Embodiment 1

[0032] This embodiment provides a figure 1 The shown integrated device for desulfurization based on triazine solution includes an absorption tower 1, and the absorption tower 1 is provided with an air inlet 101, an air outlet 102, a desulfurizing agent inlet 103, a desulfurizing agent outlet 104 and a sewage outlet 105. The air inlet 101 is connected to the inlet pipeline 2; the gas outlet 102 is connected to the exhaust pipeline 3, and the exhaust pipeline 3 is connected in series from upstream to downstream with a ball valve 1 301 and an online hydrogen sulfide detector 302; the desulfurizer inlet 103 and the desulfurizer outlet 104 are connected by circulation pipeline 4, circulation pipeline 4 is installed with circulation pump 401, desulfurizer inlet 103 is also connected with replenishment pipeline 5, replenishment pipeline 5 is connected with inlet of replenishment pump 501, outlet of replenishment pump 501 is connected with desulfurizer storage tank 502 The sewage outl...

Embodiment 2

[0038] On the basis of embodiment 1, the three-way ball valve 201 is connected in series on the air intake pipeline 2, and the third nozzle of the three-way ball valve 201 is connected with the natural gas external transmission bypass pipeline 202, and the natural gas external transmission bypass pipeline 202 is connected to Into the exhaust line 3.

[0039] Sulfur-containing natural gas can enter the absorption tower 1 through the three-way ball valve 201, or can not enter the absorption tower 1, but can be directly connected to the exhaust pipeline 3 through the natural gas export bypass pipeline 202 to be discharged.

Embodiment 3

[0041] On the basis of Embodiment 1, an electric emergency shut-off valve 601, a shut-off valve 602, an electric discharge regulating valve 603, and a shut-off valve 2 604 are connected in series from upstream to downstream in sequence on the sewage discharge pipeline 6. 602 , a bypass emergency liquid discharge valve 605 arranged in parallel with the liquid discharge electric control valve 603 and the shut-off valve 2 604 .

[0042] Under abnormal working conditions: when the triazine solution in the absorption tower 1 drops to a low level, the electric emergency cut-off valve 601 is used to shut off the sewage pipeline 6 urgently; under maintenance conditions, the discharge pipeline 6 can be cut off through the electric discharge regulating valve 603 ; When the liquid discharge electric control valve 603 fails, the emergency liquid discharge can be realized by bypassing the emergency liquid discharge valve 605 ;

[0043] The shut-off valve 1 602 and the shut-off valve 2 604 ...

Abstract

The invention provides an integration device based on desulfurization of a triazine solution and an application method of the integration device. The integration device comprises an absorption tower,wherein an air inlet of the absorption tower is connected with an air inlet pipeline; an air outlet of the absorption tower is connected with an exhaust pipeline; a ball valve 1 and an on-line hydrogen sulfide detector are connected in series with the exhaust pipeline; a desulfurizer inlet and a desulfurizer outlet are connected through a circulating pipeline on which a circulating pump is mounted; the desulfurizer inlet is further connected with a fluid infusion pipeline; the fluid infusion pipeline is connected with an inlet of a fluid infusion pump; an outlet of the fluid infusion pump is connected with a desulfurizer storage tank; a drain outlet is connected with a blowdown pipeline; and the on-line hydrogen sulfide detector is electrically connected with the fluid infusion pump for interconnected control. The integration device based on desulfurization of the triazine solution and the application method of the integration device simultaneously realize desulfurization, automatic circulation and fluid infusion, and the whole process is fully automatic and does not need manual intervention.

Description

technical field [0001] The invention belongs to the field of petroleum equipment, and in particular relates to an integrated device and method for desulfurization based on a triazine solution, in particular to a method for removing hydrogen sulfide ( h 2 S) An integrated device and method for automatic circulation and rehydration of triazine solution desulfurization. Background technique [0002] If the natural gas produced from the formation contains H 2 S, not only will cause corrosion to equipment and pipelines, but also bring environmental pollution, so it is necessary to remove H 2 S. According to the mass of sulfur element contained in natural gas, the scale of desulfurization treatment of natural gas can be divided into low latent sulfur content (less than 0.1t / d elemental sulfur), medium latent sulfur content (0.1-30t / d elemental sulfur) And high latent sulfur content (elemental sulfur higher than 30t / d) scale. [0003] For the purification of low latent sulfur ...
