摘要
汽车保有量的迅速增加所来带的大量尾气排放,进而引发对环境污染问题已经越来越引起人们的关注,市场急需高品质的汽车燃料以降低能耗和减少排放。烷基化油由于具有无硫、无芳烃、低烯烃和高辛烷值等优点,作为提高辛烷值的调和组分的比例已经越来越高。HF(氢氟酸)是目前烷基化油生产的主要催化剂,对反应的完成具有重要影响。但是,氢氟酸具有高腐蚀性,少量的泄漏即可对人类健康造成威胁,因此烷基化装置中氢氟酸的安全设计至关重要。本文基于LOPA分析方法详细概述了烷基化装置中控制氢氟酸泄露风险所采取的安全设计措施。
The rapid increase of vehicles and the large number of exhaust emissions brought by it have caused more and more attention to environmental pollution.The market is in urgent need of high quality automotive fuel to reduce energy consumption and reduce emissions.Alkylate have increased as a result of the advantages of no sulfur,no aromatics,low olefins and high octane values,and the proportion of it as the blending components to increase the octane number has becoming more and more higher.HF(hydrofluoric acid) is the main catalyst in the production of alkylate,which has an important influence on the completion of the reaction.However,hydrofluoric acid is highly corrosive,and a small amount of leakage can pose a threat to human health.Therefore,the safety design in alkylation unit is very important.In this paper,the safety design measures adopted in the alkylation unit to control the risk of hydrofluoric acid leakage are described in details based on the LOPA method.
