CATALYST SAMPLING METHOD FOR AN OPERATING CATALYTIC REACTOR |
摘要 |
<p>Small representative samples of catalyst are removed from a fixed bed reactor through a withdrawal conduit and transferred into a sample receiver held at a lower pressure by quickly unsealing the withdrawal conduit and causing a small and sudden gas flow which fluidises catalyst and lifts it into the withdrawal conduit, through which it falls by the action of gravity.</p> |
