Within the activities of the scientific and cultural activity of the Department of Chemical Engineering at the University of Technology for the academic year 2017-2018 Lena Wahib Mahmoud a lecture entitled:
Study the thermodynamic conditions of clathrate hydrates dissociation for ternary systems comprising (refrigerant, salt, water)
Study of the thermodynamic conditions of hydrodite disintegration of the three-component system (cooling gas, water, salt)
Al Khwarizmi Hall in the presence of the Head of Chemical Engineering Department. Assist.Prof.Dr.Jamal Mouna Ali Al-Rubaie, assistants, branch heads, and a number of lecture , students. The dissociation temperature of three types of saline solutions, sodium chloride, potassium bromide and sodium fluoride, was calculated at three concentrations (R134a + water + salt) 0,09, 0.17, 0,26) mol / kg. The Clavirone equation was used to calculate the dissociation temperature of the binary and trigonometric system depending on the practical data of disintegration. The result of the study was done using the case equation of Peng and Robinson, to find the effect of the compressive factor (z) on the dissociation temperature. The output of the binary system (143,8) kjol / m without z and with z (136.08) kjol / mol. The ratio of the calculated values of the tripartite system with the presence of sodium chloride at the three concentrations of non-z (146.7-154.1) kg / m and z (138,02-145,14) kg / mall. The rate of deviation between the two values (5, 8-5.7)%. The other two types of salts have the same results at a deviation of (0.88-0,129)% for the results of sodium chloride salt without z and deviation rate (0,818-0,129)% for the results of sodium chloride with z.
