ABSTRACT:
Apparatus is provided for overbasing a petroleum sulfonate in a multi-vessel reaction system in which a first reactor is a plug flow reactor in which a feedstock is fed in the top of the first reactor with carbon dioxide fed near the bottom of the first reactor and with the product of the first reactor passed to a second reactor that is a continuous stirred tank reactor for additional reaction with carbon dioxide. Optionally, the continuous stirred tank reactor is the first in a series of continuous stirred tank reactors with passing a product effluent seriatim through the series of reactors and recovery of product from the last reactor in the series.
