What is the Kremser equation?

What is the Kremser equation?

The Kremser-Brown-Souders equation (nowadays often loosely called the Kremser equation) is the classical method for determining the number of stages, N, in counter-current mass exchange units, when both the operating line and the equilibrium line are linear.

What is stripping in absorption?

Absorption is used to separate gas mixtures, remove impurities, or recover valuable chemicals. The operation of removing the absorbed solute from the solvent is called stripping. Absorbers are normally used with strippers to permit regeneration (or recovery) and recycling of the absorbent.

What is Q in Mccabe Thiele method?

The parameter q is the mole fraction of liquid in the feed, and the slope of the q-line is q / (q – 1). For example, if the feed is a saturated liquid it has no vapor, thus q = 1 and the slope of the q-line is infinite (a vertical line).

What is stripper unit?

A Stripping Column is a chemical equipment used for physical separation, where one or more components are removed from a liquid stream by a vapor stream. In industrial applications, the liquid and vapor streams can have co-current or countercurrent flows. Stripping works on the basis of mass transfer.

Is desorption the same as stripping?

The aim is to remove gases dissolved in water so that they can be transferred into a gas phase in order to obtain water that contains very little dissolved gas. These gases are removed from the liquid phase and carried off in a major gas backflow designated scavenging gas.

What is stripping in chemical engineering?

Stripping is a physical separation process where one or more components are removed from a liquid stream by a vapor stream. In industrial applications the liquid and vapor streams can have co-current or countercurrent flows. Stripping is usually carried out in either a packed or trayed column.

How do you calculate Q in distillation?

The value of q can be controlled by adjusting the amount of preheat the feed stream is subjected to before entering the column. If the feed is a mixture of liquid and vapour, then q is the fraction of the feed that is liquid. For example, if a feed is 25% liquid and 75% vapour, then q = 0.25.
