Gravity Separation - an overview | ScienceDirect Topics

Gravity separation is sufficient for production of good-quality steam at lower boiler operating pressures (e.g., 150 lb/in. 2), where the steam and water density differential is great and the steam drum is adequate for the steam load.. Antifoam agents can significantly reduce carryover caused by chemical factors. Compounds classified as polyalcohols and polyamides are particularly effective in ...

How to Separate Heavy Rare Earth Elements

Mar 07, 2018 · A separation mechanism referred to as displacement chromatography is initiated by a retaining ion loaded onto a strong cation exchange resin (i.e., sulfonic resin) in a separation column. A solution of mixed REE (i.e., mixed-rare-earth band) is saturated on the sulfonic resin in another column called the loading column.
