Gravity Separation

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
