JEFFTREAT®M is available within the JEFFTREAT® product line. This solvent is for customers who choose to utilize generic methyl diethanolamine (MDEA) rather than a formulated MDEA solvent.
- 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 processes 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 hydrogen sulfide/100 scf.
- Bulk carbon dioxide removal can be realized with JEFFTREAT® M solvent when the CO2:H2S ratio ranges from 100 to 1,000.

Storage & Handling
- Storage and Shelf Life Conditions
- 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.
- The handling and storage of JEFFTREAT M 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.
