JEFFTREAT® MS-300

• JEFFTREAT® MS-300 solvent offers the advantage of extremely high H_₂S selectivity over carbon dioxide(CO_₂), which results in lower operating costs, increased equipment capacity, and reduced capital costs for new equipment.
• Proper application of JEFFTREAT® MS-300 solvent may allow shutdown of the incinerator for the off-gas, which could lead to substantial savings for the operator.

JEFFTREAT® MS-300 solvent is designed to meet very low (<10 ppmv) hydrogen sulfide (H_₂S) off-gas specifications in low pressure Claus plant tail gas treating units designed for low H_₂S outlet gas concentration.

JEFFTREAT MS-300 solvent is currently available in tank wagons, tank cars, and in 55-gallon drums.

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® 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® 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.
