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.. Anti agents can significantly reduce carryover caused by chemical factors. Compounds classified as polyalcohols and polyamides are …

Investigation of residence time and fluid volume in spiral
A review of the above references shows that a clear and quantified effect of the feed rate on the spiral performance still needs to be added. It is hypothesized here that this rather difficult-to-identify effect of the feed rate could be the result of spiral insensitivity to feed rate variation, as shown in Fig. 1. Fig. 1 reproduces the operating window for a WW6 spiral …
