Research on Domestic and Foreign Standards for Venting Design of Atmospheric and Low-pressure Storage Tanks
Venting device is an important facility of atmospheric and low-pressure storage tanks,and its design requirements are different in domestic and foreign codes.This article compares the foreign standard API 2000-2014 with domestic standards SH/T 3007-2014,HG/T 20570.16-1995,SY/T 0511.1-2010 and GB 50160-2008(2018),and discusses the reasons for overpressure and vacuum in atmospheyic and low-pressure storage tanks,the principles for breathing volume selection,the design and selection of venting devices,and the setup and calculation of inert gas seals.Differences and reasons between domestic and foreign regulatory requirementsare,as well as the rationality and applicability of each requirement are analyzed,in order to provide design and calculation guide for engineering.
