The waste hydrogen reutilization device comprises a circulating hydrogen buffer tank, a coking dry gas desulphurization device, a circulating hydrogen compressor and an oil reduction line low-grade removal device, wherein a pipeline on the top of the circulating hydrogen buffer tank is connected to a flare system, a pipeline and a flow adjusting valve are additionally arranged in front of the waste circulating hydrogen discharging flare system, and the flow adjusting valve is connected to the dry gas desulfurization device; the coking dry gas desulphurization device and the circulating hydrogen compressor are connected to the pipeline on the top of the circulating hydrogen buffer tank through a pipeline, the oil reduction line low-grade removal device is connected to a pipeline at the bottom of the circulating hydrogen buffer tank through a pipeline, and a circulating hydrogen inlet is formed in the circulating hydrogen buffer tank. The waste hydrogen reutilization device is used for solving the problem of reutilization of waste hydrogen used in a hydrogenation circulating-hydrogen-free hydrogenation device technology and has the advantages that the fuel gas flow is increased, the environmental pollution is reduced, coking dry gas enters a hydrogen production unit so as to serve as a hydrogen production raw material, so that the hydrogen content of the hydrogen production raw material is increased, and the hydrogen production cost is reduced.
Description
Technical field
The utility model belongs to useless hydrogen re-use device, relates in particular to a kind of useless hydrogen re-use device for hydrogenation unit.
Background technology
At present, the useless hydrogen discharge of 700,000/year hydrogenation unit recycle hydrogen 800Nm
3/ hour, its hydrogen purity is more than 90%, hydrogen sulfide content 5000ppm, and existing hydrogenation unit does not have desulphurization of recycle hydrogen device, and the useless hydrogen of discharge cannot utilize, and discharge flare system had not only caused significant wastage but also severe contamination air.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defect that prior art exists, and a kind of useless hydrogen re-use device that is applicable to hydrogenation unit is provided.
For solving this technical problem, the utility model provides a kind of useless hydrogen re-use device of hydrogenation unit, comprise recycle hydrogen surge tank, coking Upgrade for Dry Gas Desulphurization Unit, circulating hydrogen compressor and subtract oily line and remove low separating device, the overhead line of recycle hydrogen surge tank is connected with flare system, before the useless hydrogen discharge of recycle hydrogen flare system, increase pipeline and flow control valve, described flow control valve connects into Upgrade for Dry Gas Desulphurization Unit.
Described coking Upgrade for Dry Gas Desulphurization Unit is connected with recycle hydrogen surge tank overhead line by pipeline with circulating hydrogen compressor, subtracts oily line and goes low separating device to be connected with recycle hydrogen surge tank bottom line by pipeline, is provided with recycle hydrogen entrance on recycle hydrogen surge tank.
Beneficial effect: the utility model has solved and has now been used in hydrogenation without the problem of useless hydrogen recycling in desulphurization of recycle hydrogen device technique, increased fuel gas flow, reduced again environmental pollution, coking dry gas enters Hydrogen Unit to be done hydrogen feedstock and has increased hydrogen feedstock hydrogen content, has reduced hydrogen manufacturing cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 recycle hydrogen surge tank, 2 coking Upgrade for Dry Gas Desulphurization Units, 3 torches, 4 circulating hydrogen compressors, 5 recycle hydrogen entrances, 6 subtract oily line and remove low separating device, 7 flow control valves.
Embodiment
The utility model is installed on the useless hydrogen discharge of original design flare system, the useless hydrogen recycling for gasoline and diesel hydrogenation without desulphurization of recycle hydrogen device.
Below in conjunction with drawings and Examples, the utility model is specifically described.
Figure 1 shows that structural representation of the present utility model.
The utility model comprises recycle hydrogen surge tank 1, coking Upgrade for Dry Gas Desulphurization Unit 2, circulating hydrogen compressor 4 and subtracts oily line and removes low separating device 6.
Described coking Upgrade for Dry Gas Desulphurization Unit 2 is connected with recycle hydrogen surge tank 1 overhead line by pipeline with circulating hydrogen compressor 4, subtracting oily line goes low separating device 6 to be connected with recycle hydrogen surge tank 1 bottom line by pipeline, on recycle hydrogen surge tank 1, be provided with recycle hydrogen entrance 5, the overhead line of recycle hydrogen surge tank 1 is connected with torch 3 systems.
For guaranteeing dry gas thionizer pressure and load, before the useless hydrogen discharge of recycle hydrogen torch 3 systems, increase pipeline and flow control valve 7, described flow control valve 7 connects into Upgrade for Dry Gas Desulphurization Unit 2, the regulation system torch 3 of can setting fire during hydrogenation system hypertonia, when too low, flow control valve 7 cuts out, assurance hydrogenation, coking are stablized post and can steadily be produced.
This practical hydrogenation unit gasoline, diesel oil, hydrogen passes through reactor reaction, the unnecessary hydrogen of unreacted and reaction product gas enter hydrogenation recycle hydrogen surge tank 1 through cooling by recycle hydrogen entrance 5, flow control valve 7 is removed at recycle hydrogen surge tank top, dry gas desulfurization is stablized in 2 coking of defocusing Upgrade for Dry Gas Desulphurization Unit again, torch 3 Controlling System pressure reduce internal heat at recycle hydrogen surge tank 1 top, hydrogenation recycle hydrogen press 4 system stability hydrogenation system hydrogen-oil ratios are removed at recycle hydrogen surge tank 1 top, recycle hydrogen surge tank 1 bottom is removed to subtract oily line and is gone low separating device 6 separators to subtract oil, increased fuel gas flow, reduced again environmental pollution, coking dry gas enters Hydrogen Unit to be done hydrogen feedstock and has increased hydrogen feedstock hydrogen content, reduced hydrogen manufacturing cost.
The utility model enters coking by the useless hydrogen of recycle hydrogen and stablizes dry gas desulphurization system, the hydrogen that will give up mixes laggard stable dry gas desulphurization system with stable post non-condensable gas, solved and be now used in hydrogenation without the problem of useless hydrogen recycling in desulphurization of recycle hydrogen device technique, increased fuel gas flow, reduced again environmental pollution, coking dry gas enters Hydrogen Unit to be done hydrogen feedstock and has increased hydrogen feedstock hydrogen content, has reduced hydrogen manufacturing cost.
The above-mentioned embodiment of the utility model, just illustrates, and is not only, all within the scope of the utility model or the change being equal in scope of the present utility model all by the utility model, surrounded.
