After clearing lines following the loading of cargoes such as Naphthas, Xylene, Toluene, Benzene, White Spirits and Kerosenes, it is necessary to wait for a specified period before taking manual ullages or samples. Why is this?
These are all "static accumulator" cargoes. As a cargo line is blown, electrostatically charged bubbles enter the tank and rise through the cargo, generating a high voltage at the surface. It is necessary to wait for a specified period of "relaxation time", to allow the charge to disperse, before introducing any potentially conductive object.
These are all cargoes which may form a wax on the surface of the cargo. As a cargo line is blown, bubbles enter the tank and rise through the cargo. If exposed to cold air as they reach the surface, a wax "carpet" may form across the whole tank. It is necessary to wait for a period of "levelling time" before allowing any air to enter the tank and taking any manual ullages or samples.
These are all cargoes with a high vapour pressure. As a cargo line is blown, the pressure in the ullage space above the surface of the cargo increases. It is necessary to wait for a period of "settling time", before opening the tank lids for sampling and gauging.
These are all cargoes considered to have high noxious vapour levels. As a cargo line is blown, the surface inside the tank is severely disturbed, releasing large quantities of these vapours. It is necessary to wait for a period of "adjusting time", before carrying out any open sampling or gauging.
