摘要
文章通过对30万吨/年丙烷/异丁烷混合脱氢装置的废碱氧化处理单元运行过程中出现的管线腐蚀、换热器E-911X和E-912X器壁磨损、进料管线和出料管线频繁堵塞、反应器R-911里面产生硫酸盐颗粒和硫磺颗粒导致反应器器壁严重结垢等问题进行分析。提出防范措施及部分改造建议。
This paper analyzes the corrosion of pipeline,wear of heat exchanger E-911 X and E-912 X,frequent blockage ofincoming and outgoing pipeline and sulfur particles in the reactor R-911 of waste alkali oxidation treatment unit in 300000 tons/year propane/isobutane mixed dehydrogenation device,therefore put forward preventive measures and some modification suggestions.
