How is the liquid filling level in a container determined?
Thread Content
When submitting the equipment data sheet, what factors are used to determine the liquid fill level of that container?
The liquid filling level in a container is determined by the following factors: the design pressure and temperature of the container, the properties of the liquid (such as density and coefficient of expansion), safety and environmental regulatory requirements, operating conditions (including maximum and minimum liquid levels), as well as considerations related to the expansion or contraction of the liquid. In addition, it is also necessary to refer to relevant process design standards and safety specifications. .
This depends on the functions of your storage tank and the process requirements. If it is equipment used for storage such as tanks in a tank farm, it depends on whether it is liquefied hydrocarbons or liquids ； For buffer tanks used in manufacturing processes, some have a relatively low filling factor
The filling rate of hazardous chemical storage tanks is generally between 80% and 85%
Is this based on experience or are there any regulatory requirements?
For reference: SHT 3007-2014 \"Code for Design of Tank Areas in Petrochemical Storage and Transportation Systems\", 4.1.8 – The design storage high liquid level of storage tanks shall comply with the following provisions:
Petroleum and Chemical Fire Protection Code, 2018 edition: 6.3.9 The storage coefficient for tanks storing liquefied hydrocarbons, liquid ammonia, etc., should not be greater than 0.9; during safety inspections, it is required that this value lie between 0.8 and 0.85
