简介:产生垢是许多行业都会遇到的一个严重问题,如油气生产、水的储运、发电站等。通常,关于垢的形成研究主要集中在使用大口瓶法了解溶液沉淀过程,并确定沉淀趋势速度和抑制剂效果。最近的一些研究集中于垢在金属表面的沉积。本文综合研究了石灰质垢在溶液和金属表面的形成过程。用三种超饱和成垢液代表油气生产中遇到的典型水样。使用旋转圆盘电极的电化学方法确定金属表面垢量。这一技术考虑旋转圆盘电极表面氧化还原。根据旋转圆盘电极表面氧化还原速率,能够确定垢在该表面覆盖的范围。为了弄清堆积在金属表面的垢的形成和生长,还应用了表面分析法。用扫描电镜(SEM)来分析垢的微观结构。同时,通过垢的溶解,运用感应耦合等离子体(ICP)定量分析溶液中的沉淀量和金属表面的沉积量。本文论证了沉淀和表面沉积与过饱和指数有不同的依赖关系。因此,这两个过程都应加以研究。才能全面了解工业成垢体系。
