摘要:
Disclosed are primary sterically hindered aminoacids for use as promoters for alkali metal salts in acid gas scrubbing. The primary sterically hindered aminoacid is selected from 1-amino-cyclopentane carboxylic acid and those represented by the formula: ##STR1## where R.sub.1 and R.sub.2 are independently selected from CH.sub.3, C.sub.2 H.sub.5, and C.sub.3 H.sub.7 ; R.sub.3 and R.sub.4 are independently selected from hydrogen and CH.sub.3 : and n is 0, 2, or 3.

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.
摘要:
The present invention is a process to remove a +2 ionic charged, organically bound metal from a petroleum feed. The process includes contacting feed with aqueous carbon dioxide in the essential absence for emulsion formation.
摘要:
The invention relates to processes for treating acidic crudes or fractions thereof to reduce or eliminate their acidity by addition of effective amounts of crosslinked polymeric amines. The process has utility for crude processing.
摘要:
The invention relates to a process for treating naphthenic acid containing whole crudes or fraction thereof to reduce or eliminate their acidity by contacting the acidic whole crude or fractions thereof at a suitable temperature typically of less than 200.degree. C. with a neutralizing amount typically from 0.25:1 up to 10:1 of overbased detergent. The process has the additional benefits of reducing materials handling problems associated with emulsion formation in treated crudes.
