dc.description.abstract In this research the VLE100D was tested where experiments were carried out to study the relationship between vapour and liquid at equilibrium under atmospheric condition. The binary system of Water and ethanol have been tested using a circulation-type apparatus. The apparatus (VLE100D) was used to investigate the saturation data in which both vapor and liquid phases are recirculated. The results were used to plot the equilibrium curves at atmospheric pressure, and temperature up to 98℃. Samples of liquid were taken to determine its composition after the system reached an equilibrium state. The liquid phase samples composition were analyzed by refractometer (Abbe, Mettler), the results obtained were compared and found that to be similar to the data available in the literature. All data were compared with NIST data. Finally, the graph of mass fraction of vapour against mass fraction of liquid (x,y diagram) and the graph of temperature against mass of liquid and vapour have been plotted. Acording to the measurements , the saturation temperature data reached a maximum deviation of 2.339% from the data of NIST. The measurment of concentration have been realized by a refractometer type apparatus (Abbe, Mettler) with the thermostat set at 20℃. The concentration has reached a deviation of 0.299% at atmospheric condition. The apparatus has demonstrated its capability to investigate such fluids and also delivered accurate saturation data.   en_US

dc.description.arabic-abstract في هذا البحث تم اخثبار صلاحية الجهاز و قمنا بدراسة العلاقه بين طورين(البخار-السائل) عند الاتزان عند ظروف الضغط الجوي. تم التحقق من بيانات الاتزان باستخدام جهاز فصل الطورين ( VLE100D) الذى يعمل بطريقة اعادة الجريان للطورين الماء المقطر و الايثانول. استخدمت نتائج التجارب لرسم منحني الاتزان عند الضغط الجوي و درجة حرارة تصل الي 98 درجه مئويه. عندما وصل النظام للاتزان أخذت عينات من الطور السائل لقياس تركيزها باستخدام جهاز (Refractometer) وقورنت النتائج المتحصله و البيانات الموجوده في NIST ووجدت متوافقة. في الختام رسم مخطط للحراره و التركيز الوزنى لطور السائل. ووفقا للقياسات كان أقصي انحراف في درجات الاتزان 2.339% تبعا للبيانات الموجوده في NIST بينما وصل أقصي انحراف للتركيز في الطور السائل الي 0.299% . الجهاز له القدرة الفائقه لتحقيق بيانات اتزان دقيقه لعدة سوائل. en_US
