PROCESS FOR ACTIVATING AND REVIVING ORDERED PHOSPHOR-BRONZE FILLINGS

The invention relates to a process for activating and reviving ordered fillings made of phosphor-bronze mesh, applicable to the distillation columns. According to the invention, the process comprises the following steps: degreasing the filling by washing with an acetone-ethyl alcohol-toluen mixture, from the top to the bottom of the column for 3 hours, followed by washing with demineralized water from bottom to top, by filling the column and chemically treating with a hydrogen dioxide solution, carried out by immersing the filling into a 8 % hydrogen dioxide solution, with the continuous circulation of the solution from the bottom to the top until lowering the hydrogen dioxide content in the solution below 0.1 %, followed by washing with demineralized water from the top to the bottom, all the operations being carrried out directly inside the distillation columns. Inventia se refera la un procedeu de activare si reactivare a umpluturilor ordonate, confectionate din plasa metalica de bronz fosforos, utilizate la coloanele de distilare. Procedeul conform inventiei cuprinde urmatoarele etape: degresarea umpluturii printr-o spalare cu un amestec de acetona - alcool etilic - toluen, de la varful coloanei spre baza, timp de 3 h, dupa care urmeaza o spalare cu apa demineralizata; de jos in sus, prin umplerea coloanei si tratarea chimica cu o solutie de apa oxigenata, ce se realizeaza prin imersarea umpluturii intr-o solutie de 8% apa oxigenata, si cu o circulatie continua a solutiei de jos in sus, pana cand continutul apei oxigenate in solutie scade sub 0,1%, dupa care urmeaza o spalare descendenta cu apademineralizata, toate operatiile realizandu-se direct in coloanele de distilare.
