Types of separation processes - KSU

Stage and continuous gas-liquid separation processes Chemical process materials are often mixtures of different components. To remove or separate one or more of the components from the original mixture, it must be contacted with another phase. Solute/s can diffuse/s from one phase to another.The two phases are usually

08 Absorption and Stripping - t U

stripping is a gas treatment plant, shown in Fig-ure 8.1 The mixture of the gases (i.e. the gas to be treated in Figure 8.1), from which one component (e.g., CO2 or H2S) in the gas mixture needs to be removed, is passed through an absorber, in which a liquid-phase solvent (e.g., MEA or amine sol-vent in water) is passed though, to absorb that

Design Principles for Liquid-Liquid Extraction | AIChE

Liquid-liquid extraction is an important separation technology for a wide range of applications in the chemical process industries (CPI). Unlike distillation, which is based on boiling point differences, extraction separates components based on their relative solubilities in two immiscible liquids. Extraction is typically chosen over ...

Separation processes - processdesign

Flash Distillation is one of the simpler separation processes to be employed in a chemical plant. The main premise of flash distillation is that a portion of a liquid feed stream vaporizes in a flash chamber or a vapor feed condenses. Vapor-liquid equilibrium will cause the vapor phase and the liquid phase to have different compositions.

separation and purification - Single-stage versus ...

Single-stage versus multistage processes. As shown earlier, ease of separation in equilibrium methods is based on the value of the separation factor, α.When this value is large, separation is easy, requiring little input of work. Thus, if α lies between 100 and 1,000, a single equilibration in liquid-liquid extraction is sufficient to separate at the level of 90 percent or higher.

Gas Absorption Operations - Separation Processes

The gas is forced under pressure through perforated pipes submerged in the scrubbing liquid. As such the gas phase is dispersed and the liquid phase is continuous. As the bubbles rise through the liquid, absorption of the gas occurs. This type of device suffers from the high pressure drop due to the liquid hydrostatic head.

CHAPTER 1 Introduction to Separation Process Engineering

In mechanical equilibrium, the forces between vapor and liquid balance. In the staged separation processes we will study, this usually implies that the pressures are equal. Thus for the cases in this book, p liquid = p vapor (at equilibrium) (1-2) If the interface between liquid and vapor is curved, equal forces do not imply equal pressures.
