Dear All,
We have blanketing tank with PVSV venting to safe location in atm.
We have provided bird screen at outlet of vent pipe.
We need to provide back pressure at outlet of PVSV so that vendor could select right size.
We are proposing 10% of PVSV set pressure for back pressure data due to not having bird screen size info and pressure loss across this.
Typically PVSV set pressure is 0.1 barg. So, total back pressure would be 0.01 barg.
Please let me know
(1)if the present approach is okay in absence of firm data.
(2)How to set bird screen size and determine pressure loss. Are there references available ?
Thanks.
Regards,
