Flare and vent disposal systems - PetroWi

In a shallow seal drum (conventional flashback prevention), the water seals have only a 6- to 10-in. water-column depth. It is important to design the deep seal drum with a proper gas velocity at the staging point to ensure that all the sealing fluid is displaced quickly at the staging pressure (an effect similar to a fast-acting valve actuator).

How do Boilers Work & What is their Use on Ship

The steam produced in the steam drum is known as wet or saturated steam. This steam cannot be used directly as it contains high amounts of moisture. To make this steam usable, it is first dried and heated with the help of a superheater located within the boiler. Once all the moisture content is removed from the steam, the superheated steam can
