Minimum Design Metal Temperature determination using Dynamic Simulation

Country:  Everywhere

A considerable amount of equipment and piping in Oil & Gas processing plants is exposed to very low or even cryogenic temperatures during some transient events such as emergency blowdowns, depressurization after prolonged shutdowns or start-ups. Material must be selected within proper temperature ranges according to the Minimum Design Metal Temperature (MDMT).

MDMT calculation is a critical design input, which often leads to material selection constraints. The use of dynamic simulation for such calculations, rigorously replicating the transient conditions of the event, generally finds less restrictive temperatures, ensuring that only the right quantity of every material will be selected and thus potentially leading to important savings in the project’s capital investment.
