Gas Absorption by Alkaline Solutions in a Venturi Scrubber

Abstract

be rectified and the system brought back to steady state within a reasonable period of time.The rare earth chloride (feed) flow rate in the extractor is by far the most important variable to be controlled. The other variables in order of their importance are the HC1 flow rate (scrub solution), the HDEHP flow rate (organic phase),

Tritiated Sulfur Hexafluoride Disposition Strategies

“…The addition of basic compounds to the gas scrubber systems described in Section 3.5 has been widely used for a variety of applications. 6,18,44,45,48,49,50,51 Notably, the addition of sodium hydroxide (NaOH) or potassium hydroxide (KOH) to wet scrubber systems for the removal of H2S and SO2 can greatly increase the efficiency of these systems. 44,50 KOH is particularly suitable for the removal of HF and F2, capturing the fluorine as soluble potassium fluoride (KF) for easier handling.…”

Design of artificial neural networks using a genetic algorithm to predict collection efficiency in venturi scrubbers

“…The main results of this experiment indicate that throat length is not important for increasing the extent of absorption. Uchida and Wen [21] applied a complete mathematical model to gas absorption in a venturi scrubber. They performed mass, heat and momentum balances and obtained a set of differential equations relating the droplet velocity and the gaseous pollutant concentration in both the gas and liquid phase along the axial coordinate of the venturi tube.…”

Predictive Model of Hydrogen Sulfide Absorption by Chelate Solution in a Venturi Scrubber

“…According to other investigators [1,[7][8][9], in order to develop a simple mathematical model for the prediction of the removal efficiency of a venturi scrubber for H 2 S absorption into ferric chelate solution, the following assumptions are introduced:…”
