Abstract
Inventia se refera la un procedeu electrochimic de îndepartare a produsilor de coroziune de pe oteluri, prin dizolvare în solutii tampon complexante concentrate compuse din acid clorhidric, citrat disodic si inhibitor sau acid citric, citrat disodic si inhibitor, în domeniul de pH cuprins între 2 si 5, la temperatura între 50 si 90 degree C, sub protectie catodica. Procedeul poate fi utilizat la decontaminarea componentelor circuitului primar al centralelor nuclearo-energetice de tip PWR si PHWR, la decaparea otelurilor carbon si la îndepartarea produsilor de coroziune de pe componentele din otel carbon din termocentralele clasice.
