At Zvijezda, Croatia’s largest producer of edible oils, overheated steam is needed in the process of oil refining and margarine production. Sudden chilling transforms steam to water condensate. Previously the condensate was wasted, thus wasting water and heat. With improvement of the process this condensate is pumped back into heating facility, slightly heated and returned back to process. In this way water as well as heat is re-used. Savings are approximately €80,000 on annual basis.
