Study on an energy-saving process for separation ethylene elycol mixture through heat-pump, heat-integration and ORC driven by waste-heat was written by Wang, Lili;Zhao, Jun;Teng, Junfeng;Dong, Shilong;Wang, Yinglong;Xiang, Shuguang;Sun, Xiaoyan. And the article was included in Energy (Oxford, United Kingdom) in 2022.COA of Formula: C4H10O3 This article mentions the following:
Energy-saving separation processes of Ethylene Glycol (EG) driven by waste heat were investigated. These are basic separation process (BSP) and separation process (SEP) with waste heat recovery (WHRSP). Electricity and heat from waste heat recovery (WHR) were generated for supplying separation system. The optimal operating parameters of each process were determined by the min. total annual cost (TAC). The optimal process was studied by through multi-objective anal.-based exergy, environment and economy performance. The result of exergy anal. indicated that exergy loss of SEP was 1811.40 kW, which 26.38% lower than that of BSP. The environment anal. showed that compared with the benchmarked BSP process, the emissions and emission costs of WHRSP are significantly reduced by about 32.69%. The results of economic anal. showed that TAC of BSP and WHRSP are 2.05×106 $/y, 1.41×106 $/y. TAC of the WHRSP process was 31.54% lower than that of the benchmarked BSP. The WHRSP shows the high energy efficiency, low economy cost and low exergy loss with a great industrial application prospect when compared to the benchmarked process. In the experiment, the researchers used many compounds, for example, 2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6COA of Formula: C4H10O3).
2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.COA of Formula: C4H10O3
