我们催化剂是刚换的,只是关注到这个点了

检测合成塔内反应情况;合成塔阻力增大,如催化剂失活;催化剂使用初期

设计的合成塔在装上催化剂之后,在设计工况下的反应体积缩小及通过床层的阻力将总和,这个压差是用在压缩机功率计算的东西吧,在一个就是对实际运行的指导意义在于压差变化体现这床层的变化。组份、负荷没变,压差变了,那就是床层有异常了。变大是催化剂粉化、烧结了,变小是短路了。以前运行过的设计压差0.2MPa,运行就0.1多点点,现在运行的设计0.03,运行就0.05MPa,催化剂没短路也没烧结,那个值就个理论估算值应该。运行后的压差变化才更有意义。

压差高有催化剂的原因,也有装填的原因,还有反应器本身的原因。
