JEFFTREAT® MS100 is a clear, water-white, hygroscopic liquid with an ammoniacal odor. Its primary application is in gas treatment, where it has been developed to selectively remove hydrogen sulfide from gas streams containing hydrogen sulfide and carbon dioxide mixtures. It can also be effectively used in sweet gas treatment to meet variable carbon dioxide specifications commonly found in the natural gas industry.

    Product Highlights
    • JEFFTREAT MS-100 solvent is a specially formulated, methyldiethanolamine (MDEA)-based gas treating amine.
    • Relative to MEA, DEA and diisopropanolamine (DIPA), JEFFTREAT MS-100 solvent exhibits higher hydrogen sulfide selectivity, higher acid gas loading capability, lower corrosion and degradation tendency, generally lower amine makeup, and lower energy to regenerate.
    • In addition, there is no need for a reclaimer.
    • These characteristics can translate into lower operating costs, increased process capacity of existing equipment, and reduced capital costs for new equipment.
    • Compared to generic MDEA, JEFFTREAT MS-100 solvent will absorb less carbon dioxide, resulting in a higher quality acid gas feed to downstream sulfur plants.

    Product Applications

    JEFFTREAT® MS-100 solvent is specially formulated for selective Hâ‚‚S applications, where appreciable COâ‚‚ slip is needed. These applications include high pressure natural gas, refinery gas or Claus off-gas treating (TGTU).

    Recommended Applications

    JEFFTREAT MS-100 gas treating solvent has been developed to selectively remove hydrogen sulfide from gas streams containing hydrogen sulfide and carbon dioxide mixtures. It can also be effectively used in sweet gas treating to meet variable carbon dioxide specifications found in the natural gas industry. Typical applications for JEFFTREAT MS-100 solvent include:

    • Claus tail gas treating.
    • Natural gas treating.
    • Coal and waste gasification gasses treating.
    • Refinery and petrochemical gas treating.

    Traditionally, primary and secondary alkanolamines having little or no hydrogen sulfide selectivity, such as monoethanolamine (MEA) and diethanolamine (DEA), have been used for the combined removal of hydrogen sulfide and carbon dioxide from gas streams. However, as energy and capital costs increase, and with the increased use of sour crudes and natural gasses, selectively removing hydrogen sulfide from gas streams containing mixtures of hydrogen sulfide and carbon dioxide has become more economically attractive.

    Storage & Handling

    Storage Information
    • 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®, neoprene, and nitrile as these materials tend to swell when exposed to the amine.
    • Kalrez® 1050 LF performs satisfactorily in amine service as well as materials made from polypropylene and Teflon®.
    • 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.
