Zusammenfassung:FIELD: petroleum processing and disposal of waste. ^ SUBSTANCE: acid sludge is heated and water is electrochemically stripped, after which acid sludge is neutralized and then oxidized with air oxygen. Neutralization and oxidation are performed also using electrochemical technique, while heating of acid sludge, stripping of water, neutralization, and oxidation are carried out on the same apparatus. ^ EFFECT: reduced production time and improved quality of bitumen. ^ 1 tbl, 2 ex
