Description

przewodach gazowych koksu.Przy przeplukiwaniu zbiorników i prze¬ wodów gazowych woda, amon jakiem lub podobna ciecza przeprowadza sie ciecz w obiegu kolowym, przyczem po uplywie pewnego czasu ciecz ta nasyca sie amon ja¬ kiem i innemi skladnikami, zawartemi w gazie. Sposób ten posiada jednak te wade, ze otrzymana smola jest bardzo gesta i za¬ wiera bardzo wielkie ilosci wody amonja¬ kalnej, a destylacja jej jest bardzo trudna, poniewaz z powodu naglego wzburzania sie powstaja wybuchy i pozary. Oprócz te¬ go wytwarzaja sie w rurach, w których smola styka sie z gazami, geste jej osady i pak, rury te musza wiec byc ciagle oczy¬ szczane.Celem zapobiegania tym wadom, do¬ prowadzano do zbiornika odrebne ilosci smoly, które rozpuszczaly osady geste i u- mozliwialy w ten sposób ich wydzielanie.Równiez osiagano wieksza plynnosc gestej smoly zapomoca domieszki olejów lekkich.Sposoby te usuwaja wprawdzie niepoza¬ dane nastepstwa zgeszczania sie smoly, nie usuwaja jednak powodów tej wady.Próby wykazaly, ze powodem tych wad jest zbyt wielkie zwiekszanie sie zawarto¬ sci amon jaku w wodzie amonjakalnej, slu¬ zacej do przeplókiwania przewodów, a mianowicie zawartosc amon jaku w wodzie amonjakalnej wzrasta np. powyzej 15 g na litr. Ciezar gatunkowy cieczy zwiekszasie wraz ze zwyzka zawartosci amon jaku, stracajacego sie w postaci soli polaczonych z chlor&m* i zMizA* sie ?do ciezaru gatunko¬ wego smoly. Oddzielanie smoly od cieczy staje sie wiec niezupelne, a powstajaca smola zawiera wielkie ilosci wody, która nie moze byc z niej latwo wydzielona. Wo¬ da amonjakalna zawiera smole, jest nie¬ czysta, a przeróbka jej jest trudna, ponie¬ waz oba te materjaly sa tak dokladnie ze soba zmieszane, ze powstaje zawiesina, która utrudnia oddzielenie smoly od wody.Powodem zgeszczania smoly jest równiez stracanie stalych soli amoniakalnych, po¬ wstajacych trzy wzrastajacej zawartosci amon jaku tak, iz wytwarza sie trudno roz¬ puszczalna masa smolowa. Wielkie zge- szczanie zwiazków amoniaku i siarki po¬ woduje czesciowa pollmeryzacie smoly, zgeszczenia jej wzrastaja wiec do takiego stopnia, iz usuwanie ich z urzadzenia jest bardzo trudne.Wynalazek niniejszy omija te wady w ten sposób, iz do cieczy plóczacej zosta¬ je doprowadzana odpowiednia ilosc roz¬ cienczonej wody amonjakalnej, np. kon¬ densatu pierwszych chlodnic, lub swiezej wody w celu powstrzymania wzrostu za¬ wartosci amon jaku w cieczy, przyczem ilosc doprowadzanej wody reguluje sie tak by ta zawartosc amon jaku nie przekraczala 15 g na litr. Smola wytworzona pozosta¬ je wiec plynna i zawiera male ilosci wody, moze wiec byc latwo oddzielona od wody amonjakalnej. Woda ta jest czysta i latwo- plynna, przeróbka jej na zwiazki amon ja¬ ku jest wiec latwa. Zaleta wynalazku ni¬ niejszego polega wiec na tern, ze zarówno smola jak tez woda amonjakalna nie two¬ rza zawiesin, dzieki czemu obydwa te skladniki moga byc latwo oddzielone jeden od drugiego, co zapobiega stratom na ma- terjale i nie wymaga wielkich urzadzen, sluzacych do oddzielenia smoly od wody amonjakalnej. PLIn the case of flushing the tanks and gas lines, water, ammonium or a similar liquid passes a liquid in a circular cycle, and after some time this liquid becomes saturated with ammonium and other constituents contained in the gas. However, this method has the disadvantage that the tar obtained is very dense and contains very large amounts of ammoniacal water, and its distillation is very difficult, since explosions and fires occur due to sudden agitation. In addition, thick deposits and pitch are produced in the pipes in which the tar is in contact with the gases, so these pipes must be constantly cleaned. In order to prevent these drawbacks, separate amounts of tar were fed to the tank, which dissolve the deposits. dense and enabled their separation. A greater fluidity of the thick tar was also achieved by the admixture of light oils. Although these methods remove the undesirable consequences of tar caking, they do not remove the reasons for this defect. Attempts have shown that the reason for these defects is too a great increase in the ammonium content of the ammoniacal water used for flushing the conduits, namely the ammonium content of the ammonia water increases, for example, above 15 g per liter. The specific weight of the liquid increases with the increase in the content of ammonium yak, which is lost in the form of salts combined with chlorine & m * and changes to the specific weight of the tar. Thus, the separation of tar from the liquid becomes incomplete and the resulting tar contains large amounts of water that cannot be easily separated from it. Ammoniacal water contains tar, it is impure, and it is difficult to process it, because the two materials are so intimately mixed with each other that a slurry is formed which makes it difficult to separate the tar from the water. ammoniacal compounds, resulting in three increasing amounts of ammonium, such that a hardly soluble tar is produced. The great condensation of ammonia and sulfur compounds causes a partial pollmerization of the tar, so that its compaction increases to such an extent that removing them from the device is very difficult. The present invention avoids these disadvantages in such a way that an appropriate the amount of dilute ammonia water, eg condensate of the first coolers, or fresh water to suppress the increase in the ammonium content of the liquid, while the amount of water supplied is adjusted so that the ammonium content does not exceed 15 g per liter. The tar produced thus remains liquid and contains a small amount of water, and can therefore be easily separated from the ammoniacal water. This water is clean and easy to fluid, so it is easy to convert it into ammonium compounds. The advantage of the present invention is therefore that neither the tar nor the ammoniacal water form suspensions, so that both of these components can be easily separated from one another, which prevents material losses and does not require large equipment for to separate tar from ammoniacal water.
