本発明は水素吸蔵合金を用いた水素ガス精製システムに
適用される凝縮性ガスの分離方法及び装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a condensable gas separation method and apparatus applied to a hydrogen gas purification system using a hydrogen storage alloy.
水素吸蔵合金を用いた水素精製装置は近年開発の途にあ
るが、凝縮性ガス、特に水分に関しては特に着目されて
いない。特に発電機内水素ガスに関しては、全く別系統
において脱湿剤（シリカゲル、活性アルミナ等）による
水分分離が行われている。Although hydrogen purification equipment using hydrogen storage alloys has been under development in recent years, no particular attention has been paid to condensable gases, especially moisture. In particular, regarding the hydrogen gas inside the generator, water is separated using a dehumidifying agent (silica gel, activated alumina, etc.) in a completely separate system.
従来の方法及び装置は水素ガス中の水分を除去するに当
り、脱湿剤を充填した塔に水素ガスを通気させている。Conventional methods and devices remove moisture from hydrogen gas by passing the hydrogen gas through a column filled with a desiccant agent.
水素ガス中の水分濃度と脱湿剤中の水分保有率の間にお
いて、平衡関係が′ｈす、水素ガス中の水分濃度が下が
れば、大量の脱湿剤を用いるか、再生操作を頻繁に行う
か、いずれにせよ容易ではない。他の方法及び装置は、
水素ガスを圧縮し、ガス冷却して水分を結露せしめるも
のであるが、圧縮動力を要すること、水素ガスの圧縮に
は危険を伴ない装置は高価であることなど、困難な問題
が多い。There is an equilibrium relationship between the moisture concentration in hydrogen gas and the moisture retention rate in the dehumidifying agent.If the moisture concentration in hydrogen gas decreases, it is necessary to use a large amount of dehumidifying agent or to perform regeneration operations frequently. Either way, it's not easy. Other methods and devices include:
This method compresses hydrogen gas, cools the gas, and causes moisture to condense, but there are many difficult problems, such as the need for compression power and the fact that compressing hydrogen gas is not dangerous and the equipment is expensive.
そこで本発明では、こうした運転維持の繁雑性、コスト
高、危険性などを回避し、水素ガス中の水分を容易に取
除く方法及び装置を提供するものである。Accordingly, the present invention provides a method and apparatus for easily removing moisture from hydrogen gas while avoiding the complexity, high cost, and danger of such operation and maintenance.
本発明においては、水素吸蔵合金を用いた水素の精製は
、合金を充填した容器に粗水素ガスを導びき、水素のみ
を合金に吸蔵させ他のガスを容器内空間に濃縮した後、
空間部ガスを容器外に排出し、ついで合金内に吸蔵され
ている水素のみを取出すことにより、高純度の水素を得
ようというものである。なお、合金への水素の吸蔵時に
は、発熱を伴なうので、容器及び合金を冷却し、水素の
放出時には逆に加熱する。In the present invention, hydrogen purification using a hydrogen storage alloy involves introducing crude hydrogen gas into a container filled with the alloy, storing only hydrogen in the alloy, and concentrating other gases in the space inside the container.
The idea is to obtain high-purity hydrogen by discharging the space gas outside the container and then extracting only the hydrogen stored in the alloy. Note that when hydrogen is absorbed into the alloy, heat is generated, so the container and the alloy are cooled, and when hydrogen is released, they are heated.
こうした操作の中で、粗水素ガス中の凝縮性ガスは吸蔵
時濃縮される段階で、分圧が上がるとともに冷却するこ
とにより凝縮を起こす。During such operations, the condensable gas in the crude hydrogen gas is condensed at the stage where it is concentrated during storage, and the partial pressure increases and the gas is cooled to cause condensation.
方、非凝縮ガスはＩｌ！縮されたガス状態で、容易に系
外に排出される。放出時には容器及び合金は加熱される
ので、凝縮液は蒸発しながら水素とともに放出されてい
くことになる。この時、容器外、精製水素ラインにおい
て冷却すると再び凝縮性ガスは凝縮し、水素より分離さ
れる。On the other hand, the non-condensable gas is Il! It is easily discharged from the system in a compressed gas state. Since the container and the alloy are heated during discharge, the condensate is evaporated and discharged together with the hydrogen. At this time, when it is cooled outside the container in the purified hydrogen line, the condensable gas condenses again and is separated from the hydrogen.
水素吸蔵合金を用いた水素精製システムにおいて、水素
以外のガスは合金容器内空間部に濃縮されるが、特に凝
縮性ガスは分圧の上昇と冷却により、容器内において凝
縮する。In a hydrogen purification system using a hydrogen storage alloy, gases other than hydrogen are concentrated in the inner space of the alloy container, and in particular, condensable gases are condensed in the container due to an increase in partial pressure and cooling.
先づ、非凝縮性ガスを排出波、合金より水素を放出させ
るが、加熱により凝縮液が蒸発し、水素とともに取出さ
れる。この時、凝縮成分は大部分が、水素ガス中に飽和
の状態で、放出初期において放出される。従って、放出
水素ガスを容器外において冷却することにより、凝縮成
分を分離除去することができる。First, the non-condensable gas is discharged and hydrogen is released from the alloy, but the condensate is evaporated by heating and taken out together with the hydrogen. At this time, most of the condensed components are saturated in hydrogen gas and are released at the initial stage of release. Therefore, by cooling the released hydrogen gas outside the container, the condensed components can be separated and removed.
即ち、粗水素ガスは、高純度水素、非凝縮性ガス及び＃
縮性ガスの凝縮液の３つの区分に分離される。That is, crude hydrogen gas includes high purity hydrogen, non-condensable gas and #
The condensate of the condensable gas is separated into three sections.
本発明の実施例を以下図面に従って詳細に説明する。 Embodiments of the present invention will be described in detail below with reference to the drawings.

In addition to hydrogen, it contains non-condensable gases such as nitrogen, oxygen, and carbon dioxide, as well as moisture as condensable gases. The temperature was room temperature and the pressure was 4 atm.

を開けて合金内の水素を取出すが。When the hydrogen introduction valve 8 is opened and crude hydrogen is introduced into the cooled container, hydrogen is stored in the alloy 1 and other gases are concentrated between the alloy particles, but water, which is a condensable gas, condenses and becomes liquid. becomes. After sufficient hydrogen has been introduced, the switching valve 12a is closed, the switching valve 129 is opened, and the non-condensable gas between the alloy grains is discharged to the atmosphere from the non-condensable gas discharge pipe 9. Next, the switching valve 12b is closed, the container is switched to heating, and the switching valve 1'2c is closed.
Open it and take out the hydrogen inside the alloy.

発電機に戻す。The condensed water evaporates due to heating and comes out together with hydrogen, so a re-condenser 13 is inserted into this line to re-condense it, and it is taken out as a condensate from the condensate extraction pipe 11.
High purity hydrogen is extracted from the purified hydrogen extraction pipe 1°,

を通す必要はない。The hydrogen purity introduced is 99.9% (dry), and the water content is 1. It is about OOppm. The concentration ratio of non-condensable gas in the container is 100 times, and the concentration ratio of water is 100 times.
OOppm, most of which is condensed. At a release temperature of 80° C., saturated water is accompanied at the beginning of hydrogen release, and the water concentration is extremely high (reaching well over several dozen). When this is cooled to 5°C in the recondenser 13, the water concentration becomes 1
The difference is condensed. During the release ridge stage, the water in the released hydrogen is almost gone, so the recondenser 13
There is no need to go through it.
