Description

Znane sa dzialania elektroosmotyczne na mieszaniny zawierajace zawiesiny cial stalych w osrodku wodnym. Ta droga moz¬ na zapomoca pradu elektrycznego przepro¬ wadzic osadzenia delikatnych zawiesin glinki w wodzie,, albo oddzielenie wody z torfu i tym podobnych mieszanin. Jezeli jednak chodzi o osadzenia cial stalych, za¬ wartych w postaci zawiesin lub roztworu koloidalnego w cieczach niemieszajacych sie z woda, których przewodnictwo prak¬ tycznie równa sie zeru, wówczas elektro- osmoza nie daje sie bezposrednio zastoso¬ wac.Opisany wynalazek sluzy do wydziela¬ nia takich dal stalych z cieczy nieprzewo- dzacych pradu elektrycznego, a nie mie¬ szajacych sie z roztworami wodnemi, a wiec, np. do wydzielenia drobno-krysta- licznej parafiny z destylatów ropy nafto¬ wej, lub koloidalnych zawiesin asfaltu z ropy naftowej,, jej destylatów albo pozo¬ stalosci destylacyjnych i tym podobnych.Doswiadczenia wykazaly mianowicie, ze jezeli takie ciecze zostana zadane malemi ilosciami odpowiednich niewodnych sub- stancyj, wytwarzajacych jony w tych cie¬ czach, a wiec, np. pewnemi kwasami orga-nicznemi, jak octowym, lub roztworami al- koholowemi, eterowemi i t. d. pewnych zwiazków, a to np. wodorotlenku potaso¬ wego, chlorku cynkowego i innemi sub¬ stancjami jonizujacemi sie w roztworach bezwodnych, to wówczas dzialanie elektro- osmotyczne, przy uzyciu nawet niezbyt wy¬ sokich napiec pradu stalego, nie przewyz¬ szajacych 1000 Volt, daje dobre rezultaty* Dzieki temu wynalazkowi mozna wydzie¬ lac z trudno filtrujacego sie oleju parafino¬ wego krysztaly parafiny w postaci zbitej masy. Podobnie mozna osiagnac wydziele¬ nie asfaltu z ropy naftowej. PLThere are known electroosmotic effects on mixtures containing suspensions of solids in an aqueous medium. This way, an electric current can be used to settle fine clay suspensions in the water, or to separate the water from peat and similar mixtures. However, when it comes to the deposition of solids contained in the form of suspensions or colloidal liquids in water-immiscible liquids, the conductivity of which is practically zero, then electrosmosis cannot be directly applied. Such solids from liquids which do not conduct electricity and are not miscible with aqueous solutions, i.e. for the separation of fine-crystalline paraffin from petroleum distillates or colloidal suspensions of asphalt from crude oil , its distillates or distillation residues and the like. Experience has shown that, if such liquids are administered with small amounts of suitable non-aqueous substances, which generate ions in these liquids, i.e. with certain organic acids, such as acetic or alcoholic solutions, ethers, etc. of certain compounds, such as potassium hydroxide, zinc chloride and other ionizing substances and in anhydrous solutions, then the electro-osmotic action, using even not very high DC voltages, not exceeding 1000 Volt, gives good results. Thanks to this invention, it is possible to separate the hard-to-filter paraffin oil from paraffin crystals in the form of a compact mass. Likewise, it is possible to separate the asphalt from the petroleum. PL
