Abstrakt: The article discusses the benefits of polyvinyl alcohol (PVA) size recovery and reuse in terms of the environment, energy and economy, with the use of vacuum flash evaporation (VFE) process. In this technology, the excess water in the dilute PVA desize stream is vacuum flash evaporated in a controlled pressure manner. All of the water contained in the desize stream is recovered and recycled back into a plant, giving a closed-loop character to the overall desizing-size recovery/concentration-reuse sequence of processes and aiding the overall economics. VFE helps minimize water pollution, energy and water consumption in textile industry, thereby contributing to a greener world.
