Comparative Analysis of Gas Supply Design for Nitrogen Sealing System of Atmospheric Methanol Storage Tank
The nitrogen sealing system for methanol storage tanks is a commonly used protective measure for atmospheric pressure storage tanks.This paper systematically introduces the principle and pressure selection basis of the nitrogen sealing system.By calculating the gas supply,main equipment investment cost and annual operating cost of the nitrogen sealing system in HG/T20570.16-1995 and API 2000-2014,and analyzing the results,a more accurate and economical calculation method is selected to provide theoretical calculation basis for the nitrogen sealing gas supply of methanol storage tanks in similar projects.
