Design and use of an aqueous solvent solution adapted for use in the removal of contaminate such as, acid gases and sulfur, from a feed stream, the design using computer modeling of a mass transfer unit based on mass transfer rate calculations, including a product preferably formed by adding sodium silicate, water, and at least one alkanolamine selected from the group consisting of monodiethanolamine (MDEA), diethanolamine (DEA), monoethanolamine (MEA), diisopropanolamine (DIPA), triethanolamine (TEA) and similar compounds. The solution can be formed by combining from 1 to about 99% by weight, and more preferably from 5 to 50%, sodium silicate with water, and combining the resulting sodium silicate solution with the desired alkanlolamine(s) at a ratio of from about 1:20 to about 1:1. A novel improved mass transfer unit is disclosed. |
