  • Alkanolamine gas treating composition and process
    Patent number: 4971718
    Abstract: A novel alkanolamine gas treating composition and method for purifying a gas stream containing acid gas impurities. The composition consists essentially of an alkanolamine solvent in an aqueous solution with antimony wherein said alkanolamine solvent includes at least about 1% by weight of methydiethanolamine (MDEA) and at least about 5% monoethanolamine (MEA) by weight of the total solution, and with said antimony present in a concentration of at least about 100 ppm. The combination of antimony and MDEA inhibits corrosion and retards solvent degradation.

  • Process for inhibiting mono and diethanolamine degradation
    Patent number: 4840777
    Abstract: A process for the purification of a gas stream containing impurities comprising (i) passing the gas stream through an aqueous solution of stabilized monoethanolamine or diethanolamine in such a manner that the impurities are absorbed into the monoethanolamine solution or diethanolamine solution to form a rich solution and (ii) regenerating the monoethanolamine or diethanolamine solvent from the rich solution so as to remove the impurities, (iii) recycling the solvent into the aqueous solution in a closed loop and introducing a stabilizer into the recirculating solvent solution in an amount of about 4 to about 25 percent by weight based on the total weight of solution, the stabilizer being methyldiethanolamine.

  • Shaped article for conditioning hair a blend of water-soluble and water-insoluble polymers with interpenetrating networks
    Patent number: 4018729
    Abstract: Articles for conditioning hair have been fabricated by blending water soluble polymers with water insoluble polymers to form interpenetrating networks so that the water soluble polymer can be extracted from the article when wet or when brought in contact with wet hair.
