- Abstract
This article introduces the industrial application of domestically independently developed coalescence-adsorption coupling dry deacidification technology in a certain alkylation unit. The results show that after using the coalescence-adsorption coupling dry deacidification technology to replace the alkali washing and water washing systems, all indicators of the alkylated oil meet the requirements, and the sulfur mass fraction of the alkylated oil product is below 8 (µg/g; compared with the alkaline water washing process, using the a coalescence-adsorption coupling dry deacidification process, the reaction by-products are extracted and adsorbed by the acid membrane, and the distillation system operates in a dry manner, avoiding corrosion of downstream equipment and pipelines; acid consumption and energy consumption are reduced by 10% and 8% respectively, achieving water conservation and zero discharge of sewage. At full load, the coalescence-adsorption coupling dry deacidification system can still ensure product qualification after cutting out the adsorption tank. The operation of the device indicates that coalescence in the coupling deacidification technology plays a major role, while adsorption plays a guarantee role. This technology not only improves the intrinsic safety of the unit, but also reduces unit consumption and wastewater discharge.
