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

Gravity Separation- Principle, Uses and Applications

The earth’s attraction is the principal force in gravity separation, thus the name of the process. The separation is achieved through the relative motion of minerals in response to the force of gravity and one or more other forces in the fluid.
