Sulphonation Technologies

The plant designs focus on automation with minimum operator interaction.

The typical gas- liquid phase sulf(on)ation plant has sub-systems which are outlined below.

• Sulfur Supply System
• Air Supply System
• S03 Gas Generator System
• Sulfonation System
• Neutralizer System with Dioxane Control and Reduction
• S03 Absorber System
• Effluent Gas Treatment System
• Control Systems

Technithon pioneered the continuous film sulfonation technologies in India and the SAARC region and expanded reach to Western Europe, SE Asia, Middle East and North and South America.

Technithon offers solutions and expertise to deliver:

• Continuous Air+ SO3 sulfonation plants with falling film reactors for both water and oil soluble surfactants
• Adjunct technologies for Low Dioxane in Ether sulfates
• Drying using steam and convective drying systems
• Expertise in Alpha Olefin Sulfonates (AOS) and Methyl Ester Sulfonates (MES)
• Batch processes with Liquid SO3 and Oleum for sulfonating heavy alkyl aryl compounds and Asphalts.
• Continuous Liquid phase sulfonation processes for aromatics, aliphatic and alkyl aryl compounds for both water and oil soluble surfactants
• Continued R&D and process development for sulfonation processes based on Patents for Annular film and Multitube reactors.
