Pilot plant equilibrium experiments

In applying the model, some mineral parameters, such as numbers, n, and mean radii, Rq of various mineral particles may be estimated by mineralogical techniques. For physical properties such as phase equilibrium constants, K, published ternary and binary data may be used on an approximate basis. Kinetic parameters such as reaction rate constants, k, or mass transfer coefficients can be very roughly estimated based on laboratory experiments. Their values may then be varied in a series of computer runs until the results match pilot plant data. A reasonably good match will, at the same time, confirm the remaining variables, rate equations and other assumptions. 

You have been running experiments in the pilot plant to remove a mercaptan from a gas stream. (Mercaptans are, among other things, responsible for the smells of garlic and skunks.) You find that with a gas feed containing 100 ppm, you can remove 90% of the mercaptan in a tower 18 m tall if you run countercurrently with a pure liquid water feed, using a flow which makes the operating line parallel to the equilibrium line, which is... 

Experiments in a pilot-scale plant demonstrated the feasibility of applying coated monoliths and DX packings or katapak-S successfully as catalyst carriers in reactive stripping. It was proven that the water removal increases the catalyst activity and permits a shift" in the equilibrium. In accordance with the kinetics of this...
