System and method for treatment of flash vapours sent to a crude distillation column

Abstract: A system and method for treatment of crude hydrocarbon vapours generated from a pre-flash drum, prior to sending these vapours to a distillation column, is disclosed. The crude hydrocarbon vapours are cooled and condensed in a condenser unit, and the immiscible phases are separated in a separator unit into an aqueous phase, a liquid hydrocarbon phase, and a light hydrocarbon containing vapour phase. The light hydrocarbon containing vapour phase and the immiscible liquid hydrocarbon phase are conveyed to the distillation column, whereas the immiscible phase may be further treated to remove dispersed water droplets. Water and salts are removed from the vapours which reduces the water dew point as well as NH 4 C1 de-sublimation temperature at the column overheads. The system and method thereof reduce corrosion problem in the distillation column and simultaneously provide favorable product slate from the given crude blend.

Influence of Mercury Vapour on Chemi-sorption of Oxygen by Nickel Oxide

Abstract: THE vapour pressure of mercury at room temperature (∼10−3 mm) is high enough to necessitate the use of a protective cold trap in vacuum systems where the surface properties of solids are under investigation. Most students of gas adsorption and catalytic processes adopt this precaution, although the practice is by no means universal. Indeed, where the study of condensable vapours is involved it may be necessary to utilize alternative protective devices (for example, gold foil) or to eliminate mercury from the system entirely.
