    摘要: Acidic gases containing carbon dioxide are removed from a normally gaseous mixture by absorbing CO.sub.2 from the gaseous mixture with an aqueous solution comprising a basic alkali metal salt or hydroxide and an activator or promoter system for the salt or hydroxide which contains (i) at least one non-sterically hindered diamine defined as having both a primary and a tertiary amino moiety wherein the primary amino moiety is attached to a primary carbon atom, and (ii) an amino acid, and desorbing at least partially the absorbed CO.sub.2 from the aqueous solution.

    摘要: The present invention is an apparatus for simulating corrosion activity in liquid and vapor/condensate corrosion environments. The apparatus includes a container, including a lower region containing the liquid and an upper region, including a condenser, a heater for providing heat to the lower region such that the liquid is maintained at a given temperature, a vacuum pump for providing a partial vacuum at a given pressure in the upper region of the container, one corrosion probe removably positioned in the liquid, and a second corrosion probe removably positioned above the liquid.
