General Description
The sulfonation process consists of two continuous falling film ballestra reactors capable of approximately 50/tons per day of active ingredient.
The design of the processing plant encompasses a gas plant, sulfur burning, SO3 conversion, sulfonation reactors, aging, neutralization, hydrolization, pH trim and exhaust gas treatment
The original process was designed for sulfonation of dodecyl benzene and ethoxylated alcohols. It was later converted to sulfonate alpha olefins and lauryl alochols

Plant History
• Chemithon sulfonation plant commissioned in 1977 for liquid detergent business
• Produced Sulfonated Dodecyl benzenes and ethoxylated alcohol surfactants for first 20 years of production
• An additional sidestream Ballestra reactor added in 1982 for sodium lauryl sulfate surfactants
• Refurbished with new reactors and process control system in 1996 to produce Alpha Olefin and Exthoxylated Alcohol surfactants
• Plant scheduled for shutdown in October of 2006

Plant Metrics
• The gas plant of the process is designed to burn 450 lbs/hr of sulfur and is the limiting processing system
• The process has two Ballestra sulfonation reactors, one with seventy two tubes and one with thirteen tubes.
• In 2005, asset utilization was 87% and the plant has produced in excess of 55 million pounds of various surfactants the last two years
