What is Turndown Ratio And It's Significance In Distillation Column

Turndown Ratio:
                              The ratio between minimum vapor load to maximum vapor load, thus it indirectly defines both the operating range (low or high vapor flow rates) and also the minimum capacity before trays start to leak. A low turndown ratio depicts the tray to be less flexible in operation i.e, it cannot handle a range of vapor flow rates.
