Abstract

The removal of moisture from gases is carried out by adsorption to a composition which comprises an active metallic component, preferably chromium, on a heat-resistant oxidic support. The absorption of moisture is connected with a colour change of the composition which can be used as an indicator when a transparent adsorption cartridge is employed.

Description

SPÔSOB ODSTRAŇOVANIA VLHKOSTI Z PLYNOV A PATRÓNA NA JEHO VYKONÁVANIEA METHOD FOR REMOVING THE MOISTURE FROM GASES AND THE PATRON FOR ITS IMPLEMENTATION

Oblasť technikyTechnical field

Vynález sa týka spôsobu odstránenia vlhkosti z plynov vedením plynov adsorpčným činidlom pohlcujúcim vlhkosť a patróny na jeho vykonávanie.The invention relates to a process for removing moisture from gases by conducting the gases with a moisture-absorbing adsorbent and cartridges for carrying out the process.

Doterajší stav technikyBACKGROUND OF THE INVENTION

Dlho je známe sušenie plynov použitím chemikálií pohlcujúcich vlhkosť.It has long been known to dry gases using moisture-absorbing chemicals.

Vzrastá však záujem, obzvlášť pri sušení inertných a vzácnych plynov, ozrejmiť tiež zachytenie vlhkosti použitou chemikáliou.However, there is an increasing interest, in particular when drying inert and noble gases, to clarify the entrapment of moisture by the chemical used.

Podstata vynálezuSUMMARY OF THE INVENTION

Vynález spočíva v úlohe vytvoriť spôsob oddelenia vlhkosti z plynov pomocou adsorpčného činidla, ktoré jednak odstraňuje až do stopového obsahu vlhkosť, jednak spoľahlivo oznamuje » zachytenie vlhkosti adsorpčným prostriedkom.SUMMARY OF THE INVENTION The object of the present invention is to provide a method of separating moisture from gases by means of an adsorption agent which removes moisture up to the trace content and reliably reports the entrapment of moisture by the adsorbent.

• Vzhľadom k stavu techniky uvedenému v predvýznakovej časti hlavného nároku je táto úloha vyriešená znakmi uvedenými vo význakovej časti nároku 1, ktoré spočívajú v tom, že sa adsorpčné činidlo, ktoré pozostáva z aktívnych komponentov obsahujúcich železo, nikel, rénium, hlavne titan, mangán, vanád, molybdén a/alebo chróm, umiestnených na tepelne odolnom oxidickom nosiči s veľkým povrchom aktivuje pri aktivačnej teplote 300 až 600 °C molekulárnym kyslíkom a následne sa na neho pri teplote medzi 200 C a aktivačnou teplotou pôsobí redukčným plynom.In view of the state of the art mentioned in the preamble of the main claim, this object is achieved by the features set forth in the characterizing part of claim 1, characterized in that the adsorption agent consists of active components comprising iron, nickel, rhenium, especially titanium, manganese, Vanadium, molybdenum and / or chromium, placed on a heat-resistant, large-surface oxide carrier, is activated with molecular oxygen at an activation temperature of 300 to 600 ° C and subsequently treated with a reducing gas at a temperature between 200 ° C and the activation temperature.

Výhodné vyhotovenia vynálezu sú uvedené vo vedľajších nárokoch.Preferred embodiments of the invention are set forth in the subclaims.

Adsorpčný prostriedok použitý pri postupe podľa vynálezu je známy z DE-PS 16 67 129. Látka popísaná v tomto patentovom spise slúži prevažne na odstránenie reakčných prímesi z plynov a tekutín. Pri odstránení kyslíka je obzvlášť účinné, keď je nosný materiál obložený komponentmi obsahujúcimi chróm. Je prekvapujúce, že sa môže touto látkou za vzniku zretelného zafarbenia velmi účinne odstrániť z plynov tiež voda. Tak . napríklad látka obsahujúca chróm má v stave bez zachytenej vlhkosti modrú farbu. Pri zachytení vlhkosti nastáva zmena farby na fialovo červenú.The adsorption agent used in the process according to the invention is known from DE-PS 16 67 129. The substance described in this patent is mainly intended to remove reaction impurities from gases and liquids. The removal of oxygen is particularly effective when the support material is lined with chromium-containing components. It is surprising that water can also be very efficiently removed from the gases by producing this clear color. So. for example, the chromium-containing substance is blue in the moisture-free state. When moisture is captured, the color changes to violet-red.

Pre spôsob podlá vynálezu sa prednostne používajú priehladné patróny, ktoré sú naplnené adsorpčným činidlom. Patróny potom obsahujú samočinne sa uvolňujúce adsorbenty vlhkosti. K adsorpčnému činidlu sa tiež môžu ako indikátory farby primiešať iné adsorbenty vlhkosti.For the process according to the invention, transparent cartridges are used which are filled with an adsorbent. The cartridges then contain self-releasing moisture adsorbents. Other moisture adsorbents may also be admixed with the adsorbent as color indicators.

Príklady vyhotovenia vynálezuDETAILED DESCRIPTION OF THE INVENTION

Vysokú účinnosť spôsobu v nasledujúcom popísaný príklad.High process efficiency in the example described below.

podlá vynálezu ukazuje Ako adsorpčné činidlo bola použitá látka obsahujúca chróm so silikagélom ako nosným materiálom. Priehľadnou patrónou naplnenou týmto adsorpčným prostriedkom sa vedie inertný plyn, ktorý obsahuje stopy vodnej Pary.According to the invention, a chromium-containing substance with silica gel as carrier material was used as the adsorbent. An inert gas containing traces of water vapor is passed through a transparent cartridge filled with this adsorbent.

Od zavedenia patróny sa postupne farbil najprv modrý adsorpčný prostriedok na fialovo červenú. Za patrónou sa kontrolovala za pomoci hygrometra vlhkosť. Keď hranica zafarbenia dosahovala konce patróny, bol súčasne registrovaný zlom vlhkosti. Pritom sa ukazuje, že experimentálne zistená kapacita vlhkosti je takmer zhodná so silikagélom použitým ako nosný materiál.Since introduction of the cartridge, the blue adsorbent has been progressively stained to violet-red. Behind the cartridge, moisture was checked using a hygrometer. When the color boundary reached the end of the cartridge, a moisture break was also registered. The experimentally determined moisture capacity is shown to be almost identical to the silica gel used as the carrier material.
