聚胺技术使发电厂能够优化性能

目标：减少流速加速腐蚀，提高 Asset 保护。

<h6>客户挑战</h6> <p>美国西海岸一家800兆瓦的大型联合循环发电厂在其热回收蒸汽发生器（HRSG）的低压蒸发器部分经历了10年的流速加速腐蚀（FAC）。该公司的管理层最近开始寻求一种新的腐蚀控制方法，并与索理思公司取得了联系。</p> <h6>建议的解决方案</h6> <p>索理思推荐工厂试用 Amercor CF6725 缓蚀剂，这是一款在不影响热传导的情况下为锅炉提供高水平腐蚀保护的聚胺产品。为了收集锅炉水中铁的基线数据，使用了 Sentry Corrosion 产品复合取样器，因为正常取样无法提供代表性数据。集成式取样器使用过滤器在一段时间内收集连续样本，过滤器捕获的腐蚀产物的量可以以非常低的 ppb 单位进行准确测量。</p> <h6>实现的结果</h6> <p style="text-align: left;">下表中显示的数据非常值得注意，因为典型的随机取样值在低 ppb 范围内，而铁值实际上在 ppt 范围内。数据显示 Amercor 计划显著降低了 FAC，为 HRSG 提供了有效的腐蚀控制。</p> <table style="width: 451px;
