    摘要： A new alkaline absorbent solution containing the additive of a severely-hindered amine salt and/or a severely-hindered aminoacid to a non-hindered amine such as N-methyldiethanolamine (MDEA) is provided. A process for the removal of H.sub.2 S from fluid mixtures using this absorbent solution to produce a very low level of H.sub.2 S in the treated fluid is also provided. The process is also suitable for the selective removal of H.sub.2 S from fluid mixtures comprising H.sub.2 S and CO.sub.2. Use of the above absorbent solution leads to higher selectivity for H.sub.2 S than observed when MDEA is used alone without the additives.

    摘要： The invention relates to a process for treating naphthenic acid--containing whole crudes or fractions thereof to reduce or eliminate their acidity by contacting the acidic whole crude or fraction at a temperature of from about 50.degree. C. to 350.degree. C. with a neutralizing amount of tetraalkylammonium hydroxide, preferably tetramethyl-ammonium hydroxide. The process has the additional benefits of reducing materials handling problems associated with treating oils using liquid solvents and in reducing emulsion formation.
