To systematically investigate the influence of elevated viscosity, polymer-enhanced test mixtures are used. However, conventional test setups are unsuitable for such mixtures, as a bottom product purge is required, leading to partial reflux conditions, which are rarely studied.\n\nTo address this, an alternative setup similar to a stripping column was developed. Using the well-known chlorobenzene\/ethylbenzene test mixture, experiments under both total and partial reflux were conducted and evaluated via McCabe-Thiele analysis and the Delft mass transfer model.\n\nResults show that HETP values (Height Equivalent to a Theoretical Plate) under partial reflux are about 2.7 times higher than under total reflux, indicating a significantly reduced separation performance. The Delft model underestimates HETP values under partial reflux by up to a factor of six. This work thus provides the first systematic quantification of the substantial impact of reflux conditions on distillation performance.\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783689523381\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Buch - 9783689523381","offer_id":57352538980677,"sku":"9783689523381","price":97.2,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/7fc9724f-4dae-4c63-aebf-9738877f2367.jpg?v=1775539491","url":"https:\/\/shop.autorenwelt.de\/products\/separation-performance-measurements-in-distillation-finite-and-infinite-reflux-ratio-operation-von-sven-gutperl","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
