Applications in 石油化工
乙烯裂解装置
乙烯装置的裂解炉运行温度为750-900℃,原料包括石脑油、乙烷和液化石油气。淬冷油和淬冷水系统需要耐高温碳钢阀门。裂解气压缩机部分需要合金钢阀门来处理含有焦炭颗粒的腐蚀性工艺气体。
芳烃和 PX 装置
对二甲苯(PX)和芳烃处理装置可处理苯、甲苯和二甲苯,催化剂包括氢氟酸或固态催化剂。耐腐蚀合金,例如哈氏合金C-276和蒙乃尔合金400,适用于酸性环境。波纹管密封阀可防止有毒芳烃的排放。
聚合物生产(PE/PP/PVC)
聚乙烯和聚丙烯装置处理的是高粘度聚合物熔体,这些熔体可能在阀腔内凝固。带蒸汽伴热的夹套阀可防止聚合物冻结。采用最大限度减少死角的原位清洗 (CIP) 设计可防止等级转换期间的产品污染。
硫磺回收和尾气
克劳斯硫磺回收装置处理富含硫化氢的酸性气流。硫磺冷凝器和尾气处理装置需要耐高温硫腐蚀的阀门。采用特殊涂层的316L不锈钢可防止尾气焚烧段受到亚硫酸的侵蚀。
