust emission standard, the high-clean gasoline demand strengthens gradually, need to remove in a large number from the mercaptan in the high sour gasoline of petrochemical plant.Reclaiming the demercaptaning for gasoline blowdown system, the removal of mercaptans gasoline of 50 ℃ of 0.45MPa by reactor enters the gasoline pans, and the pressure of gasoline pans is regulated by the emptying valve, and the gasoline in the gasoline pans is sent to next unit through oil pump.Pans fixed gas of emptying when regulating pressure can carry a certain amount of gasoline component together to be put to atmosphere, causes the loss of a certain amount of gasoline.
Summary of the invention
Technical problem to be solved in the utility model is that the fixed gas that overcomes the adjusting pressure-emptying that exists in the background technology can carry the problem that a certain amount of gasoline component causes the gasoline loss, and provide a kind of piece-rate system that reclaims entrained gasoline component in the demercaptaning for gasoline emptying oil gas, this reclaims the piece-rate system of entrained gasoline component in the demercaptaning for gasoline emptying oil gas, can reclaim the gasoline component that carries in the oil gas, reduce the loss.
The invention for solving the technical problem can reach by following technical solution: the piece-rate system of entrained gasoline component comprises gasoline cistern in this recovery demercaptaning for gasoline emptying oil gas, described gasoline cistern upper pipeline connects condenser, be connected atmospheric valve on the pipeline between gasoline cistern and condenser, the condenser pipeline connects pans, the pans lower pipelines connects valve A, be connected with valve B on the gasoline cistern bottom line, valve A, valve B connect oil pump.
The utility model is compared with the above-mentioned background technology can have following beneficial effect: the piece-rate system of entrained gasoline component in this recovery demercaptaning for gasoline emptying oil gas, owing to adopt said structure, can reclaim the gasoline component that carries in the oil gas, technique is simple, has dropped to the loss of the gasoline in the process minimum.
Description of drawings:
Among the figure: 1-gasoline cistern, 2-atmospheric valve, 3-condenser, 4-pans, 5-valve A, 6-oil pump, 7-valve B.
The specific embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
As shown in Figure 1, the piece-rate system of entrained gasoline component comprises gasoline cistern 1 in this recovery demercaptaning for gasoline emptying oil gas, described gasoline cistern 1 upper pipeline connects condenser 3, be connected atmospheric valve 2 on the pipeline of gasoline cistern 1 and 3 of condensers, condenser 3 lower pipelines connect pans 4, pans 4 lower pipelines connect valve A5, are connected with valve B7 on gasoline cistern 1 bottom line, and valve A5, valve B7 connect oil pump 6.
When this reclaims the piece-rate system operation of entrained gasoline component in the demercaptaning for gasoline emptying oil gas, after the material that allows atmospheric valve 2 discharge passes through the condensing cooling of condenser 3, the gasoline component that carries in the gas phase is separated from gas phase, the liquid phase gasoline of separating enters pans 4 and stores, when pans 4 reach certain liquid level, valve-off B7 opens valve A5, through oil pump 6 gasoline in the pans 4 is seen off.Be 280,000 tons demercaptaning for gasoline device for a disposal ability, about 12.5 tons of annual recyclable gasoline.
Claims (1)
1. piece-rate system that reclaims entrained gasoline component in the demercaptaning for gasoline emptying oil gas, comprise gasoline cistern (1), it is characterized in that: described gasoline cistern (1) upper pipeline connects condenser (3), be connected atmospheric valve (2) on the pipeline between gasoline cistern (1) and condenser (3), condenser (3) lower pipelines connects pans (4), pans (4) lower pipelines connects valve A(5), be connected with valve B(7 on gasoline cistern (1) bottom line), valve A(5), valve B(7) connect oil pump (6).
