Slop tank arrangement
Thread Content
There is currently a 15-cubic-meter oil waste tank, connected directly to an oil removal tank (a larger tank) via a pipeline without any valves in between; the larger tank is equipped with a nitrogen seal. If the design pressure of the oil tank is at atmospheric pressure, is it not necessary to install emergency venting ports when considering fire scenarios? Are there any safety hazards?/ Or should the design pressure of the oil tank be increased?
Firstly, it’s not very reasonable that the small and large containers didn’t have valves before； The nitrogen seal pressure generally does not exceed 2 kPa; a design pressure at atmospheric level is usually fine ； The emergency relief valve is primarily designed to prevent overpressure in the nitrogen seal; it has little to do with fires
