1. Type of technology Physical adsorption on activated carbon. 2. Contaminants which can be removed Volatile organic compounds (VOC), the above plant is particularly suitable for cleaning air containing just one solvent. 3. Emission limits possible When suitably dimensioned, collection efficiencies of 99% are obtained. 4. Description of the equipment and/or process “ To ensure a future, we must not destroy. Use solvents and recover them thus avoid waste and search for products and alternative systems at the expense of quality and with high costs”. With this slogan dating well back to the early 1980’s when Ventilazione Industriale Srl was turning towards solvent recovery plants with steam stripping, the company wished to attract the attention of many industrial sectors including printers on paper, metal and plastic film, distilleries, paper mills, foundries, plastic coating firms etc. by informing them that it is now possible to make use of a pilot plant to define with a high degree of accuracy what should be the process and optimum running conditions to best optimize the proposed investment. Moreover the use of such plant is in line with the ecological requirements of the society in which we live, because besides guaranteeing a very certain saving in money, it allows full cleaning of the air saturated with solvent and removal of obnoxious odours emitted in the atmosphere. 4.1 Principle of operation There are 4 main phases in a solvent recovery process, namely: A. separation of the solvent from the air by adsorption on activated carbon B. desorption through steam C. separation of the solvent from the water by dehydrating the hydrated solvent
