no. 1 Embodiment approach

[0068] Next, the ammonia removal facility and the ammonia removal method according to this embodiment will be described with reference to the drawings.

[0069]

[0070] figure 1 It is a schematic diagram of the ammonia removal facility concerning 1st Embodiment.

[0071] The ammonia removal facility according to the first embodiment has a first ammonia removal device 1, is arranged in the rear stage of the first ammonia removal device 1, and processes the first process gas treated by the first ammonia removal device 1. The second ammonia removal device 2, the first ammonia concentration measuring device 11 for measuring the ammonia concentration in the first treated gas treated by the first ammonia removal device 1, and the first ammonia concentration measurement device 11 for measuring the ammonia concentration by the second ammonia removal device 2 A second ammonia concentration measuring device 21 for the ammonia gas concentration in the processed second processing gas....

no. 2 Embodiment approach

[0156]

[0157] figure 2 It is a schematic diagram of the ammonia removal facility concerning 2nd Embodiment.

[0158] The ammonia removal facility according to the second embodiment has a first ammonia removal device 1, is installed in the rear stage of the first ammonia removal device 1, and processes the first process gas treated by the first ammonia removal device 1. The 2nd ammonia removal device 2, and the ammonia gas concentration in the 1st process gas that can be processed by the 1st ammonia removal device 1 and the ammonia concentration in the 2nd process gas that is processed by the 2nd ammonia removal device 2 The first ammonia concentration measuring device 31 of the ammonia gas concentration.

[0159] The piping 3 provided with the on-off valve 3v is connected to the inflow port of the said 1st ammonia removal apparatus 1. The outlet of the first ammonia removal device 1 and the inlet of the second ammonia removal device 2 are connected via a pipe 4 provided...

no. 3 Embodiment approach

[0179]

[0180] image 3 It is a schematic diagram of the ammonia removal facility concerning 3rd Embodiment.

[0181] In this ammonia removal facility, in the ammonia removal facility according to the first embodiment, instead of the first ammonia removal device 1 and the on-off valve 3v, a plurality of (two in this embodiment) first ammonia removal containers installed in parallel are used. The first ammonia removal device 1A of 1a, 1b and the three-way valve 3e are the same as the ammonia removal facility according to the first embodiment.

[0182] In addition, the same code|symbol as the ammonia removal facility which concerns on 1st Embodiment shows the same part.

[0183] Specifically, the first ammonia removal device 1A has two first ammonia removal containers 1a, 1b installed in parallel, is divided into two from the rear stage of the piping 3, and is connected to the flow of the two first ammonia removal containers 1a, 1b. Two pipes 3a, 3b connected to the inlet, ...

Abstract

Provided is ammonia removal equipment etc., said equipment comprising: a first ammonia removal apparatus that removes ammonia in a mixed gas containing hydrogen and ammonia; a second ammonia removal apparatus that is installed at a subsequent stage to the first ammonia removal apparatus, and that processes a first processed gas processed by the first ammonia removal apparatus; and a first ammoniaconcentration measurement device that measures the ammonia concentration in the first processed gas processed by the first ammonia removal apparatus.

Description

technical field [0001] The invention relates to ammonia removal equipment, an ammonia removal method and a hydrogen production method. Background technique [0002] Hydrogen is highly anticipated as the ultimate clean energy. For example, hydrogen can be used as a fuel gas for fuel cells. This hydrogen gas can be produced by electrolysis of water, or steam reforming of natural gas, coal, or waste plastics. [0003] However, if the hydrogen gas used as the fuel gas contains ammonia gas as an impurity, the ammonia gas will adversely affect the electrolyte membrane and catalyst layer in the fuel cell. Therefore, the fuel gas is supplied to the fuel cell after being introduced into the adsorber to remove the ammonia gas. [0004] In addition, two adsorbers are installed in parallel, and these two adsorbers are alternately replaced for operation. This makes it possible to regenerate the adsorbent supplied to the adsorber in the stopped state after the operation, and to contin...
