So I guess if using these for a continuous column using perf plates on stripping side to be able to clear more easily and bubble plates on the rectifier side to be able to balance the flow from stripping side. As stripping side will see a lot more volume compared to rectifying side. If only perf plates you'd be running a 6in rectifier side with a 8in stripping side to keep the rectification side trays loaded.
Hi Michael, The best way to think about turndown ratio is think about the operating range of the system. Or the ability to run the system further away from "spec". A wider operating range allows the operator more latitude to use less or more heat input to influence the finished product while allowing for classic, good plate behavior. I hope that helps?
If you were to install a selection of both types, am I correct in suggesting the perf should sit down in the column under the bubble caps, ie, ex boiler for larger faster volume before fine tuning higher up? Would a perf plate also be of any use just under the dephlem for that higher condensed volume dropping out. Reasons: Just looking at a cheaper, easy maintenance addition plate. Thank you 👍🏼
Hi Matt, As a general rule I would say that mixing plate systems can complicate things more than is needed. Perf plates can and do make a fine finished product. They are cheaper, less prone to fouling, and easier to clean. I personally do not know anyone mixing (actual) plate systems beyond running plates above the kettle and a measure a random packing above a short plate section. It seems their has been good anecdotal outcomes doing so.
