Within the scientific and cultural activities of the second semester of the Chemical Engineering Department at the University of Technology for the academic year 2017-2018, the master student Zainab Abdul Amir present a seminar entitled " Static and Dynamic Study of Nitrate Anion Adsorption from Aqueous Solution using Different Adsorbents" on Al-khawarizmi Hall in the presence of the head of department Asst.Prof.Dr.Jamal Mana, both scientific and administrative deputies Asst.Prof.Dr.Khalid Ajmi and Asst.Prof.Dr.Walaa Abdul Al-Hadi and number of faculty.

The student explained in this study the assimilation process of three phases in this work. The experimental work was carried out in the Perspex column with a diameter of 0.092 m and a height of 2 m using the Teflon plate as a distributor containing 42 circular derricks and a circular hole of liquid that was placed at the bottom of the column to study the effect of gas speed, Solid material on both residual gas, liquid and solids, diameter of bubbles and speed of bubbles.

Kerosene and water were used as continuous phases, and air was used as a dispersion phase. The glass beads were used in the diameter of 0.0038 m, the density of 2247 kg / m3, the helping factor from the kerosene treatment reactor located in the sump filter at 0.0025 m, and the density of 2070 kg / m3 as a solid phase. And pressure readings for different speeds of gas and liquid. Surface velocities of liquid and gas are (0.025 m / s - 0.65 m / s) and 0.005 m / s - 0.04 m / s respectively. Various operating variables include speed of gas and liquid, liquid type and particle dimensions. The CFD results were verified from the dynamic characteristics obtained from the simulation with the experimental results using anisys flonte 16.0. The yulian multi-stage particle flow approach was used to predict the overall performance of gas and liquid gas.
