Highly motivated Chemical Engineer with experience since 2008 and proven expertise in Conceptual Design. Utilization the knowledge of Modeling, Simulation and Process Control, and the enthusiasm for team-working, triggered patents and creative designs, including Slack Wax De-oiling, Flare Gas Recovery, Flare Gas Measurement Device, Acid-gas Enrichment Design and Data Validation and Reconciliation Software for a boiler system.Now, beside improving my skills, I do lubricant formulation and enjoy teaching my experience that I learned during several years of practical research in lubricant industry. I also manage my skillful team in CONDEP on conceptual design of processes, and would love to realize my dreams. Supervisors: Dr. M. Shahrokhi Phone: +9893-MMKARIMA

Column output composition obtained with experimental binary coefficients is compared with those obtainded by UNIFAC equation. The results indicate that using UNIFAC for all binrary coefficients results in an unacceptable error in concentration of benzene. If the experimental binary coefficents of benzene with NFM are used and the rest are calculated by UNIFAC equation, the simulation results will be very close to those obtained via experimental binary coefficients. Also it is shown that considering a constant efficiency for all trays is not a valid assumption and therfore efficiency and HETP calculations should be carried out using Rate-Based models. In dynamic simulation, the control loops have been considered and tuned by IMC (Internal Model Control) method. Also a feed forward controller has been designed for rejection of feed flow rate variations. The simulation has been carried out by ASPEN PLUS and ASPEN DYNAMICS version 2006.
