Description
Przy wydobywaniu przez czesciowe skroplenie wodoru z mieszanin np. gazów pieców koksowych, czesto zauwazone nie- regularnosci przypisywano acetylenowi i innym cialom zblizonym pod wzgledem sprezystosci pary. Jezeli acetylen znajdu¬ je sie w stosunku bardzo slabym wzgled¬ nie do etylenu bedacego w nadmiarze, roz¬ puszcza sie zupelnie w etylenie przy spo¬ sobie wskazanym w patencie francuskim Nr 585 996 pod tytulem: „Sposób wstepne¬ go wydobywania etylenu, a za jego pomo¬ ca usuwania pewnych zanieczyszczen przy rozdziale przez skraplanie gazów z pieców koksowych i im analogicznych".Jezeli jednak zawartosc etylenu jest bardzo nieznaczna, moze sie zdarzyc, ze niewielkie ilosci acetylenu, odpowiadajace nadzwyczaj slabej preznosci pary, nie u- legaja dzialaniu rozpuszczajacemu, prze¬ chodza przez wymienniki i dostaja sie do przyrzadu separujacego, a znalazlszy sie w nim w postaci stalej, po pewnym czasie moga powodowac przeszkody.Przedstawiony wynalazek rozwiazuje te trudnosc przez zuzytkowanie duzej roz¬ puszczalnosci acetylenu w plynnym etyle¬ nie. Zasada polega na zwiekszeniu az do granic dostatecznych zawartosci etylenu w traktowanych gazach, dodajac do nich odpowiednia ilosc etylenu, otrzymanego wedlug powyzej wskazanego patentu i po-zbawionego uprzednio zapomoca rektyfi¬ kacji lub innego odpowiedniego sposobu chemicznego wiekszej czesci acety¬ lenu.Zawdzieczajac temu dodatkom/i pracuje sie stale w warunkach sprzyjajacych, po¬ wyzej wskazanych, a wahania zawartosci gazów piecowych okazuja sie bez wplywu.Poniewaz ten proces odbywa sie w obiegu zamknietym, przy stalej ilosci etylenu do¬ datkowego, niema istotnego zuzycia tego ciala. Jedynym dodatkowym rozchodem jest energja konieczna do sprezania doda¬ wanego etylenu, ale w kazdym razie jest ona znikoma, gdyz dodatek nie przenosi wogóle 5% objetosci traktowanych gazów piecowych. PLIn the case of extraction by partial condensation of hydrogen from mixtures of, for example, coke oven gases, the observed irregularities were often attributed to acetylene and other bodies related to the vapor pressure. If the acetylene is in a very weak ratio with respect to ethylene in excess, it dissolves completely in ethylene in the manner described in French Patent No. 585,996 under the title: "Method for the preliminary extraction of ethylene, and it helps to remove certain contaminants when separating gases from coke ovens and the like by condensation. "However, if the ethylene content is very small, it may be that small amounts of acetylene, corresponding to an extremely poor vapor pressure, do not have a dissolving effect, They pass through the exchangers and enter the separating device, and once in solid form, they can cause obstacles after some time. The present invention solves this problem by using a high solubility of acetylene in liquid ethylene. The principle is to increase up to the limit of sufficient ethylene content in the treated gases, adding the appropriate amount of ethylene to them, obtain Due to the above-mentioned patent and previously free from rectification or other suitable chemical method, the greater part of acetylene is due to these additives / and works constantly under favorable conditions, as indicated above, and fluctuations in the content of furnace gases turn out to be without Since this process takes place in a closed circuit, with a constant amount of additional ethylene, there is no significant wear of this body. The only additional expenditure is the energy required to compress the added ethylene, but in any case it is negligible as the additive does not transfer at all 5% of the volume of the furnace gases treated.
