Separating Chemical Compounds Methods Unit Operations

Example. Separation of NaCl from sea water is an example for separating chemical compounds from a mixture. You know, there are a lot of salts are in the sea water such as NaCl, KCl, MgBr 2 2 and more. But we want to separate NaCl from other chemicals (or decrease amount of other chemicals).

Performance determination of high purity N2 PSA plants

Mar 02, 2020 Pressure swing adsorption (PSA) is a well-established technology applied for the separation of multicomponent gas mixtures. Currently a huge focus is set on CO 2 capture technologies (Salazar Duarte et al. 2017; Schell et al. 2013; Ritter 2015).Nevertheless, PSA is also a well-known and frequently implemented method in traditional industrial processes such as hydrogen purification, …

Industrial Oxygen Its Use and Generation

Cryogenic Separation Cryogenic air separation units (ASU) is an old process used to produce high purity oxygen or nitrogen at high volumes. The process was first developed by Carl Von Linde in 1895 and it remains pretty much the same today. Cryogenics is also the chief method by which liquid oxygen can be produced.

Gas centrifuge for uranium enrichment Energy Education

In World War II, centrifuging was the first process considered for the enrichment of uranium. It was brought to the pilot plant stage before being abandoned for gaseous diffusion . [2] This centrifuge method for the enrichment of uranium is a sophisticated version of the common method used for many years in biology and medicine for ...

Mineral Processing an overview ScienceDirect Topics

Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.
