It is an important dehydrating agent, good humectant and an industrial solvent.Storage and handlingMEG is stored and shipped in stainless steel tanks (or in ordinary steel drums/tanks with epoxy resin coating) to avoid iron contamination.PackagingMEG is loaded after thorough cleaning and drying of tanks and nitrogen purging to ensure that it remains chloride, iron, and ash-free. Shipments are made in tanks.
