ABSTRACT:
A liquid-liquid contacting apparatus is disclosed. The apparatus is useful in extracting mercaptans from a hydrocarbon stream such as cracked gasoline by nonturbulent countercurrent contacting of the hydrocarbon stream with an aqueous caustic solution. The denser liquid phase flows downward from an upper phase separation zone through a connecting cylindrical contacting zone into a lower phase separation zone. Liquid withdrawal and addition means communicate with each separation zone. A mass of fibrous contacting strands is suspended in the contacting zone. The contacting strands are preferentially wetted by either of the two liquid phases to provide a large surface area which enhances extraction capacity.
