Sizing Pressure-Relief Devices - AIChE

the sizing of relief devices for single-phase flow — either all gas or all liquid entering the relief device. Although relief devices may never be activated, they must be designed and sized to function correctly every time they are necessary. This article provides an introduction to sizing pressure-relief devices for liquid and vapor service.

Critical Operations & Maintenance Tips Of COPT

Generally, oil tankers have two auxiliary Boilers of nearly 16kg/cm 2 working pressure capacity. This steam gives a tremendous force to the impeller and impeller shaft which produces a high suction force. In result of this good discharging rate can be achieved, which will ultimately save money for the Ship's Owner by reducing port charges
