The use of fuel ethanol will not only save energy, rece pollution, but also for the development of agriculture, driven many other related instries is also significant. Currently, the world proction of fuel ethanol is most sugar cane, corn, Potato plants and straw as raw materials to create the saccharification and fermentation. In the instrial ethanol proction process, As the fermentation process raw materials of carbon dioxide and water vapor can not be directly discharged into the air, carbon dioxide as a subsidiary proct recovery needs, and needs condensing steam after recycling and reuse, fermentation process of ethanol concentration of less need to enter stripper tower to isolate high concentration of ethanol. Distillation then separated into higher concentration of instrial ethanol, ethanol concentrations of up to 99%. The combination of domestic and foreign design heat exchanger and the stripper tower's advanced technology and improved methods of instrial ethanol proction process and provide condenser Distillation tower design, the condenser design includes technology, the strength and structure of the type. Stripper tower design will include structural design, fluid mechanics checked the tray, tray-load performance plans, equipment load calculation. Keywords : instrial ethanol; Condenser; Stripper tower
❷ 乙醇（A.R.）是什麼意思
無水乙醇的意思ar代表的是級別
二級品（AR，重要分析和一般研究工作）
有四種常用規格：優級純或一級品（GR，精密分析和科學研究 alfa工作）；分析純或二級品（AR，重要分析和一般研究工作）；化學純或三級品（CP，工礦及學校一般化學實驗）；實驗試劑(L.P.)。
分析純（AR，紅標簽）： 主成分含量很高、純度較高，干擾雜質很低，適用於工業分析及化學實驗。
❸ 什麼是工業級乙醇
工業級乙醇使用原煤或石油裂解製得，含有大量的甲醇、甲醛等雜質，且不易分離出，因含有甲醇、甲醛等對人體有害物質，絕對不能服用，只能用於非食用化工業的原料或作為燃料。
乙醇是一種有機物，俗稱酒精，化學式為CH3CH2OH（C2H6O或C2H5OH）或EtOH，是帶有一個羥基的飽和一元醇，在常溫、常壓下是一種易燃、易揮發的無色透明液體，它的水溶液具有酒香的氣味，並略帶刺激。有酒的氣味和刺激的辛辣滋味，微甘。
乙醇液體密度是0.789g/cm3(20C°) ，乙醇氣體密度為1.59kg/m^3，沸點是78.3℃，熔點是-114.1℃，易燃，其蒸氣能與空氣形成爆炸性混合物，能與水以任意比互溶。能與氯仿、乙醚、甲醇、丙酮和其他多數有機溶劑混溶，相對密度(d15.56)0.816。
❹ 工業用酒精英文怎麼寫
工業用酒精
英文翻譯如下：
