Download or read book Mass Transfer and Process Control in Randomly Packed Column a Case Study on CO2 Absorption Wth NaOH written by Srinivas Gavini and published by . This book was released on 2017 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: This thesis studies the mass transfer performance and presents a unified approach in process modeling of a randomly packed column useful for controlling industrial scale CO2 emissions. A case study was conducted on the carbon dioxide absorption with aqueous sodium hydroxide in the packed column. The case study conducted helped in evaluating the mass transfer by using the method of transfer units, which involves the estimation of the height of transfer unit, number of transfer units, and overall gas-phase mass transfer coefficients. The process model developed was an automatic online control and uses a feedback Proportional-Integral-Derivative (PID) Controller. Internal Model Control (IMC) and Ziegler-Nichols (Z-N) tuning methods were used to tune the PID controller based on the process dynamic model and model parameters obtained from the step tests. The overall gas-phase mass transfer coefficient (K Ga) values obtained from the experimental data are comparable to the published data in the literature.

Book excerpt: Packed bed columns are largely employed for absorption, desorption, rectification and direct heat transfer processes in chemical and food industry, environmental protection and also processes in thermal power stations like water purification, flue gas heat utilization and SO2 removal. These Separation processes, are estimated to account for 40%-70% of capital and operating costs in process industry. Packed bed columns are widely employed in this area. Their usage also for direct heat transfer between gas and liquid, enlarge their importance. They are the best apparatuses, from thermodynamical point of view, for mass and heat transfer processes between gas and liquid phase.

Download or read book Mass Transfer with Chemical Reaction in Multiphase Systems written by E. Alper and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 1079 pages. Available in PDF, EPUB and Kindle. Book excerpt: The phenomenon of "mass transfer with chemical reaction" takes place whenever one phase is brought into contact with one or more other phases not in chemical equilibrium with it. This phenomenon has industrial, biological and physiological importance. In chemical process engineering, it is encountered in both separ ation processes and reaction engineering. In some cases, a chemical reaction may deliberately be employed for speeding up the rate of mass transfer and/or for increasing the capacity of the solvent; in other cases the multiphase reaction system is a part of the process with the specific aim of product formation. Finally, in some cases, for instance "distillation with chemical reaction", both objectives are involved. Although the subject is clearly a chemical engineering undertakin~, it requires often a good understanding of other subjects, such as chemistry and fluid mechanics etc., leading to publications in diversified areas. On the other har.d, the subject has always been a major field and one of the most fruitful for chemical engineers.
Download or read book Mass Transfer Area of Structured Packing written by Robert Edison Tsai and published by . This book was released on 2010 with total page 736 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mass transfer area of nine structured packings was measured as a function of liquid load, surface tension, liquid viscosity, and gas rate in a 0.427 m (16.8 in) ID column via absorption of CO2 from air into 0.1 mol/L NaOH. Surface tension was decreased from 72 to 30 mN/m via the addition of a surfactant (TERGITOL[trademark] NP-7). Viscosity was varied from 1 to 15 mPa·s using poly(ethylene oxide) (POLYOX[trademark] WSR N750). A wetted-wall column was used to verify the kinetics of these systems. Literature model predictions matched the wetted-wall column data within 10%. These models were applied in the interpretation of the packing results. The packing mass transfer area was most strongly dictated by geometric area (125 to 500 m2/m3) and liquid load (2.5 to 75 m3/m2·h or 1 to 30 gpm/ft2). A reduction in surface tension enhanced the effective area. The difference was more pronounced for the finer (higher surface area) packings (15 to 20%) than for the coarser ones (10%). Gas velocity (0.6 to 2.3 m/s), liquid viscosity, and channel configuration (45° vs. 60° or smoothed element interfaces) had no appreciable impact on the area. Surface texture (embossing) increased the area by 10% at most. The ratio of effective area to specific area (a[subscript e]/a[subscript p]) was correlated within limits of "13% for the experimental database: [mathematical formula]. This area model is believed to offer better predictive accuracy than the alternatives in the literature, particularly under aqueous conditions. Supplementary hydraulic measurements were obtained. The channel configuration significantly impacted the pressure drop. For a 45°-to-60° inclination change, pressure drop decreased by more than a factor of two and capacity expanded by 20%. Upwards of a two-fold increase in hold-up was observed from 1 to 15 mPa·s. Liquid load strongly affected both pressure drop and hold-up, increasing them by several-fold over the operational range. An economic analysis of an absorber in a CO2 capture process was performed. Mellapak[trademark] 250X yielded the most favorable economics of the investigated packings. The minimum cost for a 7 m MEA system was around $5-7/tonne CO2 removed for capacities in the 100 to 800 MW range.
