Hi. I´m the process engineer of an Alkylation HF unit. As many units of this type, we have an acid header, that collects gas streams that may contain HF, and a regular Header. API recommends that a purge gas is provided to minimize stagnant pockets, and corrosive atmosphere in these headers. There is no recommendation for minimum flow/velocity of this purge gas. Does anyone have any criteria regarding minimal flow of this stream??
Thanks,Nagara
