JEFFTREAT® MS 300 is a specially formulated gas-treating solvent based on methyl diethanolamine (MDEA). This clear, water-white, hygroscopic liquid with an ammoniacal odor is designed to efficiently address gas treatment needs. One notable advantage of using This product is its potential to allow operators to shut down the incinerator for off-gas, potentially leading to substantial cost savings. Additionally, this solvent has a clear to slightly hazy appearance and is substantially free of foreign matter, ensuring its suitability for various industrial applications.

    Storage & Handling

    Storage and Shelf Life Conditions
    • The product should retain its conformance to sales specifications for a period of at least two years after date of manufacture if the product is stored at less than 100°F in its undamaged, unopened, factory packaged container.
    • In general, the user should determine the suitability of any chemical compound, no matter what the shelf life or length of time of storage. Each user should conduct a sufficient investigation to establish the suitability of any product for his intended use.
    • The handling and storage of JEFFTREAT® solvents present no unusual problems.
    • The properties and alkaline nature of JEFFTREAT® solvents should be considered when choosing materials of construction.
    • JEFFTREAT® solvents should not be stored in tanks made from zinc, galvanized steel, or copper and its alloys since the solvent will react with copper to form complex salts.
    • Also avoid the use of elastomers such as Buna N, VITON®1, neoprene, and nitrile as these materials tend to swell when exposed to the amine.
    • KALREZ®1 1050 LF performs satisfactorily in amine service as well as materials made from polypropylene and TEFLON®1.
    • A carbon steel storage tank, constructed according to a recognized code, is generally satisfactory.
    • Carbon steel transfer lines, joined by welds or flanges, are suitable.
    • Screw joints are subject to failure unless back-welded. FLEXITALLIC®2 gaskets work well for flanged connections.
    • For pumps, a Durametallic Type RO-TT mechanical seal or equivalent is suitable.
