Abstract
The utility model relates to a hydrogen demister device in a pressure swing adsorption system. The hydrogen demister device comprises a mesh demister and a pressure swing adsorption tower, wherein a demister for removing oil mist and water mist in hydrogen is arranged behind the mesh demister and in front of the pressure swing adsorption tower. With the adoption of the hydrogen demister device disclosed by the utility model, the hydrogen demister device can be used for more than 10 years after a test; the mist collection efficiency is high and the pressure drop is stable; and a downstream pressure swing adsorption layer does not need to be replaced.
Description
Technical field
The utility model relates to hydrogen demister device in a kind of pressure swing adsorption system.
Background technology
In large-scale petroleum smelting enterprise, in order to slough sulphur, the hydrogen sulfide in the crude oil, need to expend a large amount of hydrogen and go to react.After certain course of reaction, can be mingled with in the hydrogen other components other, need in a tower body, to adopt adsorbent bed to hydrogen purification by the pressure-variable adsorption principle.If but carry water smoke in the hydrogen secretly and mist of oil can make the adsorbent bed poison deactivation very soon, thereby produce huge renewal cost.
The large multiple enterprises of pressure-variable adsorption workshop section adopts mesh mist eliminator except water smoke on the domestic market now, adopts molecular sieve, active carbon or organosilicon to absorb moisture and mist of oil behind the mesh mist eliminator before the adsorbent bed.
To need regeneration to use after absorbing certain moisture and mist of oil but the problem that the method exists is molecular sieve, active carbon or organosilicon, moisture then needs when surpassing certain value to replace.And these medium volumes are larger, make pressure-variable adsorption workshop section shell dimension and weight become large.
Summary of the invention
For overcoming above-mentioned prior art problem, the utility model proposes hydrogen demister device in a kind of pressure swing adsorption system.
After mesh mist eliminator 6, before the pressure-swing absorber 7, be provided with the demister 1 except mist of oil, water smoke in the hydrogen.
The course of work: the hydrogen of carrying water smoke and mist of oil secretly is entered by gas access 3, by demister 1 water smoke in the gas and mist of oil is collected, and clean gas enters downstream pressure-swing absorber 7 and adsorbent bed 8 by gas vent 4, and liquid is discharged from leakage fluid dram 5.
Further, demister is provided with for carrying the hydrogen gas entrance 3 of water smoke and mist of oil secretly, discharges the gas vent 4 that connects pressure-swing absorber 7 adsorbent bed 8 for clean gas, and demister bottom discharge for liquid from leakage fluid dram 5.
Demister gas access and gas outlet are provided with differential manometer 2.
Description of drawings
Fig. 1 is hydrogen demister device schematic diagram in a kind of pressure swing adsorption system of the present utility model.
Fig. 2 is hydrogen demister apparatus structure schematic diagram in a kind of pressure swing adsorption system of the present utility model.
Among the figure: the 1-demister; The 2-differential manometer; The 3-gas access; The 4-gas vent; The 5-leakage fluid dram; The 6-mesh mist eliminator; The 7-pressure-swing absorber; 8-is adsorbent bed.
The specific embodiment
Among Fig. 1, after mesh mist eliminator 6, before the pressure-swing absorber 7, be provided with the demister 1 except mist of oil, water smoke in the hydrogen.Among Fig. 2, the hydrogen of carrying water smoke and mist of oil secretly is entered by gas access 3, by demister 1 water smoke in the gas and mist of oil is collected, and clean gas enters downstream pressure-swing absorber 7 and adsorbent bed 8 by gas vent 4, and liquid is discharged from leakage fluid dram 5.Demister gas access and gas outlet are provided with differential manometer 2, can pass through in the simple monitoring of running the pressure reduction of this unit, can shut down maintenance when unusual generation is arranged.Demisting unit adopts fiber bed mist eliminator, but the sub-micron mist that general defogging equipment can't be processed in the effective separation gas.Therefore can guarantee that water smoke and the lubricant mist carried secretly in the hydrogen are effectively collected; The concrete structure of demister can be referring to notification number 201524499U, and name is called the patent content of " a kind of demister element of eliminating reentrainment ".
The utility model separate mode is that mechanical type separates, and working stability is reliable, the maintain and replace expense is low.
Following is operating position with hydrogen demister device in the pressure swing adsorption system of certain large-scale oil refinery company, and concrete operating mode is as follows:
Hydrogen flowing quantity: 2769ACFM (4705Am3/h);
Operating pressure: 300psia (2.07MPa);
Operating temperature: 100Deg F (37.8Deg C);
Water smoke and oil moisture content: 100mg/ACFM (3534mg/Am3).
Test result:
Demist efficient: 99.5%
Pressure drop: 6.86kPa.
Adopt this demister, after tested, the stable use more than 10 years, the mist collection efficiency is high, pressure drop is stable, and the pressure-variable adsorption bed in downstream need not to replace.
