Abstract

Inventia se refera la un procedeu de îndepartare a urmelor de gudron acid din uleiul de transformator rafinat, conform caruia, urmele de gudron acid existente în uleiul rafinat si separat prin centrifugare, sunt coagulate prin tratare cu acid sulfuric de concentratie 50...52%, în proportie de 10% greutate fata de ulei, sub agitare cu aer tuimp de 30 min, dupa care se lasa uleiul la separare timp de 2...3h, apoi se scurge acidul diluat separat, care se refoloseste pentru urmatoarea sarja de ulei; urmele de gudron acid coagulate sunt îndepartate, iar uleiul este supus apoi tehnologiei obsnuite de finisare.The invention relates to a process for removing acid tar traces from refined transformer oil, according to which the acid tar traces present in the refined oil and separated by centrifugation are coagulated by treatment with sulfuric acid at a concentration of 50 ... 52% , 10% by weight of oil, stirring with thimp for 30 minutes, then allowing the oil to separate for 2 to 3 hours, then draining the diluted diluted acid which is re-used for the next oil batch ; the traces of coagulated acid tar are removed and the oil is then subjected to the usual finishing technology.
