Absorboivan massan käyttö vesihöyryn poistamiseksi kaasuistaUse of absorbent mass to remove water vapor from gases
Keksintö koskee patenttivaatimuksen 1 lajimääritelmän mukaista, jul-5 kaisusta DE-B 1 667 129 tunnetun massan käyttöä kosteuden poistamiseksi kaasuista.The invention relates to the use of a pulp known from DE-B 1 667 129 according to the species definition of claim 1 for removing moisture from gases.
Kaasujen kuivaaminen käyttämällä kosteutta vastaanottavia kemikaaleja on hyvin tunnettua. Käytettävien kemikaalien kosteudella kuormittumisen tekeminen myös näkyväksi on kuitenkin kasvavan kiinnostuksen kohteena, 10 erityisesti inertti- ja jalokaasujen kuivauksen yhteydessä.Drying of gases using moisture-absorbing chemicals is well known. However, increasing the visibility of the moisture content of the chemicals used is also of increasing interest, particularly in the drying of inert and noble gases.
Keksinnön päämääränä on siten saada aikaan menetelmä kosteuden poistamiseksi kaasuista adsorbointiaineiden avulla, joka toisaalta vähentää kosteuden hyvin alhaiselle pitoisuusalueelle ja toisaalta osoittaa tarkasti adsor-bointiaineen kuormittumisen kosteudella.The object of the invention is thus to provide a method for removing moisture from gases by means of adsorbents which, on the one hand, reduces the moisture to a very low concentration range and, on the other hand, accurately indicates the moisture loading of the adsorbent.
15 Lähtien patenttivaatimuksen 1 lajimääritelmän mukaisesta tekniikan tasosta päämäärään päästään keksinnön mukaisesti patenttivaatimuksen 1 tun-nusmerkkiosassa esitetyin tunnusmerkein.From the state of the art according to the species definition of claim 1, the object is achieved according to the invention by the features set forth in the characterizing part of claim 1.
Keksinnön edullisia lisäsuoritusmuotoja esitetään alivaatimuksissa.Preferred further embodiments of the invention are set forth in the subclaims.
Keksinnön mukaiseen menetelmään käytettävää adsorbointiainetta 20 kuvataan DE-patenttijulkaisussa 1 667 129. Kyseisessä patenttijulkaisussa kuvattu massa poistaa etupäässä reaktiivisia epäpuhtauksia kaasuista ja nesteis-tä. Se on erityisen tehokasta hapen poistamisessa, kun kantajamateriaali on :1 kuormitettu kromipitoisilla komponenteilla. On yllättävää, että tällä massalla voi- daan poistaa hyvin tehokkaasti myös vettä kaasuista, jolloin tapahtuu selvä vä-:. 25 rinmuutos. Niinpä esimerkiksi kromipitoinen massa on kuormittamattomana si- ”‘J nistä väriltään. Kosteudella kuormittumisen yhteydessä tapahtuu värin muuttu- '; minen punaiseksi-sinipunaiseksi.The adsorbent 20 for use in the process of the invention is described in DE-A-1 667 129. The pulp described in that patent predominantly removes reactive impurities from gases and liquids. It is particularly effective at removing oxygen when the carrier material is: 1 loaded with chromium containing components. It is surprising that this mass can also very effectively remove water from the gases, whereby a clear color occurs. 25 Bias change. Thus, for example, the chromium-containing mass is unloaded in color. When exposed to moisture, a color change occurs; red-blue-red.
I f · v Keksinnön mukaisessa käytössä käytetään edullisesti läpinäkyviä patruunoita, jotka on täytetty adsorbointiaineella. Patruuna sisältää tällöin itse-30 näyttävää kosteutta adsorboivaa ainetta. Adsorbointiainetta voidaan kuitenkin sekoittaa myös muihin kosteutta adsorboiviin aineisiin väri-indikaattoriksi.In use according to the invention, transparent cartridges filled with adsorbent are preferably used. The cartridge itself contains 30 impressive moisture adsorbents. However, the adsorbent can also be mixed with other moisture adsorbents as a color indicator.
.·. Seuraavaksi kuvattava koe-esimerkki osoittaa keksinnön mukaisen menetelmän suuren tehon. Adsorbointiaineena käytettiin kromipitoista massaa, jonka kantajana oli silikageeli. Tällä adsorbointiaineella täytetyn läpinäkyvän pat- > : : 35 ruunan läpi johdettiin inerttikaasua, joka sisälsi pieniä määriä vesihöyryä ; · (50 ppm ja 3 ppm). Aluksi sininen adsorbointiaine värjäytyi patruunaan sisääntu- 2 113628 lopäästä alkaen etenevällä tavalla punaiseksi-sinipunaiseksi. Kosteuspitoisuutta patruunan ulosmenopuolella seurattiin kosteusmittarilla. Kun väriraja saavutti patruunan ulosmenon, rekisteröitiin samanaikaisesti kosteuden läpitulo. Tällöin osoittautui, että kokeellisesti määritetty kosteuskapasiteetti on lähes sama kuin 5 kantajamateriaalina käytetyn silikageelin. 1 »· • ·. ·. The following test example demonstrates the high efficiency of the method of the invention. The adsorbent was a chromium-containing mass supported on silica gel. A transparent pat->:: 35 edge filled with this adsorbent was passed through an inert gas containing small amounts of water vapor; · (50 ppm and 3 ppm). Initially, the blue adsorbent was colored red to blue-red from the end of the cartridge into the cartridge at 113628. The moisture content at the outlet of the cartridge was monitored with a humidity meter. When the color limit reached the cartridge outlet, moisture penetration was simultaneously recorded. It was then found that the moisture capacity experimentally determined was almost the same as the silica gel used as carrier material. 1 »· • ·
