JEFFTREAT® MS-100

• 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.

• 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:

1. Claus tail gas treating
2. Natural gas treating
3. Coal and waste gasification gases treating
4. 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 gases, selectively removing hydrogen sulfide from gas streams containing mixtures of hydrogen sulfide and carbon dioxide has become more economically attractive.

JEFFTREAT® MS-100 solvent is currently available in 55-gallon drums, tank wagons, and tank cars.

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.

• The handling and storage of JEFFTREAT® solvent presents 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® elastomer, neoprene, and nitrile as these materials tend to swell when exposed to the amine. KALREZ® 1050 LF 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.
