Course Description
(2) Valve Simulator: Participants will use in the class our state-of-the-art valve simulators to practice some of the skills learnt.
This course is applicable to pressure-relieving and vapor depressuring systems. Although intended for use primarily in oil refineries, it is also applicable to petrochemical facilities, gas plants, liquefied natural gas (LNG) facilities, and oil and gas production facilities. The information provided is designed to aid in the selection of the system that is most appropriate for the risks and circumstances involved in various installations.
This course specifies requirements and gives guidelines for examining the principal causes of overpressure; determining individual relieving rates; selecting and designing disposal systems including such component parts as piping, vessels, flares and vent stacks.
This course is designed to provide participants with a detailed and up-to-date overview of pressure relieving and de-pressuring systems in accordance with API 521. It covers the causes of overpressure and their relieving rates; the overpressure protection philosophy; the determination of individual relieving rates; the individual overpressure causes and their relieving rates; the causes for vacuum and protection against vacuum; the vapor depressuring; and the relief system design and flare header design documentation.
During this interactive course, participants will learn the special considerations for individual PRDs including disposal systems and fluid properties that influence selection and design of disposal systems; the system design load, system arrangement, piping and disposal to a lower-pressure system; and the disposal to flare, disposal to atmosphere and design details for seal and knockout drum.
