Why do LNG storage tanks need pressure relief valves?

LNG storage tanks hold large amounts of LNG at cryogenic temperatures. If that temperature control is lost, or if the BOG compressors fail, the LNG will start vaporising and subject the tank to significant over-pressure in a very short time. Therefore, these tanks must be protected by one or more storage tank pressure relief valves (Figure 2).

Does a storage tank need a pressure relief valve?

In many storage tank applications there is a requirement for a pressure relief valve to be provided for what is called emergency overpressure relief. This overpressure capacity contingency is often caused by an external source of heat such as a fire that boils the liquid contents.

How do relief valves work in LNG service?

Relief valves in LNG service must be carefully designed to handle the two-phase flow and cryogenic temperatures common in these applications. The valves must also seal very tightly, even when subjected to pressures near the setpoint, then consistently and reliably open when the relief setpoint is reached.

How do you adjust a pressure relief valve rated capacity?

since the rupture disc is in the flow path of the pressure relief valve, the asMe section Viii Code mandates that the pressure relief valve rated capacity be adjusted with a capacity combination factor (kc). This correction factor is determined by performing actual flow tests with specific rupture disc and pressure relief valve designs.

What is the KC factor of a Crosby pressure relief valve?

if there has been no combination testing performed then the kc factor is equal to 0.90. Table 8-22 lists the combination tests performed with the Crosby J series direct acting spring loaded valves. for any other Crosby brand or anderson greenwood brand pressure relief valve product used in series with a rupture disc, use a kc factor equal to 0.90.
