15kt/a废硫酸裂解制酸装置的设计

Design of 15 kt/a spent acid decomposition plant for sulphuric acid production

介绍了山东金诚重油化工有限公司15 kt/a废硫酸裂解制硫酸的再生工艺流程以及设备选型。本装置采用的工艺流程为:废硫酸储罐区、废硫酸高温裂解、余热回收、封闭酸洗净化、"3+2"二转二吸、尾气吸收。该装置解决了烷基化装置废硫酸的处理问题,为高标号汽油的生产奠定了坚实的基础,具有较好的环保效益和社会效益。

The process and optimal selection of equipment of 15 kt / a spent acid decomposition plant for sulphuric acid production in Shandong Jincheng Petrochemical Company are described. The process includes spent acid storage tank,spent acid decomposition at high temperature,waste heat recovery,sealed weak acid scrubbing,＂3 ＋ 1＂double absorption process and tail gas absorption,thus disposing the spent acid from alkylation plant,laying a solid foundation for high grade gasoline production,with good economic and social benefits.
