| titleOfInvention | Heavy alkylbenzene sulfonic acid sulfonation process production system |
| abstract | The utility model discloses a production system of a sulfonation process of heavy alkyl benzene sulfonic acid, which comprises a sulfonic acid production system and a tail gas treatment system, wherein the sulfonic acid production system comprises a membrane sulfonator group, a gas-liquid separator, an aging tank, a sulfur trioxide removal tower, a hydrolysis pump and a sulfonic acid storage tank which are sequentially connected through a sulfonic acid conveying pipeline; the sulfur trioxide removal tower comprises an upper removal unit and a lower removal unit, the upper removal unit and the lower removal unit are identical in structure, and the sulfur trioxide removal tower comprises a feed liquid distribution pipe and a packing layer which are arranged inside the removal unit, a tail gas discharge pipeline at the top, a waste heat air distribution pipe at the bottom and a feed liquid outlet at the lower side. The method has the advantages that the content of free sulfuric acid in the product is low when the heavy alkylbenzene sulfonic acid is produced by the sulfonation process, the influence of coking and stopping of a sulfonator on normal production operation is avoided, the tail gas absorption liquid can be comprehensively utilized, the waste water discharge is low, the process equipment only needs to be modified on the traditional sulfonation process equipment, the investment cost is low, and the method has very good practical production application value. |
