MPG is transported by tank truck and vessel as bulk and packaged (drums, intermediate bulk containers (IBC) products. The MPG USP grade needs specific attention regarding product quality and purity. Therefore, dedicated equipment and specific cleaning procedures as well as stringent controls throughout the whole supply chain are necessary. MPG is hygroscopic and requires storage equipped with drying devices to protect the product from humidity. Nitrogen blanketing compatible to USP requirements is the preferred means of keeping the product dry and ensuring its shelf life. Storage temperature should not exceed 104°F /40°C and the product should not be stored in direct sunlight. In cold climates, tank heating devices and insulation must be installed.
