ABSTRACT:
A mobile process to reclaim spent aqueous glycol solutions used as heat transfer fluids and which contains deleterious contaminants, oil/grease, corrosion products, and additives such as buffers and corrosion inhibitors. Particulate contaminates and oil/grease are removed by passing the solution through an ultrafiltration membrane. The dissolved contaminants are removed by passing through a series of ion exchange resin (IER) vessels. The reclaimed glycol solution is reused after replacing the required additives. One embodiment provides for central processing of the filtration and absorption media housed in a mobile enclosure, such as a trailer. The mobile trailer may be used at various collection sites for cleaning and reprocessing spent glycols. After the media are spent, the mobile trailer is returned to a central processing facility for regeneration of the filtration and absorption media. The waste produced by the regeneration is concentrated at a single treatment and disposal facility.
