Process Design for 1000kg/h Alkylbenzene Sulfonates Main Workshop
-- Process Design for Sulfonation and Neutralization Sections
 
Abstract: Sulfonation of benzene is an important step in the production of alkyl benzene sulfonate. The reaction process and technology occupies an important position in the modern chemical industry. According to investigation, analysis and research about resent technologies at home and abroad, use the method of burning sulfur and sulfur trioxide sulfonation technology to produce alkyl benzene sulfonate. In this paper, by the process design of sulfonation, aging, neutralizing and absorbion of exhaust, demonstrate new technology of the production of alkylbenzene sulfonate at home and abroad. In the article the technology of producing alkylbenzene ulfonate , which used pipes-membrane sulfonation technology of Ballestra Co. ( Italy) , has been introduced. The technology has many advantages: rational process, simple equipments in structre, low enengy expense, good proclucts and green.

Key words: sodium alkylbenzene sulfonate, sulfonation technobg, SO3, multi—tube film sulfonation reacto, workshop design
