JEFFTREAT® M is a clear, water-white to pale amber, hygroscopic liquid with an ammoniacal odor. It is used in tail gas treatment and hydrogen sulfide enrichment units for selectively removing hydrogen sulfide from gas streams containing carbon dioxide. In most cases, these units permit 60 to 80% of the carbon dioxide to remain in the treated gas stream.

    Recommended Applications
    • The alkanolamines and their aqueous solutions will absorb carbon dioxide and hydrogen sulfide at lower temperatures and release the acid gasses at higher temperatures. This forms the basis for pro- cesses which separate carbon dioxide and hydrogen sulfide from gas streams.
    • JEFFTREAT® M solvent is used in tail gas treating and hydrogen sulfide enrichment units for selectively removing hydrogen sulfide from gas streams containing carbon dioxide. These units will, in most cases, permit 60 to 80% of the carbon dioxide to remain in the treated gas stream.
    • JEFFTREAT® M solvent is also used in natural gas plants for the bulk removal of carbon dioxide while producing a gas stream containing 0.25 grains hy- drogen sulfide/100 scf. Bulk carbon dioxide removal can be realized with JEFFTREAT® M sol- vent when the CO2 :H2 S ratio ranges from 100 to 1,000.
    Application

    JEFFTREAT® M should retain its conformance to sales specifications for a period of at least 2 years after date of manufacture if the product is stored at less than 100°F in its undamaged, unopened, factory packaged container.

    Storage & Handling

    Storage and 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.
    • 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.
    Storage Conditions
    • The handling and storage of JEFFTREAT® M solvent presents no unusual problems.
    • The properties and alkaline nature of JEFFTREAT® M solvents should be considered when choosing materials of construction.
    • JEFFTREAT® M 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.
    • 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.
