Cryogenic cooling, or cryo-condensation, could be the most cost-effective method for minimising volatile organic chemical (VOC) emissions from certain processes and conditions, says a new white paper from Linde LLC.
More specifically, VOC emissions in solvent and hydrocarbon storage tanks and manufacturing processes, when certain conditions exist, could be most cost-effectively minimised by cryo-condensation.
Cryo-condensation is a relatively simple process of using the cold from vaporizing nitrogen to condense organic compounds exiting through a vent or in a process gas stream.
The white paper was authored by Robert D’Orazio, Senior Engineer for Linde LLC, who points out that many chemical plants, oilseed processing plants, tank farms and terminals already have liquid nitrogen on-site which is vaporized to gaseous nitrogen for blanketing, purging, pressure transfer and other uses.
