On the "Zeotropic Mixture" Wikipedia article, I want to add a proper and concise definition of zeotropic mixture[1]. In addition, I want to add applications of zeotropic mixtures in industry, namely, applications in power generation[2][3], distillation[4], and refrigeration[1]. From multiple database searches, these three applications are major applications and much research has been done on them, so I wish to reflect this in the wikipedia article. In addition, I want to dig deeper into the terms already mentioned on the wikipedia article, including "azeotropic" and "temperature glide" and how these terms relate to the definition of zeotropic because these two terms have appeared in several keyword searches on zeotropic and seem to be important to gaining a better understanding of zeotropic mixture.

Pre-Writing for my Drafting on "Zeotropic Mixtures"

Application in Distillation

Zeotropic fluid and gaseous mixtures can be separated by distillation. This process involves the use of distillation columns. When designing distillation processes for separating zeotropic mixtures, the sequencing of distillation columns is vital to saving energy and costs. In addition, other methods can be used to lower the energy or equipment costs required to distill zeotropic mixtures, including combining distillation columns (which uses as much energy as the most energy-consuming separated column), using side columns (saves energy by preventing different columns from carrying out the same separation of mixtures), combining main columns with side columns (saves equipment costs by reducing the number of heat exchangers needed), and re-using waste heat for the system. Re-using waste heat requires the amount of heat and temperature levels of the waste to match that of the heat needed. Thus, using waste heat requires changing the pressure inside evaporators and condensors of the distillation system in order to control the temperatures needed[5]. Controlling the temperature levels in a part of a system is possible with Pinch Technology[6]. These energy-saving techniques have a wide application in industrial distillation of zeotropic mixtures: side columns have been used to refine crude oil, and combining main and side columns is increasingly used[5].
