An annual output of 900ons of sodium dodecyl benzene sulfonate production workshop
Abstract: The design process for production workshop design annual production capacity of 900 tons of sodium dodecyl benzene sulfonate. This product is an anionic surface active agent. Because of low production cost, good performance, and wide application, is a synthetic surfactant detergent dosage is the biggest, is also a part of the production of magnesium, calcium, inorganic salt and organic amine salt, triethanolamine etc.. sodium dodecyl benzene sulfonate has excellent emulsifying properties, is an important part of mixed type emulsifier for the preparation of various pesticides. In this design, with twelve and three alkyl benzene sulfonation prepared twelve benzene sulfonic acid, further reacted with 10% sodium hydroxide, prepared twelve sulfonate. The series products have excellent application performance. Secondly, the following process is materials counting, heat counting, device lectotype,economic indicator, environmental protection technique analysis and safety measure.At last , the flow of production technics is protract including main equipments diagram , materials diagram ,a flat disposal picture of the workshop, the solid disposal picture of the workshop.
Keywords: Twelve benzene; sulfonation; twelve benzene sulfonic acid; technology; workshop layout
