please i need some help here
i want to ask a few questions about pressure purge method used for inert a vessel:
1-Does The Material/ Gas inside the vessel affect the purge technique ?
2-What about an inlet natural gas filter ( with elements ), does the element affects the purge ?
3- why in some books when implement the equation to calculate number of purge cycle- required for the vessel to be complelty purged- they starts with initial concentration of oxygen after first pressureization not 0.21?
thanks in advance :)
