WebbSummary. Tray efficiency measures the performance of a distillation tray or trays against the maximum theoretical performance. Similarly, a concept called Height Equivalent to Theoretical Plate (HETP) is used to measure the performance in a packed column. This article describes methods of quantifying tray efficiency in distillation tray analysis. WebbBy Johan Avallin, Staff Research Engineer, Cytiva. Good column packing is essential for any chromatographic process and plays a key role in bioprocessing of biopharmaceuticals. A bed packed too densely might crack, which can lead to channeling and early breakthrough. A bed packed too loosely can further compress causing a liquid gap where ...
WebbA theoretical plate is thus a section of the column in which a single equilibrium separation of the studied component occurs between different phases. The gaseous part of the … WebbThus, the defining equation of the height equivalent to a theoretical plate is as follows: HETP = 2 /L, in which is the standard deviation and L the distance traveled. What is the full form of Hetp? Use of the plate height, which is also known as the height equivalent to a theoretical plate (HETP), is acceptable practice in chromatography design even though it …
