JEFFTREAT® MS-205 LFG

JEFFTREAT® MS-205 LFG is a solvent in the JEFFTREAT® MS-200 series, a clear, water-white, hygroscopic liquid with an ammoniacal odor. Based on methyldiethanolamine (MDEA), it is formulated for the bulk removal of hydrogen sulfide and carbon dioxide from gas and gas-liquid streams. Suitable for natural gases, refinery gases, coal and waste gasification gases, and petrochemical gases, this solvent offers a cost-effective alternative to traditional primary and secondary alkanolamines like monoethanolamine (MEA) and diethanolamine (DEA). JEFFTREAT® MS-200 series solvents are effective in meeting low carbon dioxide specifications even in the presence of significant hydrogen sulfide.

    Storage & Handling

    Storage and Handling Information
    • The handling and storage of JEFFTREAT® solvents present no unusual problems.
    • The solvent 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® elastomer, neoprene, and nitrile as these materials tend to swell when exposed to the amine. KALREZ® 1050LF elastomer performs satisfactorily in amine service as well as materials made from polypropylene and TEFLON® elastomer.
    • 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® gaskets work well for flanged connections.
    • For pumps, a Durametallic Type RO-TT mechanical seal or equivalent is suitable.
       
    Shelf Life Information

    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.
